Navy Irregular Warfare and Counterterrorism Operations 
 
Summary 
In the years following the terrorist attacks of September 11, 2001, the Navy has carried out a 
variety of irregular warfare (IW) and counterterrorism (CT) activities. Among the most readily 
visible of these were operations carried out by Navy sailors serving ashore in the Middle East and 
Afghanistan, as well as the May 1-2, 2011, U.S. military operation in Abbottabad, Pakistan, that 
killed Osama bin Laden. 
During these years, the Navy took certain actions intended to improve its IW capabilities. For 
example, the Navy established the Navy Expeditionary Combat Command (NECC) informally in 
October 2005 and formally in January 2006. NECC consolidated and facilitated the expansion of 
a number of Navy organizations that have a role in IW operations. The Navy also established the 
Navy Irregular Warfare Office in July 2008, published a vision statement for irregular warfare in 
January 2010, and established “a community of interest” (COI) to develop and advance ideas, 
collaboration, and advocacy related to IW in December 2010. 
The Navy during these years also reestablished its riverine force and initiated The Global 
Maritime Partnership, which was a U.S. Navy initiative to achieve an enhanced degree of 
cooperation between the U.S. Navy and foreign navies, coast guards, and maritime police forces, 
for the purpose of ensuring global maritime security against common threats. In addition, the 
Navy operated the Southern Partnership Station (SPS) and the Africa Partnership Station (APS), 
which were Navy ships, such as amphibious ships or high-speed sealift ships, that deployed to the 
Caribbean and to waters off Africa, respectively, to support U.S. Navy engagement with countries 
in those regions, particularly for purposes of building security partnerships with those countries 
and for increasing the capabilities of those countries for performing maritime-security operations. 
The Navy’s current IW and CT activities pose a number of potential oversight issues for 
Congress, including how much emphasis to place on IW and CT activities in Navy budgets, 
particularly in a context of constraints on Navy budgets and Navy desires to devote resources to 
developing “high end” combat capabilities for countering improved conventional military 
capabilities of countries such as China and Russia.

Navy Irregular Warfare and Counterterrorism Operations 
 
Introduction 
This report provides background information and potential issues for Congress on the Navy’s 
irregular warfare (IW) and counterterrorism (CT) operations. The Navy’s IW and CT activities 
pose a number of potential oversight issues for Congress, including how much emphasis to place 
on IW and CT activities in Navy budgets, particularly in a context of constraints on Navy budgets 
and Navy desires to devote resources to developing “high end” combat capabilities for countering 
improved conventional military capabilities of countries such as China and Russia. Congress’s 
decisions regarding Navy IW and CT operations can affect Navy operations and funding 
requirements, and the implementation of the nation’s overall IW and CT strategies. 
This report focuses on Navy IW and CT operations. Another CRS report discusses U.S. special 
operations forces (SOF) across the military services.1 
For an overview of the strategic and budgetary context in which Navy IW and CT operations may 
be considered, see CRS Report RL32665, Navy Force Structure and Shipbuilding Plans: 
Background and Issues for Congress, by Ronald O'Rourke. 
Background 
Navy Irregular Warfare (IW) Operations 
Note on Terminology 
The Navy has sometimes used the phrase confronting irregular challenges (CIC) instead of the 
term irregular warfare. For purposes of convenience, this report continues to use the term 
irregular warfare and the abbreviation IW. 
Navy IW Operations in Middle East and Afghanistan 
In the years following the terrorist attacks of September 11, 2001, the Navy carried out a variety 
of irregular warfare (IW) and counterterrorism (CT) activities. Among the most readily visible of 
these were operations carried out by Navy sailors serving ashore in the Middle East and 
Afghanistan. Regarding current operations in the Middle East, the Department of the Navy 
(DON) states the following in its FY2020 budget highlights book: 
The Marine Corps has an active duty force of approximately 1,300 Marines ashore in the 
U.S.  CENTCOM  area  of  operations  (AOR)  and  another  roughly  850  Marine  Reserve 
members supporting CENTCOM. Beyond the Marines participating in counterinsurgency, 
security cooperation, and civil-military operations; on any given day there are about 1,000 
Sailors ashore and another roughly 6,500 afloat throughout the CENTCOM AOR. These 
sailors are conducting activities such as air operations, maritime infrastructure protection, 
combat  construction  engineering,  cargo  handling,  combat  logistics,  maritime  security, 
detainee operations, customs inspections, civil affairs, base operations, and other forward 
presence activities.2

Navy IW Operations Elsewhere 
In addition to participating in U.S. military operations in the Middle East and Afghanistan, Navy 
IW operations in the years following the terrorist attacks of September 11, 2011, have also 
included the following: 
  security force assistance operations, in which forward-deployed Navy ships 
have exercised and worked with foreign navies, coast guards, and maritime 
police forces, so as to improve their abilities to conduct maritime security 
operations; 
  civic assistance operations, in which forward-deployed Navy units, including 
Navy hospital ships, expeditionary medical teams, fleet surgical teams, and naval 
construction units have provided medical and construction services in foreign 
countries as a complement to other U.S. diplomatic and development activities in 
those countries; 
  disaster relief operations, of which Navy forces have performed several in 
recent years; and 
  counter-piracy operations, particularly off the Horn of Africa. 
DON states in its FY2020 budget highlights book that 
In the past year, the Marine Corps executed 170 operations, eight amphibious operations, 
115  theater  security  cooperation  events  and  participated  in  51  exercises  and  relief 
operations  for  Hurricanes  Maria,  Florence,  and  Michael.  Within  the  context  of  these 
efforts, Amphibious Ready Groups / Marine Expeditionary Units (ARG/MEU) supported 
Combatant  commands  along-side  regional  partners  providing  a  range  of  deliberate  and 
crisis response options. Major exercises were held in Romania, Israel, Jordan, Malaysia, 
and  off  the  coast  of  Djibouti.  The  Marine  Corps  also  participated  in  theater  security 
cooperation (TSC) exercises held in Brazil, Latvia, Jordan, Mexico, and Philippines that 
enhanced military cooperation, capability, and interoperability with partner nations while 
sustaining  a  ready,  forward  presence  in  support  of  the  Combatant  Commander 
requirements…. 
The  Navy  has  active  and  reserve  forces  continually  deployed  in  support  of  contingency 
operations  overseas  serving  as  members  of  Carrier  Strike  Groups,  Expeditionary  Strike 
Groups, Special Operating Forces, Seabee units, Marine forces, and medical units; some 
also serve as Individual Augmentees (IAs).3 
Navy Individual Augmentees (IAs) 
Some of the Navy’s contributions to IW operations around the world in the years following the 
terrorist attacks of September 11, 2001, were made by Navy individual augmentees (IAs)—
individual Navy sailors assigned to various DOD operations. DON stated in 2014 that 
Navy IAs are providing combat support and combat service support for Army and Marine 
Corps  personnel  in  Afghanistan.  As  IAs  they  are  fulfilling  vital  roles  by  serving  in 
traditional Navy roles such as USMC support, maritime and port security, cargo handling, 
airlift support, Seabee units, and as a member of joint task force/Combatant Commanders 
staffs.  Non-traditional  roles  include  detainee  operations,  custom  inspections  teams,  and 
civil affairs.4

Navy Irregular Warfare and Counterterrorism Operations 
 
Navy Counterterrorism (CT) Operations 
In General 
Navy CT operations (and anti-terrorism/force protection activities) at various points since the late 
1990s, and particularly in the years following the terrorist attacks of September 11, 2001, have 
included the following: 
  Operations by Navy special operations forces, known as SEALs (an acronym 
standing for Sea, Air, and Land), that have been directed against terrorists;5 
  Tomahawk cruise missile attacks on suspected terrorist training camps and 
facilities, such as those reportedly conducted in Somalia on March 3 and May 1, 
2008,6 and those conducted in 1998 in response to the 1998 terrorist bombings of 
U.S. embassies in East Africa;7 
  surveillance by Navy ships and aircraft of suspected terrorists overseas; 
  maritime intercept operations (MIO) that were aimed at identifying and 
intercepting terrorists or weapons of mass destruction at sea, or potentially 
threatening ships or aircraft that are in or approaching U.S. territorial waters—an 
activity that has included Navy participation in the multilateral Proliferation 
Security Initiative (PSI);8 
  protection of forward-deployed Navy ships, an activity that was intensified 
following the terrorist attack on the Navy Aegis destroyer Cole (DDG-67) in 
October 2000 in the port of Aden, Yemen;9 
  protection of domestic and overseas Navy bases and facilities; 
  working with the Coast Guard to build maritime domain awareness (or MDA, 
meaning a real-time understanding of activities on the world’s oceans), and

Issues for Congress, by Raphael F. Perl and Ronald O'Rourke (out of print, but available to congressional clients upon

The first ever attack by the newly-announced Indian Subcontinent branch of Al Qaeda went really, 
really, poorly. The attack launched last Saturday [September 13] in Pakistan seems to have targeted 
the wrong ship. 
Fighters of the Islamic terror group branch that was unveiled two weeks ago had planned to storm 
an American aircraft carrier at a Karachi port, but found a Pakistani Navy ship in its place, The 
Telegraph reports. The attackers suffered heavy casualties as the Pakistani Navy easily 
overpowered their attempt. Three of the al-Qaeda fighters were killed and seven were arrested 
according to Pakistani officials. Two Pakistani Naval guards were wounded.

engaging with the U.S. Coast Guard to use the National Strategy for Maritime 
Security to more rapidly develop capabilities for Homeland Security, particularly 
in the area of MDA; 
  assisting the Coast Guard in port-security operations;10 
  developing Global Maritime Intelligence Integration (GMII) as part of Joint 
Force Maritime Component Command (JFMCC) and Maritime Domain 
Awareness (MDA); and 
  operations by the Naval Criminal Investigative Service (NCIS), for which 
combating terrorism is a core mission area.11 
DON stated in 2014 that 
While  forward,  acting  as  the  lead  element  of  our  defense-in-depth,  naval  forces  will  be 
positioned for increased roles in combating terrorism.... Expanded Maritime Interdiction 
Operations  are  authorized  by  the  President  and  directed  by  the  Secretary  of  Defense  to 
intercept vessels identified to be transporting terrorists and/or terrorist-related materiel that 
poses an imminent threat to the United States and its allies..... 
We  have  done  small,  precise  attacks  against  terrorist  cells  and  missile  attacks  against 
extremist sanctuaries.12 
DON stated in 2013 that 
Our defense efforts are aimed at countering violent extremists and destabilizing threats, as 
well as upholding our commitments to allies and partner states. These armed adversaries 
such  as  terrorists,  insurgents,  and  separatist  militias  are  a  principal  challenge  to  U.S. 
interests in East Africa.13

Daily, September 4, 2008; and Dan Taylor, “New Network Allows Navy To Track Thousands of Ships Worldwide,” 
Inside the Navy, September 8, 2008. For more on the Coast Guard and port security, see CRS Report RL33383, 
Terminal Operators and Their Role in U.S. Port and Maritime Security, by John Frittelli and Jennifer E. Lake, and 
CRS Report RL33787, Maritime Security: Potential Terrorist Attacks and Protection Priorities, by Paul W. Parfomak 
and John Frittelli (out of print, but available to congressional clients upon request). 
11 NCIS states on its website that “the NCIS mission is to investigate and defeat criminal, foreign, and terrorist 
intelligence threats to the United States Navy and Marine Corps, wherever they operate: ashore, afloat, or in 
cyberspace,” and that combating terrorism is a core mission area for NCIS. Regarding this mission, the website states 
that 
Protecting the naval forces from violent extremist organizations and individuals is one of NCIS’ 
highest priorities. As the primary law enforcement and counterintelligence component for the naval 
services, NCIS is focused on countering threats to the physical security of Sailors, Marines, and 
Department of the Navy (DON) civilian personnel and on preventing terrorist attacks against 
installations and ships. 
NCIS is responsible for detecting, deterring, and disrupting terrorism worldwide through a wide 
array of offensive and defensive capabilities. Offensive operations aim at identifying and 
interdicting terrorist activities. In defensive operations, NCIS supports key DON leaders with 
protective services and performs physical security assessments of military installations and related 
facilities—including ports, airfields, and exercise areas to which naval expeditionary forces deploy.

Navy Irregular Warfare and Counterterrorism Operations 
 
An April 8, 2013, press report about U.S. counterterrorism operations stated, regarding one 
particular operation, that 
The uncertainties were evident nine months into Mr. Obama’s first term, when intelligence 
agencies tracked down Saleh Ali Saleh Nabhan, a suspect in the attacks on two American 
embassies in East Africa in 1998. 
The original plan had been to fire long-range missiles to hit Mr. Nabhan and others as they 
drove in a convoy from Mogadishu, Somalia, to the seaside town of Baraawe. But that plan 
was scrubbed at the last minute, and instead a Navy SEALs14 team helicoptered from a ship 
and  strafed  Mr.  Nabhan’s  convoy,  killing  him  and  three  others.  The  SEALs  landed  to 
collect DNA samples to confirm the identities of the dead.15 
May 1-2, 2011, U.S. Military Operation That Killed Osama Bin Laden 
The May 1-2, 2011, U.S. military operation in Abbottabad, Pakistan, that killed Osama bin 
Laden—reportedly called Operation Neptune’s Spear—reportedly was carried out by a team of 
23 Navy special operations forces, known as SEALs (an acronym standing for Sea, Air, and 
Land). The SEALs reportedly belonged to an elite unit known unofficially as Seal Team 6 and 
officially as the Naval Special Warfare Development Group (DEVGRU).16 The SEALs reportedly 
were flown to and from Abbottabad by Army special operations helicopters. Bin Laden’s body 
reportedly was flown by a U.S. military helicopter from Abbottabad to a base in Afghanistan, and 
from there by a Marine Corps V-22 tilt-rotor aircraft to the aircraft carrier Carl Vinson (CVN-70), 
which was operating at the time in the Northern Arabian Sea. A few hours later, bin Laden’s body 
reportedly was buried at sea from the ship. Differing accounts have been published regarding 
certain details of the operation.17 
Press reports in July 2010 stated that U.S. forces in Afghanistan included at that time a special 
unit called Task Force 373, composed of Navy SEALs and Army Delta Force personnel, whose 
mission is “the deactivation of top Taliban and terrorists by either killing or capturing them.”18  
A July 2015 Government Accountability Office (GAO) report19 and a separate CRS report20 
provide additional background information on the SEALs. Another CRS report provides further 
discussion of the operation that killed Osama bin Laden.21

Detention of Terrorist Suspects on U.S. Navy Ships 
An August 16, 2015, press report stated the following: 
After a suspected militant was captured last year to face charges for the deadly 2012 attacks 
on Americans in Benghazi, Libya, he was brought to the U.S. aboard a Navy transport ship 
on a 13-day trip that his lawyers say could have taken 13 hours by plane. 
Ahmed Abu Khattala faced days of questioning aboard the USS New York from separate 
teams  of  American  interrogators,  part  of  a  two-step  process  designed  to  obtain  both 
national security intelligence and evidence usable in a criminal prosecution. 
The case, still in its early stages, is focusing attention on an interrogation strategy that the 
Obama  administration  has  used  in  just  a  few  recent  terrorism  investigations  and 
prosecutions.  Abu  Khattala’s  lawyers  already  have  signaled  a  challenge  to  the  process, 
setting the stage for a rare court clash over a tactic that has riled civil liberties groups but 
is seen by the government as a vital and appropriate tool in prosecuting suspected terrorists 
captured overseas. 
“I think they view it as important to show that terrorists can be prosecuted in U.S. courts, 
and  this  is  an  attempt  to  find  a  compromise  between  using  people  they  capture  as 
intelligence  assets  and  prosecuting  them  in  U.S.  courts,”  said  David  Deitch,  a  former 
Justice Department terrorism prosecutor. “It’s a very hard balance to strike—and may not 
be possible.” 
The  administration  has  turned  to  questioning  in  international  waters  as  an  alternative  to 
past  practices  in  which  suspects  were  sent  to  the  U.S.  detention  facility  at  Guantanamo 
Bay, Cuba, or secret CIA prisons. The process ordinarily begins with questioning from a 
specialized  team  of  interrogators  who  collect  intelligence  that  can  inform  government 
decisions,  such  as  for  drone  strikes,  but  cannot  be  used  in  court.  Then  a  team  of  FBI 
investigators starts from scratch, advising the detainee of his Miranda rights, such as the 
right to remain silent, and gathering statements that prosecutors can present as evidence in 
a trial. 
Some legal experts expect the hybrid interrogation technique to survive legal challenges. 
But defense lawyers are concerned that such prolonged detention can be used to wrangle a 
confession or amounts to an end-run around the government’s obligation to promptly place 
a suspect before a judge. 
“Basically by holding the suspects on a ship and delaying their presentment in federal court, 
they're  able  to  get  a  leg  up  in  interrogations,”  said  Seton  Hall  University  law  professor 
Jonathan Hafetz, who has handled terrorism cases. 
Abu Khattala is facing charges in Washington in the Sept. 11-12, 2012, attack on the U.S. 
diplomatic mission in Benghazi that killed U.S. Ambassador Chris Stevens and three other 
Americans. Following his June 2014 capture in Libya by U.S. special forces, he was placed 
aboard a Navy ship that his lawyers say made its way to the U.S. as slowly as possible to 
allow maximum time for interrogation. They say Abu Khattala was questioned for days by 
representatives from the High Value Detainee Interrogation Group, then for another stretch 
by FBI agents.... 
One early point of contention in the court case is the onboard interrogation. Abu Khattala’s 
lawyers  submitted  court  filings  this  month  contending  that  the  government  held  him 
“captive  on  a  military  ship—without  the  protection  of  and  in  spite  of  constitutional 
guarantees—for the explicit purpose of illegally interrogating him for almost two weeks.” 
Federal prosecutors have yet to respond.

Whatever a judge decides, the case taps into a broader legal debate about the prosecution 
of  terrorist  suspects  and  presents  a  rare  opportunity  for  a  possible  ruling  on  the 
admissibility of statements gathered aboard a military vessel.22

Appendix E. 
Navy Initiatives to Improve Its IW and CT Capabilities 
In the years following the terrorist attacks of September 11, 2001, the Navy took certain actions 
intended to improve its IW and CT capabilities and activities, including those discussed below. 
Some of the actions the Navy took during those years are described briefly below. 
Navy Irregular Warfare Office (NIWO)/Navy Warfare Group (NWG) 
The Navy in July 2008 established the Navy Irregular Warfare Office (NIWO) so as to 
“institutionalize current ad hoc efforts in IW missions of counterterrorism and counterinsurgency 
and the supporting missions of information operations, intelligence operations, foreign internal 
defense and unconventional warfare as they apply to [CT] and [counterinsurgency].”23 
In January 2013, the Navy directed the establishment of a Navy Warfare Group (NWG) “to 
provide a dedicated organization to systematically evaluate, develop, and implement new 
strategic concepts deemed useful to the service....” NIWO was disbanded, and its responsibilities 
were transferred to NWG, which is to “[s]erve as the Navy lead for irregular warfare (IW) to 
incorporate IW into Navy capstone documents and to inform the PPBE [Planning, Programming, 
Budgeting, and Execution] process.”24 
2010 Navy Vision Statement for Countering Irregular Challenges 
The Navy in January 2010 published a vision statement for countering irregular challenges, which 
stated the following in part: 
The U.S. Navy will meet irregular challenges through a flexible, agile, and broad array of 
multi-mission  capabilities.  We  will  emphasize  Cooperative  Security  as  part  of  a 
comprehensive government approach to mitigate the causes of insecurity and  instability. 
We will operate in and from the maritime domain with joint and international partners to 
enhance regional security and stability, and to dissuade, deter, and when necessary, defeat 
irregular forces.25 
The full text of the vision statement is reproduced in Appendix C.

Navy Community of Interest (COI) for Countering Irregular Challenges 
The Navy in December 2010 established “a community of interest [COI] to develop and advance 
ideas, collaboration and advocacy related to confronting irregular challenges (CIC).”26 
Navy Expeditionary Combat Command (NECC) 
The Navy Expeditionary Combat Command (NECC), headquartered at Naval Amphibious Base, 
Little Creek, VA, was established informally in October 2005 and formally on January 13, 2006. 
NECC consolidated and facilitated the expansion of a number of Navy organizations that have a 
role in IW operations. DON stated in 2014 that 
Navy Expeditionary Combat Command (NECC) is a global force provider of expeditionary 
combat service support and force protection capabilities to joint warfighting commanders. 
It  is  responsible  for  centrally  managing  the  current  and  future  readiness,  resources, 
manning,  training  and  equipping  of  a  scalable,  self-sustaining,  integrated  expeditionary 
force  of  active  and  reserve  sailors.  Expeditionary  sailors  are  deployed  from  around  the 
globe, supporting contingency operations and Combatant Commanders’ Theater Security 
Cooperation Plans, providing a forward presence of waterborne and ashore anti-terrorism 
force protection; theater security cooperation and engagement; and humanitarian assistance 
and disaster relief.27 
DON also stated in 2014 that 
The Reserve Component expeditionary forces are integrated with the Active Component 
forces to provide a continuum of capabilities unique to the maritime environment within 
NECC. Blending the AC and RC brings strength to the force and is an important part of 
the Navy’s ability to carry out the Naval Maritime Strategy from blue water into green and 
brown water and in direct support of the Joint Force. The Navy Reserve trains and equips 
over  half  of  the  Sailors  supporting  NECC  missions,  including  naval  construction  and 
explosive ordnance disposal in the CENTCOM region, as well as maritime expeditionary 
security,  expeditionary  logistics  (cargo  handling  battalions),  maritime  civil  affairs, 
expeditionary  intelligence,  and  other  mission  capabilities  seamlessly  integrated  with 
operational forces around the world. In addition, Coastal Riverine Group 2 has taken on a 
new  armed  escort  mission  for  High  Value  Units  (HVU)  which  has  traditionally  been 
provided by the U.S. Coast Guard. The escort enhances force protection for HVUs while 
transiting into and out of CONUS ports during restricted maneuvering.28 
Global Maritime Partnership 
The Global Maritime Partnership was a U.S. Navy initiative to achieve an enhanced degree of 
cooperation between the U.S. Navy and foreign navies, coast guards, and maritime police forces, 
for the purpose of ensuring global maritime security against common threats. DON stated in 2014 
that “through partnerships with a growing number of nations, including those in Africa and Latin 
America, we will strive for a common vision of freedom, stability, and prosperity.”29

Partnership Stations 
The Southern Partnership Station (SPS) and the Africa Partnership Station (APS) were Navy 
ships, such as amphibious ships or high-speed sealift ships, that deployed to the Caribbean and to 
waters off Africa, respectively, to support U.S. Navy engagement with countries in those regions, 
particularly for purposes of building security partnerships with those countries, and for increasing 
the capabilities of those countries for performing maritime-security operations. The SPS and APS 
can be viewed as specific measures for promoting the above-mentioned global maritime 
partnership. A July 2010 Government Accountability Office (GAO) report discussed the APS.30 
Coastal Riverine Force 
The Navy in May 2006 reestablished its riverine force by standing up Riverine Group 1 at Naval 
Amphibious Base, Little Creek, VA (now part of Joint Expeditionary Base Little Creek-Fort 
Story, or JEBLC-FS). Riverine Group 1 included three active-duty riverine squadrons of 12 boats 
each that were established in 2006-2007. Operations of the squadrons from 2006 to 2011 included 
multiple deployments to Iraq for the purpose, among other things, of relieving Marines who until 
2006 had been conducting maritime security operations in Iraqi ports and waterways. 
On June 1, 2012, the Navy merged the riverine force and the Maritime Expeditionary Security 
Force (MESF) to create Coastal Riverine Force (CORIVFOR). The Navy stated that CORIVFOR 
“performs core maritime expeditionary security missions in the green and brown waters, bridging 
the gap between traditional Navy blue water operations and land-based forces, providing port and 
harbor security for vital waterways and protection of high value assets and maritime 
infrastructure.”31 The Navy stated that CORIVFOR was scheduled to reach initial operating 
capability (IOC) in October 2012 and full operational capability (FOC) in October 2014, and that 
“all current and scheduled routine deployments will continue as normal.”32 
A July 14, 2014, news report states the following: 
In 2012, the Navy merged Riverine Forces and Maritime Expeditionary Security Forces to 
form the Coastal Riverine Force. There are currently seven squadrons. Squadrons 1, 3 and 
11 are home ported on the west coast and Squadrons 2, 4, 8 and 10 are home ported on the 
east coast. The force currently consists of both active and reserve service members who 
man and operate more than 100 boats, ranging from rubber combat raiding crafts to 53-
foot command boats that can carry up to 26 personnel.33 
A January 18, 2013, Navy news report stated the following:

Sailors, former Riverines, and family members attended a disestablishment ceremony for 
Naval  Expeditionary  Combat  Command’s  Riverine  Squadron  (RIVRON)  3  at  Naval 
Weapons Station Yorktown, Jan. 17. 
The  disestablishment  marks  the  merger  of  offensive  Riverine  forces  with  defensive 
Maritime Expeditionary Security Forces to form the Coastal Riverine Force (CORIVFOR), 
formally established June 1[, 2012].... 
CORIVFOR’s primary mission is to conduct maritime security operations across all phases 
of military operations by defending high value assets, critical maritime infrastructure, ports 
and  harbors,  both  inland  and  on  coastal  waterways,  and  when  commanded,  conduct 
offensive combat operations. 
The  budget-initiated  merger  moved  portions  of  the  force  to  San  Diego  as  part  of  the 
National Defense Strategy’s rebalance to the Pacific, which will bring Riverine capability 
to the West coast for the first time since 1974, according to Capt. Eric B. Moss, commander 
of Coastal Riverine Group 1, formerly Maritime Expeditionary Security Group 1. 
“The Riverine forces will do what they’ve always done, which is continuing to hone their 
skills and work in brown water and green water areas,” said Moss. “There is no abatement 
of requirements. We continue to get missions and are sourced to meet those requirements. 
We’re doing the same with less.” 
The merge cuts the former seven active Maritime Expeditionary  Security Force (MESF) 
squadrons and three active RIVRONs down to three active Coastal Riverine squadrons and 
four reserve squadrons. 
“This is a reduction in capacity, but not in capability,” said Moss. “I would say this is a 
very  affordable  force.  We  are  light,  expeditionary,  and  bring  a  lot  capability  in  small 
packages.  We  are  familiar  with  disaggregated  operations,  so  immediately  we  give  the 
combatant commander a tailor-able and scalable force.”... 
Commissioned July 6, 2007, RIVRON 3 served two deployments in Iraq, fulfilling a total 
of  502  combat  missions,  268  water  security  operations  and  countless  U.S./Iraq  tactical 
convoy operations.34 
Other Organizational Initiatives 
Other Navy initiatives in recent years for supporting IW and CT operations include establishing a 
reserve civil affairs battalion, a Navy Foreign Area Officer (FAO) community consisting of 
officers with specialized knowledge of foreign countries and regions, a maritime interception 
operation (MIO) intelligence exploitation pilot program, and an intelligence data-mining 
capability at the National Maritime Intelligence Center (NMIC).

FY2020 Funding Request 
Overview 
DON states that the proposed FY2020 budget “continues funding to counter the Islamic State of 
Iraq and the Levant (ISIL) and for operations in Afghanistan, the Horn of Africa, and other 
locations in theater, as well as for the European Deterrence Initiative,” and “supports building a 
more experienced, better trained, and more capable force by increasing the number of Marines 
with special skills, like those required for special operations, intelligence operations, electronic, 
information, and cyber warfare.”36 Special Operations Command’s (SOCOM’s) proposed 
FY2020 budget requests, among other things, 
  $72.6 million in the FY2020 Research, Development, Test, and Evaluation, 
Defense-Wide (RDT&EDW) account for Program Element (PE) 1160483BB,37 
maritime systems (line 263 in the FY2020 RDT&EDW account), including $45.2 
million for Project S0417: Underwater Systems, and $27.4 million for S1684: 
Surface Craft; and 
  $59.0 million in the FY2020 Procurement, Defense-Wide (PDW) appropriation

Potential Oversight Issues for Congress 
Degree of Emphasis on IW in Navy Budgets 
One potential oversight issue for Congress concerns how much emphasis to place on IW activities 
in Navy budgets, particularly in a context of constraints on Navy budgets and Navy desires to 
devote resources to developing “high end” combat capabilities for countering improved 
conventional military capabilities of countries such as China and Russia.38 Although the Navy, as

Navy Irregular Warfare and Counterterrorism Operations 
 
discussed earlier in this report, took actions in the years following the terrorist attacks of 
September 11, 2001, that were intended to improve its IW capabilities, the Navy in more recent 
years has taken other actions that might be viewed as reflecting a reduced Navy emphasis on IW. 
In that connection, the following points were provided to CRS by the Joint Staff J-7 Irregular 
Warfare office in August 2016: 
  “US Navy IW funding and force structure have declined over the last few years.” 
  “NIWO’s responsibilities now belong to OPNAV N515 [i.e., the office within the 
Chief of Naval Operations that oversees the NWG], with dedicated IW staff 
decreasing from 13 government/military personnel along with 6 contractors led 
by a RDML [rear admiral] to 2 contractors and one O-5 [an officer that in the 
Navy is a commander] under O-6 [an officer that in the Navy is a captain] 
oversight.” 
  In May 2014, the Navy closed its Maritime Civil Affairs and Security Training 
Command (MCAST), an action “which reduced civil affairs (CA) and security 
force assistance (SFA) capacity. The MCAST’s mission was to train sailors to 
perform civil-military affairs and security force assistance missions. It also 
provided approximately 50 percent of Navy expeditionary training.... MCAST 
functions are now distributed across the Navy. The Naval Education and Training 
Security Assistance Field Activity serves as the focal point for security assistance 
training issues. The Expeditionary Combat Readiness Center processes individual 
augmentees for deployment. Civil affairs functions were not replaced.” A July 
2015 Navy memo states “that the Navy does not ‘possess dedicated CA units or 
members.’” 
  The Navy’s FY2017 budget requested funding to preserve Helicopter Sea 
Combat (HSC) Squadron 85, a unit that “supports Naval Special Warfare and 
other SOCOM [Special Operations Command] assets,” which was “a positive 
development.” On the other hand, the Navy in March 2016 “disbanded HSC 84, a 
sister squadron providing similar support.... This action essentially cut 
experienced, operational capacity in half. Whether the TSUs [i.e., the two 
Tactical Support Units that are to be stood up under the Navy’s proposed FY2017 
budget] will meet SOF requirements remains to be seen.” 
  The Navy Community of Interest (COI) for Countering Irregular Challenges 
“does not extend beyond the Navy Analytic Group. This body, tied to the 
Community of Interest, submits IW program gap, technical demonstration, and 
study initiatives to N515 for funding. Members include Fleet Forces Command, 
the NECC, the Navy Undersea Warfare Center, and the Navy War College. The 
larger COI has not [as of August 2016] had a formal meeting in approximately 3 
years.”39 
A January 17, 2019, press report stated: 
After spending the better part of the past two decades supporting wars in a desert region, 
the  U.S.  Navy  is  starting  to  bring  the  SEALs  back  into  the  fold  as  it  faces  threats  from 
major powers such as China and Russia.

Navy Irregular Warfare and Counterterrorism Operations 
 
The  Navy  is  incorporating  its  elite  special  warfare  teams  into  strategic  calculations  for 
every potential  major power combat scenario, from China  and Russia to Iran and North 
Korea,  said  Vice  Chief  of  Naval  Operations  Adm.  Bill  Moran  in  a  round-table  with 
reporters at the Surface Navy Association’s annual symposium. 
The movement toward reconnecting with the blue water force (the Navy’s regular ships, 
aircraft and submarine forces) started under former Naval Special Warfare Command head 
Rear  Adm.  Brian  Losey,  who  retired  in  2016.  The  effort  has  continued  to  grow  under 
subsequent commanders, said Moran. 
“It’s to the point now where we include them in all of our exercises, our war games, our 
tabletops — because as much as it is their chance to ‘re-blue,’ it’s our chance to reconnect 
from the blue side," he added. “We’ve grown used to not having them in a lot of those 
situations. Now as  we’ve done  the  tabletops, the exercises  and the  war  games,  we see: 
‘Wow,  there  is  some  great  capability  here  that  can  set  the  conditions  for  the  kind  of 
operations in every single one of those campaigns.’ And that will continue to grow, I think.” 
There have been indications that the SEALs are specifically eyeing environments similar 
to  those  in  the  South  China  Sea.  A  recent  environmental  assessment  obtained  by  the 
Honolulu  Star  Advertiser  revealed  that  the  SEALs  were  looking  to  triple  the  amount  of 
training time  spent in the Hawaiian islands, expanding from Oahu and Hawaii  island to 
Kauai, Maui, Molokai and Lanai.40 
A January 30, 2019, press report similarly stated: 
Having spent 17 years conducting counterinsurgency and counterterrorism operations in 
the  deserts  and  mountains  of  the  Middle  East,  the  Naval  Special  Warfare  community  is 
shifting its focus to threats from China, Russia and aspiring adversaries. 
Navy  operations  planners  are  including  Navy  SEALs  in  all  aspects  of  planning  and 
training,  such  as  war  games,  exercises  and  tabletop  scenarios,  Vice  Chief  of  Naval 
Operations  Adm.  Bill  Moran  told  reporters  Jan.  16  at  the  Surface  Navy  Association's 
annual conference. 
The shift began in 2013 when Rear Adm. Brian Losey, then-commander of Naval Special 
Warfare Command, began  making "a concerted effort to talk to  his teams about getting 
back to the 'blue side,'" Moran said, referring to the Navy's large fighting forces of ships, 
submarines and aircraft. 
That focus has continued since Losey retired in 2016, Moran added. 
"[Losey]  saw  the  'great  power  competition,'  he  saw  the  threats  of  an  emerging  Russia, 
China, North Korea and  Iran," Moran said. [SEALs] have a very specific and important 
role to play in all situations." 
Since the U.S. insertion into Afghanistan in 2001, special operations forces, including the 
SEALs, have focused on a specific selection of their skill sets, including small-scale strikes 
and offensive actions, counterinsurgency, hostage rescue, counterterrorism and countering 
weapons of mass destruction. 
But these forces have other expertise that is relevant to both large-scale military conflicts 
as  well  as  the  type  of  posturing  and  competing  for  regional  and  global  dominance  that 
currently  is  happening,  according  to  a  2017  report  by  David  Broyles  and  Brody 
Blankenship, analysts at CNA, an Arlington, Virginia-based think tank that concentrates 
on the U.S. Navy.

News, January 17, 2019.

Navy Irregular Warfare and Counterterrorism Operations 
 
Those  skills  include  preparing  an  environment  for  operations,  reconnaissance, 
unconventional  operations,  military  information  support  operations  and  foreign 
humanitarian assistance, according to the report, The Role of Special Operations Forces in 
Global Competition. 
"Special operations forces have a greater role to play in today's global competition through 
a counteractive approach to adversary maneuvers," Broyles and Blankenship wrote. "The 
United States has only recently recognized that adversaries are exploiting the U.S. view of 
'preparing for future war' vice 'competing in the here and now.' " 
Moran agreed that Navy SEALs have a unique talent set that the "blue side" had largely 
forgotten. 
"We've grown used to not having them in a lot of situations. ... Wow, there are some great 
capabilities here that can set the conditions in the world for the kind of operations we are 
going to need in every single one of our campaigns," he said. 
A  draft  environmental  assessment  published  by  the  Navy  on  Nov.  8  indicated  that  the 
SEALs  are  planning  to  increase  training  in  Hawaii,  asking  to  increase  the  number  of 
exercises from the 110 events allowed now on non-federally owned land to as many as 330 
training  events  on  non-federal  land  or  waterways  and  265  training  events  on  federal 
property. 
The  proposed  training  also  would  expand  the  area  for  conducting  exercises  to  include 
Kauai, Lanai, Maui and Molokai, in addition to Oahu and Hawaii. 
The training, in a location relatively near to and similar in climate to the South China Sea, 
where China continues to assert its dominance, is necessary to enhance the Navy Special 
Warfare Command's traditional skill sets, including diving and swimming; operating with 
submersibles and unmanned aircraft systems; insertion and extraction; reconnaissance and 
parachuting; and rope suspension training activities, according to the report. 
Moran said the SEALs' return to their roots will bolster lethality of the Navy as a whole. 
"As much as it's their chance to re-blue, it's our chance to reconnect from the blue side," he 
said. "That will continue to grow, I think."41 
Potential oversight questions for Congress include the following: 
  How do current Navy IW capabilities and capacity compare with those of 5 or 10 
years ago? Under proposed Navy budgets, how will Navy IW capabilities and 
capacity in coming years compare to those of today? 
  In a context of constraints on Navy budgets and Navy desires to devote resources 
to developing “high end” combat capabilities for countering improved 
conventional military capabilities of countries such as China and Russia, is the 
Navy striking the right balance between funding for IW capabilities and capacity 
and funding for other Navy priorities? 
  Does Congress have sufficient visibility into the operations of U.S. SOF, 
including Navy SEALs, to support congressional oversight over those 
operations?42

Navy Irregular Warfare and Counterterrorism Operations 
 
Role of Naval Special Warfare Development Group (Seal Team 6) 
Another potential oversight issue for Congress concerns the role of Seal Team 6 in Navy CT and 
IW operations. A June 6, 2015, press report states the following: 
They  have  plotted  deadly  missions  from  secret  bases  in  the  badlands  of  Somalia.  In 
Afghanistan, they have engaged in combat so intimate that they have emerged soaked in 
blood that was not their own. On clandestine raids in the dead of the night, their weapons 
of choice have ranged from customized carbines to primeval tomahawks. 
Around the world, they have run spying stations disguised as commercial boats, posed as 
civilian  employees  of  front  companies  and  operated  undercover  at  embassies  as  male-
female pairs, tracking those the United States wants to kill or capture. 
Those operations are part of the hidden history of the Navy’s SEAL Team 6, one of the 
nation’s most mythologized, most secretive and least scrutinized military organizations. 
Once  a  small  group  reserved  for  specialized  but  rare  missions,  the  unit  best  known  for 
killing Osama bin  Laden  has  been transformed by  more than a decade of combat into a 
global manhunting machine. 
That  role  reflects  America’s  new  way of  war, in  which conflict is distinguished  not by 
battlefield wins and losses, but by the relentless killing of suspected militants. 
Almost everything about SEAL Team 6, a classified Special Operations unit, is shrouded 
in secrecy—the Pentagon does not even publicly acknowledge that name—though some 
of  its  exploits  have  emerged  in  largely  admiring  accounts  in  recent  years.  But  an 
examination  of  Team  6’s  evolution,  drawn  from  dozens  of  interviews  with  current  and 
former  team  members,  other  military  officials  and  reviews  of  government  documents, 
reveals a far more complex, provocative tale. 
While  fighting  grinding  wars  of  attrition  in  Afghanistan  and  Iraq,  Team  6  performed 
missions elsewhere that blurred the traditional lines between soldier and spy. The team’s 
sniper  unit  was  remade  to  carry  out  clandestine  intelligence  operations,  and  the  SEALs 
joined Central Intelligence Agency operatives in an initiative called the Omega Program, 
which offered greater latitude in hunting adversaries. 
Team  6  has  successfully  carried  out  thousands  of  dangerous  raids  that  military  leaders 
credit  with  weakening  militant  networks,  but  its  activities  have  also  spurred  recurring 
concerns about excessive killing and civilian deaths.... 
When suspicions have been raised about misconduct, outside oversight has been limited. 
Joint Special Operations Command, which oversees SEAL Team 6 missions, conducted its 
own  inquiries  into  more  than  a  half-dozen  episodes,  but  seldom  referred  them  to  Navy 
investigators. “JSOC investigates JSOC, and that’s part of the problem,” said one former 
senior military officer experienced in special operations, who like many others interviewed 
for  this  article  spoke  on  the  condition  of  anonymity  because  Team  6’s  activities  are 
classified. 
Even the military’s civilian overseers do not regularly examine the unit’s operations. “This 
is an area where Congress notoriously doesn’t want to know too much,” said Harold Koh, 
the  State  Department’s  former  top  legal  adviser,  who  provided  guidance  to  the  Obama 
administration on clandestine war.... 
Like  the  C.I.A.’s  campaign  of  drone  strikes,  Special  Operations  missions  offer  policy 
makers  an  alternative  to  costly  wars  of  occupation.  But  the  bulwark  of  secrecy  around 
Team 6 makes it impossible to fully assess its record and the consequences of its actions, 
including civilian casualties or the deep resentment inside the countries where its members

operate.  The  missions  have  become  embedded  in  American  combat  with  little  public 
discussion or debate.43

Appendix A. April 2018 Navy and Marine Corps 
Testimony on Special Operations Forces 
This appendix reprints the prepared statements of Rear Admiral Tim Szymanski, U.S. Navy, 
Commander, Naval Warfare Special Warfare Command, and Major General Carl E. Mundy, III, 
U.S. Marine Corps, Commander, U.S. Marine Corps Forces Special Operations Command, for an 
April 11, 2018, hearing the Special Operations Command’s efforts to transform the force for 
future security challenges. 
Prepared Statement of Rear Admiral Szymanski 
The text of Admiral Szymanski’s statement is as follows: 
Chairwoman  Ernst,  Ranking  Member  Heinrich  and  distinguished  Members  of  the 
Committee, I am honored to appear before you, and proud to provide an update on your 
Navy’s Special Operations Force and the U.S. Special Operations Command’s maritime 
component. 
As you are aware, the security challenges facing our nation today are numerous, and are 
made more difficult by adversaries who are exploiting emerging technologies and gaining 
ground.  We  will  continue  to  face  Violent  Extremist  Organizations  (VEOs),  while  the 
battlefield  expands  and  becomes  more  complex  and  chaotic.  Today,  our  most  pressing 
security  concerns  involve  the  aggressive,  coercive,  and  disruptive  actions  of  near-peer 
competitors  and  rogue  regimes.  Exerting  power  by  fighting  below  the  level  of  armed 
conflict favors these players to the point that they are gaining advantages that threaten our 
national security. We must continue to be smarter, stronger, quicker, and more lethal than 
our adversaries, in order to protect our nation in a world that grows more complex every 
day. 
As  an  enterprise  of  nearly  10,000  personnel—2,810  SEALs;  780  Special  Warfare 
Combatant-craft Crewmen; 4,100 support personnel; 780 reservists; 1,240 civilians—your 
Naval  Special  Warfare  (NSW)  Command  accounts  for  only  2.4  percent  of  the  Navy’s 
personnel. Our budget accounts for less than one percent of the Department of the Navy’s 
budget, and approximately 12 percent of U.S. Special Operations Command (USSOCOM) 
budget. 
We continue to have a global presence—operating in more than 35 countries on any given 
day. We are networked with the U.S. Navy and Joint Forces, the interagency, and allies 
and  foreign  partners,  executing  missions  in  support  of  USSOCOM,  the  U.S.  Navy, 
geographic Combatant Commanders, and ultimately, national objectives across a full range 
of political and operational environments. 
NSW’s ALIGNMENT TO THE NATIONAL DEFENSE STRATEGY 
The National Defense Strategy (NDS) published earlier this year charged the Department 
of Defense (DoD) to be more agile, more lethal, and more innovative in order to maintain 
our competitive advantage. The Chief of Naval Operations, in turn, laid out the maritime 
responsibilities  articulated  in  the  NDS,  focusing  on  increasing  Naval  Power  through 
balancing capability and capacity with readiness and sustainment. 
As  the  Commander,  my  challenge  is  to  man,  train,  and  equip  the  Force  to  be  better 
positioned to support the NDS, the National Military Strategy and the Navy’s Strategy for 
Maintaining  Maritime  Superiority,  while  supporting  the  operational  requirements  of  the 
theater  commanders.  Furthermore,  the  long-term  sustainment,  health,  and  well-being  of 
our people remains my highest priority.

NSW RESOURCING 
After nearly 17 years of war in Afghanistan and Iraq, we are focused on reasserting our 
capabilities as the maritime component to Special Operations, properly postured to meet 
the  threats  of  the  future,  enhancing  our  partnership  with  the  Navy  and  exploring 
opportunities for increased integration and interoperability, while building capabilities and 
capacity with fleet, submarine, aviation and cyber forces. 
Acknowledging that manpower requirements have outpaced authorized and actual growth, 
we have spent the last year taking a hard look at our force structure to determine how we 
can best use the resources we have to optimize the impacts we are making on the battlefield. 
We looked at how to eliminate redundancy, redirect resources and merge assets to build 
depth  and  agility  and  how  to  meet  transregional  threats  and  provide  increased  combat 
lethality to the Theater Special Operation Commands. Optimizing our Force is paramount 
to  meeting  current  operational  requirements  and  provide  greater  agility  to  meet  future 
requirements. 
We recently collaborated with the Naval Post graduate school to conduct a maritime, multi-
thread experiment in Southern California. The exercise allowed us to explore a realistic 
scenario using unmanned systems in a multi-domain (sea, air and land) environment. We 
learned a lot and advanced the potential use of artificial intelligence and human-machine 
teaming  in  current  conflicts  which  will  eventually  increase  our  lethality  while  reducing 
risk. 
We have made necessary investments aimed at increasing our lethality, and refining our 
capabilities that enable access to contested areas. 
We  have  made  significant  increases  in  our  unmanned  aerial  vehicle  lethality  by  adding 
targeting  capabilities,  increasing  the  capabilities  of  current  sensor  suites,  and  using 
algorithms and artificial intelligence to speed up the targeting cycle. 
We have modernized numerous small arms systems, including procuring a purpose built, 
full-time suppressed,  medium range  weapons system; a lighter  weight  medium  machine 
gun that matches and, in some cases, surpasses the effective range of a .50 caliber machine 
gun;  a  sniper  weapons  system  with  optics  and  wind  sensing  technology;  and  shoulder-
launched munitions that allow for very precise engagements through hardened structures. 
We have made great strides in modernizing our maritime mobility platforms. In fact, our 
partnerships with maritime industries has never been stronger. 
We have introduced high performance surface combatant craft into our fleet to serve across 
the spectrum of maritime operations. They include our new Combatant Craft Assault which 
replaced the NSW 11-meter rigid-hull inflatable boat and our Combatant Craft Medium 
which  replaced  the  Mark  V  Special  Operations  Craft  and  the  introduction  of  the  new 
Combatant Craft Heavy. 
Special  Operations  Force  (SOF)  undersea  mobility  platforms  provide  uniquely  capable, 
clandestine means to access peer/near-peer locations. To that end, we expect to introduce 
two  new  undersea  submersibles  this  year–  the  Shallow  Water  Combat  Submersible 
(SWCS),  which  will  replace  our  legacy  SEAL  Delivery  Vehicle  (SDV),  and  the  Dry 
Combat Submersible (DCS), a new platform to our inventory. 
Nearly  a  year  ago,  we  piloted  a  deliberate  effort  to  realize  the  Secretary  of  Defense’s 
guidance  of  exploiting  Industry’s  investment  in  technology  to  relentlessly  pursue 
innovative  and  advanced  operational  capabilities  for  our  warfighters  at  a  greater  speed, 
relevant to the pace of technology in order to outpace our adversaries. This venture allowed 
us to understand and take advantage of new DoD contracting and procurement authorities 
as  well  as  maximizing  the  utilization  of  DoD  and  USSOCOM  outreach-to-industry 
platforms such as Defense Innovation Unit Experimental (DIUx) and SOFWERX.

NSW  has  learned  and  applied  how  to  effectively  make  use  of  these  and  other  new  and 
emerging opportunities to rapidly bring future operational concepts to the present: such as 
our realization of Artificial Intelligence-Autonomy of ISR Drones. This example among 
others, show promise to have exponential impacts on our capabilities to accomplish our 
mission in a more agile, lethal and sustainable manner. Our efforts—to rapidly prototype, 
experiment  with  and  lead  in  new  and  emerging  technologies  are  aimed  at  delivering 
capabilities at the speed of relevancy to our warfighters. 
Finally, bottom up, operator-inspired innovation drives experimentation during exercises, 
and training eventually equates to relevancy and leads to greater success on the battlefield. 
With our component partners and throughout USSOCOM, innovation is happening at the 
unit level up and through headquarters. Our focus on innovation is driven by our people – 
buying down risk to our force while increasing our speed, accuracy, and lethality. 
PEOPLE: THE FIRST SOF TRUTH 
Our primary weapons system remains The Operator. We continue to invest heavily in our 
personnel,  whether  it’s  to  train,  retain  or  sustain  them.  We  select,  train  and  maintain 
persons  of  character,  who  are  mature,  highly  skilled,  culturally  attuned  and  trusted  to 
execute our nation’s most sensitive missions. 
Thank you for your role in the preservation of our Force with the 10-year, $1 billion Silver 
Strand  Training  Center-South,  the  single  most  important  military  construction  effort 
impacting the current and future operational readiness of the NSW Force. Once complete, 
the  complex  will  consolidate  the  training  requirements  of  today’s  force,  creating 
efficiencies and synergy of improved operational planning and preparedness, but also allow 
our operators to spend more time with their families and communities. 
We  remain  committed  to  the  physical  and  mental  health  of  our  operators,  as  we  have  a 
moral obligation to ensure their  well-being. Preservation of the Force and Families, our 
Human  Performance  Program,  and  our  most  important  initiatives  involving  Cognitive 
Health are about keeping our warriors in the fight, extending their service life, and giving 
them a high quality life post-service. 
With strong Congressional support, the USSOCOM Preservation of the Force and Family 
program continues to meet and exceed the intent to build resilience and facilitate the long-
term care of our operators and their families, while never forgetting our fallen teammates 
with ongoing support to our Gold Star Families. 
Embedded professional care providers working within validated programs have helped turn 
the corner on many of the negative trends that have impacted those who have been in this 
long fight. Our usage data shows an increase in service members and families going to see 
clinical psychologists, licensed clinical social workers, nurse case managers, which speaks 
directly to de-stigmatization and trust. Similarly, there is a high number of cross referrals 
among the various care providers that demonstrates mutual support and clinical trust and 
reliance. 
In  regard  to  Human  Performance,  our  athletic  trainers,  strength  coaches  and  physical 
therapists  provide  tailored  and  operationally  relevant  programs  have  resulted  in  injury 
reduction and increased recovery time from injuries with a direct impact to overall team 
readiness. 
Our Warrior and Family Support staff provide hands on, personal touch and connection to 
our  families  and  children,  connecting  them  to  all  the  Service-provided  and  SOF-unique 
programs that are so vital to the strength and resilience of our family members. 
We have also learned that long-term physical and psychological challenges may result in 
impacts  to  one’s  memory,  attention,  processing  speed,  problem-solving,  visuospatial 
function  and  impulse  control  which  can  affect  operational  performance  and  mission

accomplishment. Given that we are in the longest continuous stretch of armed conflict in 
our history, learning about the cognitive health of our force is a critical initiative. 
We  have  initiated  a  Cognitive  Surveillance  Program  that  will  be  a  more  pre-emptive 
approach  to  intervention  where  cognitive  impacts  are  indicated.  More  broadly,  this 
initiative  will  seek  to  identify  injuries  earlier,  track  individual  trends,  and  assist  in 
developing comprehensive treatment plans to aid in the recovery of our service members. 
The end-state is to get NSW operators back into the fight while contributing to their long-
term wellness. 
The  Surveillance  Program  entails  an  initial  baseline  screening  of  all  SEAL/SWCC 
operators within NSW by 30 June 2018; and ongoing re-testing every two years to assess 
significant change, similar to other routine exams such as dental or audiogram. 
Aggressive  efforts  include  increasing  awareness  of  potential  issues  and  not  waiting  for 
perfect  solutions.  Therefore,  we  are  actively  ‘driving  the  science’  through  our  blast 
exposure research efforts, ultimately looking to create a ‘dive-table-like’ approach to heavy 
weapons/breaching exposure levels and mitigation needs. 
NSW  continues  to  seek  and  offer  best  practices  as  we  develop  our  cognitive  health 
emphases. We rely on education, informed research efforts, and leadership support across 
the continuum of care to help  mitigate the range of brain injuries and increase recovery 
rates for our members. 
Part of that continuum of care focuses on our transitioning veterans, whether at four years 
or after forty, with a holistic, SOF-unique initiative called Future Former Frogmen, or F3. 
F3  focuses  on  ensuring  the  successful  transition  of  our  active  duty  into  civilian  life  by 
leveraging  our  neurocognitive  science  initiatives,  continuum  of  leadership  development 
efforts, readiness support programs, and veteran’s resources. F3 provides structure, process 
and  guidance  throughout  the  complex  transition  experience  giving  the  service  member 
access  to  existing  programs  to  ensure  NSW  veterans  remain  resilient.  SOF  for  Life,  a 
powerful support network, continues from active duty life to veteran life. 
Today in Coronado, California, at the Basic Underwater and Demolition / SEAL school, 
otherwise known as BUD/S, there are approximately 100 of America’s best and brightest 
going through training to be part of the Navy’s elite special operations maritime force as 
part of the most recent class, Class 330. 
Just like those seeking to be part of my brethren’s communities, those seeking to be part of 
the SEAL community, those who succeed in the 63-week course will earn their Trident. 
At the end of 63 weeks, each student will have swam 48 miles; hiked or patrolled over 150 
miles; and conducted at least 40 dives while spending a minimum of 60 hours, or two and 
a half days under water. As a class, at the end of those 63 weeks, they will have completed 
the equivalent of swimming from Cuba to the southern tip of Florida, then running to New 
York City. 
And that is just a snapshot of what we ask them to do before they have taken their first step 
into their first operation in defense of our country. It is precisely because of what we ask 
them to do, starting in Coronado, then around the world, through operation after operation, 
that we are focused on their long-term health, and the well-being of our Force and Families. 
Naval  Special  Warfare  Command  will  continue  to  place  priority  on  strengthening, 
equipping  and  protecting  our  people;  outpacing  our  enemies  in  the  employment  of  new 
technologies  and  accelerating  trends,  enabling  us  to  compete  below  the  threshold  of 
conflict.  We  will  refine  and  adapt  our  organizational  structure  to  ensure  Naval  Special 
Warfare remains relevant and lethal, and when necessary, stands ready, willing and able to 
engage in combat to fight and win decisively for many years to come.

Prepared Statement of Major General Mundy 
The text of Major General Mundy’s statement is as follows: 
Introduction 
Marine  Raiders are  the  Marine  Corps’ contribution to United States Special Operations 
Command  (USSOCOM).  Through  specialized  and  advanced  training,  MARSOC  builds 
upon its unique attributes and ethos as Marines to produce agile, scalable, fully-enabled, 
and  responsive  special  operations  forces  (SOF)  comprised  of  operators  and  special 
operations-specific  combat  support  and  combat  service  support  specialists.  MARSOC 
formations task organize for every assigned mission and leverage their robust command 
and control capability and their ability to fuse operations with intelligence down to the team 
level. All of these factors enable our Raiders to succeed in distributed environments and 
enable partners at the tactical and operational levels of war. MARSOC contributes to the 
SOF enterprise and US combatant commands by providing full spectrum special operations 
capabilities to combat complex transregional problems. 
Established in 2006, our organization continues to address the most immediate threats to 
our Nation and has become a key participant in the ongoing fight against violent extremist 
organizations.  Accepting  this,  we  are  also  cognizant  that  we  must  work  to  minimize 
pressure on our force and our families as we simultaneously prepare for future threats. We 
ensure  preparedness  by  adapting  our  training  methods  using  feedback  from  currently 
deployed forces to better prepare our Raiders for what they will encounter while deployed. 
Simultaneously,  we  minimize  pressure  on  the  force  by  ensuring  adequate  access  to 
Preservation  of  the  Force  and  Families  (POTFF)  resources.  We  recognize  that  our 
operational  capability  ultimately  rests  upon  a  foundation  of  outstanding  individuals  and 
their  families.  In  order  to  safeguard  and  sustain  MARSOC’s  human  capital,  our  most 
valuable  resource,  we  continually  strive  to  balance  operational  commitments  with  time 
Raiders spend at home station. Part of our effort to take care of families involves ensuring 
that  our  POTFF  program  not  only  delivers  responsive  and  effective  support,  but  that  it 
continues to evolve with changing demands and needs of our force. 
Background 
During my tenure as the Commander of MARSOC, I have continually been impressed by 
the caliber of our individuals, be they Marines, Sailors, or civilians. They are well trained, 
well equipped, and provide the full spectrum  special operations capability that has been 
crucial to success on the modern battlefield in places as diverse as Mali in West Africa, 
contested  areas  of  Iraq,  and  Marawi  in  the  Philippines.  Twelve  years  on,  MARSOC  is 
maturing  into  a  full  and  integral  member  of  the  SOF  enterprise  just  as  it  continues  to 
provide Raiders to counter our Nation’s threats. Taking into account where MARSOC is 
today, we would be remiss if we did not acknowledge some of the formative episodes in 
the history of our Marine Corps that got us here. 
The  United States  Marines Corps’ rich  history is one  that  is replete  with expeditionary 
operations  against  what  we  know  today  as  irregular  threats.  These  actions  serve  as  the 
foundation for what is Marine Corps Special Operations today. Although the United States 
Marine Corps (USMC) did not provide a service component to the United States Special 
Operations  Command  (USSOCOM)  until  2005,  the  Marine  Corps  has  demonstrated  an 
ability to conduct and support special operations throughout its history. 
                                                 
45 Statement of Rear Admiral Tim Szymanski, U.S. Navy, Commander, Naval Special Warfare Command, before the 
Senate Armed Services Committee subcommittee on Emerging Threats and Capabilities, April 11, 2018, 9 pp. 
Congressional Research Service

Navy Irregular Warfare and Counterterrorism Operations 
 
In the early years of America’s involvement in World War II, President Franklin Delano 
Roosevelt was determined to bring the war to our enemies as rapidly as possible. Because 
of  the  Marine  Corps’  historical  successes  in  small  wars  and  its  recent  development  of 
amphibious operational concepts, it was considered to be the ideal parent organization for 
the president’s vision for “commando” operations. 
In  January  1942  the  United  States  Marine  Corps  established  two  Raider  battalions.  The 
mission of the new Raider units was to spearhead amphibious landings, conduct raiding 
expeditions  against  Japanese  held  territory,  as  well  as  conduct  guerilla-type  operations 
behind  enemy  lines  for  extended  periods.  Marine  Raiders  were  intellectually  dynamic, 
morally disciplined, and physically fit with an irrepressible sense of duty, loyalty to one 
another,  and  imbued  with  a  “Gung  Ho”  spirit  in  the  face  of  adversity…  much  like  the 
Marines and Sailors we select and train as Raiders today. 
During  the  Vietnam  War  and  throughout  the  Cold  War  era,  the  Marine  Corps  did  not 
formally possess a specialized unit. However, many Marines were members of specialized 
Joint  and  certain,  tailored  conventional  units,  such  as  force  reconnaissance  and  Marine 
Expeditionary  Units  (Special  Operations  Capable).  These  units  performed  some  of  the 
types  of  missions  we  associate  with  Special  Operations  today.  The  complex  global 
environment produced by the end of the Cold War as well as the world changing events of 
September 11, 2001, prompted an almost immediate need for additional special operations 
capacity capable of achieving operational and strategic effects. In light of these events and 
the  pressing  need  for  more  SOF,  Secretary  of  Defense  Donald  Rumsfeld  called  for  the 
Marines to work more closely with USSOCOM. 
After  validating an initial proof of concept in 2004 known as the Marine Corps Special 
Operations  Command  Detachment  (DET  One),  the  Secretary  of  Defense  directed  the 
Marine Corps to provide a permanent contribution to USSOCOM  – what would become 
Marine Corps Forces, Special Operations Command – in November 2005. On 24 February 
2006,  MARSOC  activated  at  Camp  Lejeune,  North  Carolina  as  a  service  component 
assigned to  USSOCOM.  MARSOC today comprises a  headquarters, one Marine Raider 
Regiment, one Marine Raider Support Group, and the Marine Raider Training Center. The 
Command has forces on both the east coast at Camp Lejeune, North Carolina, and on the 
west coast at Camp Pendleton, California. Presiding over  a total force of approximately 
3,000 Marines, Sailors, and 200 Federal Civilians, the Command is employed across the 
globe  executing  special  operations  missions  in  support  of  SOCOM  and  the  geographic 
combatant commands that span the SOF core activities. With a focus on counterterrorism, 
direct  action,  special  reconnaissance,  foreign  internal  defense,  security  force  assistance, 
and  counterinsurgency,  your  modern-day  Raiders  also  have  the  capability  to  directly 
support  hostage  rescue  and  recovery,  countering  of  weapons  of  mass  destruction, 
unconventional  warfare,  foreign  humanitarian  assistance,  military  information,  and  civil 
affairs operations. In order to achieve success and provide full spectrum capability across 
this wide swathe of core activities, we must prioritize our efforts. 
MARSOC Priorities 
Understanding  our  role  as  a  force  provider  and  capability  generator  within  the  SOF 
enterprise, we have taken the SOCOM Commander’s priorities of “Win, Transform, and 
People,” and applied them to how we prepare our forces to accomplish assigned missions. 
To this end, MARSOC currently focuses on four priority areas: the provision of integrated 
full  spectrum  SOF,  capabilities  integration  between  SOF  and  Marine  Air  Ground  Task 
Forces (MAGTF), future force development, and the preservation of the force and families. 
Priority 1: Force Provider 
Our first priority is to provide integrated full spectrum SOF that are task organized, trained 
and equipped to accomplish assigned special operations tasks. At any given point in the 
year, MARSOC has approximately 400 Raiders deployed across 18 countries carrying out

assigned missions. We maintain three, forward task organized Marine Special Operations 
Companies; one each in Central Command, Africa Command, and the Pacific Command 
areas  of  responsibility.  In  addition  to  company-level  deployments,  we  maintain  one 
persistent  O-5  (Lieutenant  Colonel)  level  Special  Operations  Task  Force  in  Central 
Command and a one-third rotational split with Naval Special Warfare Command for an O-
6  (Colonel)  level  Combined/Joint  Special  Operations  Task  Force  Headquarters,  also  in 
Central Command. At every level, these deployed formations bring integrated capabilities 
across all functional areas and allow us to operate across the full range of special operations 
missions. We believe that it is these high-end capabilities that provide our forces with a 
competitive edge against the adversaries we face. 
Providing  our  force  begins  with  the  recruitment  process  and  continues  through  our 
assessment, selection, and individual training pipeline. We are focused on recruiting the 
best individuals from across the Marine Corps. Based on the results of our deployed forces 
and  feedback  from  supported  commanders,  our  recruiting  and  selection  methods  are 
working.  Our  training  is  progressive.  As  individuals  earn  new  special  operations 
specialties, they are moved to teams or special skills training environments. This training 
continues until deployment and covers everything from individual skill sets to high-end, 
advanced, complex unit collective training. 
In  order  to  assess  and  certify  Marine  Special  Operations  Companies  for  deployment, 
MARSOC  has  created  the  RAVEN  exercise.  Held  six  times  each  year,  RAVEN 
emphasizes realistic decision making for company and team commanders and provides a 
venue to practice the full planning, decision, execution, and assessment cycle. Alternating 
between Gulfport, Mississippi and Smyrna, Tennessee, RAVEN is a living exercise that 
enables MARSOC to incorporate the most current lessons from our deployed units as well 
as anticipated enemy actions inform and support ongoing joint contingency planning. For 
example, our most recent RAVEN conducted in Tennessee, featured a more robust foreign 
intelligence  threat  that  undertook  both  physical  and  technical  surveillance  against  our 
Marine Special Operations Teams. During this RAVEN we also exposed our teams to the 
degraded communications environment we would expect to encounter when facing a near-
peer/emerging competitor. 
The training environments we create are dynamic. Not only do they prepare our Raiders 
for the current operational challenge, but they also evolve based on emerging threats and 
our expected participation in support of standing operational plans. Another benefit of the 
RAVEN  exercises  is  its  utility  as  a  venue  for  integrating  conventional  Marine  Corps 
resources into what is otherwise a SOF-centric exercise. 
Priority  2:  Capabilities  Integration  with  MAGTFs  (Interoperability,  Integration,  and 
Interdependence) 
Second, we provide a bridge for routine capabilities integration with SOF and the deployed 
Marine Air Ground Task Forces to fully maximize the complimentary capabilities of each 
formation; especially in light of near-peer/emerging competitors. Given the threats present 
on contemporary battlefields and considering those we expect to face in the future, it has 
become  increasingly  important  for  SOF  to  be  able  to  integrate  “seamlessly”  with  the 
conventional forces and vice versa. Conventional forces offer capabilities and a capacity 
that simply do not exist in our small formations. In today’s complex operating environment, 
the extent to which we, across the Joint Force, are able to leverage one another’s strengths, 
and thereby offset our vulnerabilities, could determine the difference between success and 
failure. Cyber and space based capabilities, intelligence exploitation, mobility, fire support, 
logistics  and  medical  support,  are  all  examples  of  capabilities  that  we  partially  rely  on 
conventional forces to provide– especially in scenarios involving high intensity combat. 
Examples of interoperability and capabilities integration occur every day across the globe 
from  Syria  and  Iraq,  Afghanistan,  the  Philippines  and  remote  locations  in  Africa.  With 
Congressional Research Service  
 
24 
Navy Irregular Warfare and Counterterrorism Operations 
 
deliberate efforts to participate in each other’s wargames, exercises, and training, we can 
institutionalize these efforts to the point that they become routine. 
Priority 3: Future Force Development 
As the operating environment evolves and more complex threats emerge, MARSOC must 
adapt  its  force  to  meet  these  new  challenges.  Constant  and  deliberate  innovation,  and 
evolution is critical to our success. Our concept for development is based on both a bottom-
up  driven  process  that  incorporates  immediate  battlefield  feedback  into  our  training 
curricula,  equipment  research,  testing,  procurement;  and  a  top-down  approach  that 
combines more traditional capability acquisition processes with longer-term future concept 
and wargaming efforts. 
Regarding equipment development and acquisition, we are tightly integrated with SOCOM 
and the Marine Corps and look forward to benefiting from the ongoing efforts of SOCOM’s 
Acquisition  Technology  &Logistics,  SOFWERX,  and  the  Marine  Corps’  Rapid 
Capabilities Office. All of these organizations offer us an expedited procurement process 
for emerging technology. We have already taken steps to bring our vision to fruition with 
regard to capability development in particular technology areas. These include freeze dried 
plasma, semi-autonomous seeing and sensing capability, organic precision fires, counter-
UAS  rapid  self-defense,  unmanned  cargo  UAS  and  ground  systems,  rapid  fusion  of  big 
data analytics and machine assisted learning, broadband tactical edge communications, and 
specialized insertion capabilities. As we research and improve our warfighting capabilities, 
we  must  kept  in  mind  that  our  near-peer/emerging  competitors  are  also  making  similar 
advances  and  investing  in  emerging  technology.  It  is  critical  that  we  ensure  that  the 
technological capabilities we opt for are able to operate, communicate, and self-heal in a 
signals degraded environment. 
Likewise  from a training perspective,  we recognize the  need to simulate operations in a 
degraded/denied  communications  environment  that  reflect  what  we  might  face  when 
confronting  near-peer/emerging  competitors.  We  also  plan  to  continue  to  improve  our 
proficiency in the critical combined arms skills that both increase our lethality and allow 
us  to  maintain  a  tactical  advantage  over  our  adversaries.  Last,  we  acknowledge  that  we 
must be able to operate in any clime and place, therefore we are committed to training in 
environments that replicate the full range of what we may experience on the battlefield. 
Complementing  our  near  and  mid-term  efforts  at  capability  development  is  longer  term 
work on the development of a MARSOC-specific futures concept. Although this concept 
bears a resemblance to similar initiatives undertaken  with the Department, it very  much 
reflects  MARSOC’s  unique  place  within  SOF  and  interpretation  of  what  the  future 
operating environment might look like. We see a world overwhelmingly influenced by a 
resurgence  of  regional  competition  and  instability.  As  these  two  themes  collide,  the 
complexity of the operating environment will dramatically challenge the ability of leaders 
at all levels to first, understand what is happening and, second, make sound decisions. This 
is the very situation in which Raider formations of the future must be prepared to operate; 
an urgent, volatile, complex, high-stakes problem that comprises multiple actors and defies 
the application of traditional US strengths and solutions. 
The results of our futures analysis, conducted over the past 18 months, have provided broad 
implications  for  the  force  as  well  as  options  which  MARSOC  can  use  to  shape  future 
capability to meet the challenges posed by the future operating environment. Throughout 
our internal wargame series, four discrete concepts or ‘themes’ consistently emerged. Each 
theme describes a distinct aspect of a vision for MARSOC, but at the same time each built 
upon the others such that the four are interconnected and mutually supporting. Together 
they provide a strong conceptual basis for a future MARSOC force that outpaces changes 
in the operating environment and remains a reliable force across warfighting and Title X 
functions. Collectively, these themes have come together to form the four, core pathways 
Congressional Research Service  
 
25 
Navy Irregular Warfare and Counterterrorism Operations 
 
of innovation: MARSOF as a Connector, Combined Arms for the Connected Arena, The 
Cognitive Operator, and Enterprise Level Agility. 
Our futures vision document, MARSOF 2030 explains each of these innovation pathways 
in depth and also explores how they interconnect with one another. I will briefly introduce 
them  here  for  the  benefit  of  the  committee.  ‘MARSOF  as  a  Connector’  is  intended  to 
capture MARSOC’s facility in building cohesive, task organized teams. It is the idea that 
MARSOC can be the ideal integrator and synchronizer of U.S. Governmental capabilities 
with USSOF and partner nation actions. It also acknowledges the non-military nature of 
many of the problems we face and the need to look beyond for more durable solutions that 
involve tools other than the military. 
‘Combined Arms for the Connected Arena’ aims to get at the requirement to ‘sense’ and 
‘make sense of’ what is happening in diverse and multi-dimensional environments. This 
second pathway also speaks to the  use  of cyber and information  ‘domains’ as potential 
venues  for  conflict  now,  but  certainly  with  increasing  relevance  as  we  look  toward  the 
future. From our standpoint, we must become as comfortable operating in these ‘virtual’ 
domains as we are in the physical. 
Perhaps  the  most  foundational  of  all  of  our  innovation  pathways  is  ‘the  Cognitive 
Operator’. This pathway touches all others. At its core is the idea that the future requires a 
SOF operator with an equal amount of brains to match the brawn; foresight in addition to 
fortitude.  Your  future  Raiders  must  preside  over  expanded  capabilities  that  include  the 
ability to influence allies and partners; understand complex problems; apply a broad set of 
national, theater, and interagency capabilities to those problems; and fight as adeptly in the 
virtual space as the physical. 
The last innovation pathway, ‘Enterprise Level Agility’, leverages MARSOC’s relatively 
small size as an advantage. MARSOC possesses the advantage of being a relatively small 
force with its own component headquarters – this allows the command to rapidly reorient 
the organization to confront new challenges as they emerge. In other words, MARSOC’s 
organizational  dexterity  can  provide  SOCOM  with  an  agile,  adaptable  force  to  meet 
unexpected  or  rapidly  changing  requirements.  In  this  context,  MARSOC’s  small  size 
becomes a strength; one that can provide both institutional and operational agility to the 
SOCOM Commander. 
Priority 4: Preservation of the Force and Families 
Calling to mind the SOF Truth that “people are more important than hardware,” our fourth 
priority is the preservation of our force and families program that provide our Raiders and 
their  families  with  the  access  to  resources  promoting  personal  resiliency  increasing 
longevity in service. Although listed as my fourth priority, preservation of the force and 
families is equally as important as the previous three priorities because people are at the 
heart of all we do. Currently, MARSOF special operators average 1 day overseas for every 
1.9 days at home. Our capability specialists that enable communications, intelligence, air 
support,  explosive  ordnance  disposal,  and  our  canine  handlers,  vary  by  occupational 
specialty but average between 1 to 1.7 and 1 to 1.2 days deployed as opposed to days spent 
at home station. What these numbers do not reflect is the additional time that is spent away 
from home while training in CONUS. Although difficult to measure, Personnel Tempo or 
PERSTEMPO receives significant attention at all leadership levels within the Command 
such  that  we  aim  to  balance  our  service  members’  schedules  between  training  at  and 
training away from home station. 
Because  of  this  high  operational  tempo,  POTFF  has  become  an  integral  tool  for 
maintaining the overall health of our force through programs that are focused on improving 
human  performance,  providing  resources  for  behavioral  health,  developing  spiritual 
fitness, and offering other family-oriented opportunities that are designed to strengthen the 
Congressional Research Service  
 
26 
Navy Irregular Warfare and Counterterrorism Operations 
 
family unit. We appreciate the continual support from Congress on providing the funding 
for programs and specialized capabilities to make these programs effective. 
Culture of accountability: 
Closely tied to these efforts, in concert with both SOCOM and the Marine Corps, is our 
command-wide push to enhance our culture of accountability as it relates to issues such as 
sexual  misconduct,  illicit  drug  use,  personal  accountability,  and  unauthorized  media 
release. As an example, our reported number of sexual assault cases remains in the low 
single  digits  and  we  have  not  had  any  victim  reported  incidents  in  Fiscal  Year  18.  We 
attribute this low number of incidents to our constant command level messaging campaign 
and  our  strong  Sexual  Assault  Prevention  and  Response  (SAPR)  program.  While  we 
believe that even a single incident is one too many, we continue to strive to eradicate sexual 
and other  forms of  misconduct  from our  force. We strive  each day to provide  you SOF 
personnel that continue to embody the values of accountability, integrity, and commitment 
in honorable service to our nation. 
Conclusion: 
In conclusion, I am committed to providing Marine Raiders that provide the nation with 
full spectrum special operations capability and whose actions continually demonstrate our 
motto of Spiritus Invictus, or ‘unconquerable spirit’. Your Marine Special Operators will 
remain always faithful, always forward. I thank the committee for your continued support 
of  our  military  members  and  their  families  and  also  for  your  commitment  to  national 
security.46

Appendix B. November 2011 Navy Testimony on 
Navy IW Activities 
This appendix presents the text of the Navy’s prepared statement for a November 3, 2011, hearing 
before the Emerging Threats and Capabilities subcommittee of the House Armed Services 
Committee on the IW activities of the military services. The text of the statement, by Rear 
Admiral Sinclair Harris, Director, Navy Irregular Warfare Office, is as follows: 
Chairman Thornberry, Congressman Langevin, and distinguished members of the House 
Armed Services Emerging Threats and Capabilities Subcommittee, it is an honor for me to 
be here with you today to address the U.S. Navy’s efforts to institutionalize and develop 
proficiency  in  irregular  warfare  mission  areas.  These  efforts  are  vital  to  our  national 
interests and, as part of a comprehensive approach for meeting complex global challenges, 
remain  relevant  in  a  time  of  uncertainty  and  constant  change.  To  meet  these  challenges 
Admiral Greenert, Chief of Naval Operations, recently provided his Sailing Directions to 
our Navy emphasizing the mission to deter aggression and, if deterrence fails, to win our 
Nation’s  wars.  Today,  the  Navy  is  engaged  around  the  world  conducting  preventive 
activities that stabilize, strengthen, and secure our partners and allies providing regional 
deterrence against state and non-state actors, while at the same time fighting, and winning, 
our  Nation’s  wars.  We  expect  the  demand  for  these  activities  to  increase  in  the  future 
security  environment  as  a  capacity  constrained  Navy  seeks  to  maintain  access  and 
presence.  Emphasis  on  increased  training  and  education  will  enable  our  continued 
readiness to effectively meet global demand. 
As demand for our Navy continues to grow, we continue to leverage our Maritime Strategy 
with our partners, the Marine Corps and Coast Guard. The maritime domain supports 90% 
of the world’s trade and provides offshore options to help friends in need, and to confront 
and defeat aggression far from our shores as part of a defense in depth approach to secure 
our  homeland.  CNO’s  Sailing  Directions,  coupled  with  an  enduring  Maritime  Strategy, 
underscore  the  Navy’s focus  on  multi-mission platforms and  highly  trained Sailors that 
conduct activities across the operational spectrum. Key tenets of the force are readiness to 
fight and win today while building the ability to win tomorrow; to provide offshore options 
to deter, influence, and win; and to harness the teamwork, talent and imagination of our 
diverse  force.  While  the  Maritime  Strategy  spans  the  spectrum  of  warfare,  the  Navy’s 
Vision  for  Confronting  Irregular  Challenges  (CIC),  released  in  January  2010,  addresses 
mission  areas  of  irregular  warfare  as  well  as  maritime  activities  to  prevent,  limit,  and 
interdict  irregular  threats  and  their  influence  on  regional  stability  through,  insurgency, 
crime, and violent extremism. 
The  CIC  Vision  is  derived  from  our  Maritime  Strategy  with  the  intention  to  implement 
steps  towards  increasing  the  Navy’s  proficiency  in  supporting  direct  and  indirect 
approaches  that  dissuade  and  defeat  irregular  actors  who  exploit  uncontrolled  or 
ungoverned spaces in order to employ informational, economic, technological, and kinetic 
means against civilian populations to achieve their objectives. The CIC Vision is guiding 
the alignment of organizations, investments, innovation, procedures, doctrine, and training 
needed  to  mainstream  CIC  capabilities  within  the  Fleet.  These  efforts  are  focused  on 
outcomes  of  increased  effectiveness  in  stabilizing  and  strengthening  regions,  enhancing 
regional  awareness,  increasing  regional  maritime  partner  capacity,  and  expanding 
coordination and interoperability with joint, interagency, and international partners. These 
outcomes support promoting regional security and stability and advancing the rule of law 
allowing good governance and promoting prosperity by helping partners better protect their 
people  and  resources.  In  addition  to  preventive  activities,  the  Vision  guides  efforts  to 
inhibit  the  spread  of  violent  extremism  and  illicit,  terrorist,  and  insurgent  activities.  To 
achieve  these  outcomes,  the  Navy  is  actively  reorienting  doctrine  and  operational

approaches,  rebalancing  investments  and  developmental  efforts,  and  refining  operations 
and partnerships to better support a comprehensive approach to U.S. efforts. These efforts 
will provide a Navy capable of confronting irregular challenges through a broad array of 
multi-mission  capabilities  and  a  force  proficient  in  the  CIC  missions  of  security  force 
assistance,  maritime  security,  stability  operations,  information  dominance,  and  force 
application necessary to support counterinsurgency, counterterrorism, and foreign internal 
defense missions. 
In line with its strategy for confronting irregular challenges the Navy has leveraged key 
force  providers,  such  as  the  Navy  Expeditionary  Combat  Command,  and  established 
Maritime  Partnership  Stations,  and  Maritime  Headquarters  with  Maritime  Operations 
Centers  to  meet  the  demands  and  missions  consistent  with  its  strategy  and  vision.  The 
evolution  of  intelligence  and  strike  capabilities  has  enabled  the  Navy  to  meet  urgent 
Combatant  Commander  requirements  for  counterterrorism  and  counterinsurgency 
operations and highlighted further opportunities for the Navy as an important joint partner. 
While these operational organizations and activities deliver Navy capabilities in theater, 
the Navy Irregular Warfare Office, established by the CNO in July 2008, has guided the 
implementation  and  institutionalization  of  the  CIC  Vision.  The  Navy  Irregular  Warfare 
Office,  working  closely  with  USSOCOM,  other  Combatant  Commanders,  Services, 
interagency  and  international  partners,  has  rapidly  identified  and  deployed  Navy 
capabilities  to  today’s  fight,  and  is  institutionalizing  confronting  irregular  challenges 
concepts in the Navy’s planning, investment, and capability development. 
The  Navy  Irregular  Warfare  Office  operates  under  three  primary  imperatives  consistent 
with  the  Maritime  Strategy,  CNO’s  Sailing  Directions,  and  the  Navy’s  Vision  for 
Confronting Irregular Challenges. They provide integration and institutionalization in CIC 
mission  areas  and  are;  (1)  improve  the  level  of  understanding  concerning  the  maritime 
contribution to the joint force; (2) increase proficiency of the whole of Navy to confront 
irregular  challenges;  and  (3)  drive  maritime  and  special  operations  forces  to  seamless 
integration in addressing irregular challenges. These three imperatives focus the Navy’s 
implementation efforts and mainstream the concept that preventing wars is as important as 
winning  them.  Our  Navy  must  be  ready  to  transition  seamlessly  between  operational 
environments, with the capability and training inherent in the Fleet. 
Department  of  Defense  Directive  3000.07  directs  the  services  to  “improve  DoD 
proficiency for irregular warfare, which also enhances its conduct of stability operations” 
and directs reporting to the Chairman of the Joint Chiefs of Staff annually. Navy efforts to 
institutionalize  and  provide  proficiency  in  confronting  irregular  challenges,  includes 
proficiency  in  irregular  warfare  missions  along  with  missions  of  maritime  security 
operations  and  information  dominance,  a  key  enabler  for  CIC.  Currently,  the  Navy 
leverages  its  access  and  persistent  presence  to  both  better  understand  and  respond  to 
irregular challenges and is actively evolving its proficiency to prevent and counter irregular 
threats  while  maintaining  its  ability  to  conduct  the  full  spectrum  of  naval  warfare.  Its 
access,  presence,  and  emphasis  on  maritime  partnerships  enable  broader  government 
efforts  to  address  underlying  conditions  of  instability  that  enhance  regional  security. 
Through its mix of multi-mission capabilities, the Navy provides political leaders with a 
range  of  offshore  options  for  limiting  regional  conflict  through  assurance,  deterrence, 
escalation and de-escalation, gaining and maintaining access, and rapid crisis response. In 
addition  to  its  inherent  ability  to  protect  the  maritime  commons,  its  effectiveness  in 
building maritime partner capability and capacity contributes to achieving partner security 
and  economic  objectives.  Operating  in  and  from  the  maritime  domain  with  joint  and 
international partners, the Navy is enhancing regional security while dissuading, deterring, 
and when necessary, defeating irregular threats. 
The Navy acknowledges the complexity of the future security environment and continues 
to explore balanced approaches. Following are the Navy’s current focus areas: 
Congressional Research Service  
 
29 
Navy Irregular Warfare and Counterterrorism Operations 
 
Fleet-SOF  Integration:  Navy’s  afloat  basing  support  to  special  operations  forces  has 
extended  their  reach  into  denied  or  semi-permissive  areas  enabling  highly  successful 
counterterrorism  missions.  Navy  provides  inherent  combat  capabilities,  multi-mission 
ships  and  submarines  collecting  mission  critical  information,  approval  for  1052  support 
billets for Naval Special Warfare, two dedicated HCS squadrons, and shipboard controlled 
UAV orbits supporting counterterrorism operations. The Navy is aligned to improve this 
integration  through  pre-deployment  training,  mission  rehearsals,  improvements  to  fleet 
bandwidth  allocation,  shipboard  C4I  enhancements,  and  C2  relationships  needed  to 
prosecute time sensitive targets. 
Maritime Partnerships: Establishing enduring maritime partnerships is a long-term strategy 
for securing the maritime commons. Legal, jurisdictional, and diplomatic considerations 
often complicate efforts to secure the maritime commons, especially from exploitation by 
highly  adaptive  irregular  actors.  In  recognition  of  these  considerations,  the  Navy  is 
emphasizing  partnership  engagements  with  U.S.  and  international  maritime  forces  to 
strengthen regional security. 
Information Sharing Initiatives: In an information dominated environment, initiatives that 
link  joint  warfighters,  the  technology  community,  and  academia  are  crucial  to  rapidly 
fielding  solutions  to  emerging  irregular  challenges.  These  initiatives  are  the  basis  for 
longer-term efforts to adapt and improve proficiency of Navy platforms to address irregular 
challenges. 
Doctrine: Development of Tri-Service (Navy, Marine Corps, and Coast Guard) Maritime 
Stability Operations doctrine that will enable a more effective response to instability in the 
littorals. 
Organization:  Navy  Expeditionary  Combat  Command,  which  continues  to  provide  in-
demand  capabilities  such  as  Maritime  Civil  Affairs  Teams,  Riverine  Forces,  Maritime 
Security  Forces,  Explosive  Ordnance  Disposal  Teams,  and  Expeditionary  Intelligence 
Teams. 
Today, the Navy continues to meet planned global operational commitments and respond 
to crises as they emerge. Overseas Contingency Operations continue with more than 12,000 
active and reserve Sailors serving around the globe and another 15,000 at sea in Central 
Command. Navy’s Carrier Strike Groups provide 30 percent of the close air support for 
troops on the ground in Afghanistan and our Navy and Marine Corps pilots fly almost 60% 
of  electronic  attack  missions.  Yet,  as  our  national  interests  extend  beyond  Iraq  and 
Afghanistan, so do the operations of our Navy. Over the last year, more than 50 percent of 
our Navy has been underway daily; globally present, and persistently engaged. Last year, 
our Navy conducted counter-piracy operations in the Indian Ocean and North Arabian Sea 
with a coalition of several nations, trained local forces in maritime security as part of our 
Global Maritime Partnership initiatives in Europe, South America, Africa and the Pacific 
and  forces  in  the  Sixth  Fleet  supported  NATO  in  complex  operations  in  Libya.  Navy 
responded with humanitarian assistance and disaster relief to the earthquake in Haiti, the 
flooding in Pakistan, and the earthquake and tsunami in Japan; and, conducted the world’s 
largest  maritime  exercise,  Rim  of  the  Pacific  (RIMPAC),  which  brought  together  14 
nations  and  more  than  20,000  military  personnel,  to  improve  coordination  and  trust  in 
multi-national operations in the Pacific. Our Sailors continue to deploy forward throughout 
the world, projecting US influence, responding to contingencies, and building international 
relationships that enable the safe, secure, and free flow of commerce that underpins our 
economic prosperity and advances the mission areas that address irregular challenges. 
The future vision of the Navy in meeting the uncertain challenges around the globe remains 
a  force  forward,  present,  and  persistent  in  areas  critical  to  the  national  interests  of  the 
Congressional Research Service

United States. CNO, in previous testimony,47 stated: Our Navy continues to conduct a high 
tempo  of  global  operations,  which  we  expect  to  continue  even  as  forces  draw  down  in 
Afghanistan. Global trends in economics, demographics, resources, and climate change 
portend  an  increased  demand  for  maritime  presence,  power,  and  influence.  America’s 
prosperity depends on the seas… and as disruption and disorder persist in our security 
environment,  maritime  activity  will  evolve  and  expand.  Seapower  allows  our  nation  to 
maintain U.S. presence and influence globally and, when necessary, project power without 
a costly, sizeable, or permanent footprint ashore. We will continue to maintain a forward-
deployed presence around the world to prevent conflict, increase interoperability with our 
allies,  enhance  the  maritime  security  and  capacity  of  our  traditional  and  emerging 
partners,  confront  irregular  challenges,  and  respond  to  crises.  To  continue  as  a  global 
force  in  the  preventive  and  responsive  mission  areas  that  confront  irregular  challenges, 
including those of irregular warfare, the Navy will be faced with increasing demand in a 
fiscally  induced  capacity  constrained  environment.  Constrained  capacity  requires  a 
prioritization of areas requiring persistent presence, to include those regions of current or 
forecast instability. Also required is an understanding of the risk incurred to mission, and 
to force, if we do not get that priority correct. We must ensure our Navy remains the finest, 
best  trained,  and  most  ready  in  the  world  to  sustain  key  mission  areas  that  support 
confronting irregular challenges, and has the ability to face a highly capable adversary. The 
Navy looks forward to working with Congress to address our future challenges and thank 
you for your support of the Navy’s mission and personnel at this critical crossroads in U.S. 
history.48

Appendix D. 2012 RAND Corporation Report 
Findings and Recommendations 
This appendix presents findings and recommendations from a 2012 report on maritime regular 
warfare by RAND Corporation, a research firm. 
Findings 
The report made the following findings, among others: 
The study’s main findings span the strategic, operational, and tactical levels. Several are 
specific to MIW, while others have implications both for MIW [maritime irregular warfare] 
and for IW operations more broadly. 
First, the maritime force is generally considered to play a supportive role to ground forces 
in IW and therefore has the potential to be underutilized even in IW operations conducted 
in a predominantly maritime environment.... 
Second, countries that have a prevalent maritime dimension associated with an insurgency 
could potentially benefit from the enhancement of civil-military operations (CMOs) in the 
maritime arena.... 
Third,  maritime  operations  in  IW  can  allow  the  United  States  to  scale  its  ground 
involvement in useful ways.... 
Fourth,  if  one  assumes  that  future  MIW  engagements  that  entail  building  a  partner’s 
capacity will resemble OEF-P [Operation Enduring Freedom—Philippines], it is important 
to  manage  strategic  expectations  based  on  realistic  assessments  of  the  partner’s 
capabilities.... 
Fifth, when building partner capacity, either in MIW or land-based IW, the United States 
should make efforts to provide equipment and technology that the partner will be able to 
maintain and operate without difficulty.... 
Sixth,  with  regard  to  operational  methods,  coastal  maritime  interdiction  can  play  an 
instrumental role in setting the conditions for success in IW by cutting the supply lines that 
sustain an insurgency.... 
Seventh, as the [1980s] Nicaragua case illustrates, U.S. partners in MIW may only have 
to influence and monitor the sensibilities of a local population, but the legitimacy of U.S. 
involvement may be tested in worldwide public opinion.... 
Finally, international cooperation in confronting MIW adversaries is often necessary, and 
the  U.S.  Navy  should  make  an  effort  to  ensure  that  it  is  tactically  and  operationally 
interoperable with partner navies in order to facilitate coordination....50 
Recommendations 
The report made the following recommendations, among others: 
The  findings  presented  here  have  several  direct  implications  for  the  U.S.  conventional 
Navy  and  Naval  Special  Warfare  Command  (NSW).  First,  U.S.  naval  forces  should 
continue to provide U.S. partners with suitable equipment that they will be able to operate 
and maintain and should continually strive to increase their interoperability with partner

forces. Second, U.S. naval forces may have to continue or expand training of partner forces 
to confront future MIW threats. Third, when conducting MIW, operating from a sea base 
offers advantages to NSW. However, due to the costs of such a practice, both NSW and 
the  conventional  Navy  must  also  recognize  that  decisions  regarding  when  and  where  to 
support sea basing of this sort need to be made carefully. Fourth, in support of future MIW 
operations,  NSW  is  likely  to  have  ongoing  requirements  for  maritime  interdiction  and 
containment.  Fifth,  the  United  States  could  benefit  from  maintaining  operational  and 
tactical  capabilities  with  which  to  assist  its  partners  in  surveillance,  particularly  against 
small submarines and mining threats. Sixth, NSW should consider increasing its capacity 
to conduct maritime-based CMOs. 
Conventional U.S. naval forces should similarly consider their role in supporting significant 
irregular ground operations launched from the sea, as well as their role in interdiction and 
containment campaigns. In contrast to those of NSW, conventional U.S. Navy capabilities to 
support IW might entail CMOs and related activities to a greater extent than direct action.51

Appendix E. Detention of Terrorist Suspects on U.S. 
Navy Ships 
This appendix presents additional background information on detention of terrorist suspects on 
U.S. Navy ships. 
On July 6, 2011, it was reported that 
The  U.S.  military  captured  a  Somali  terrorism  suspect  [named  Ahmed  Abdulkadir 
Warsame] in the Gulf of  Aden in  April and interrogated him  for  more than two  months 
aboard  a  U.S.  Navy  ship  before  flying  him  this  week  to  New  York,  where  he  has  been 
indicted on federal charges.... 
Other  U.S.  officials,  interviewed  separately,  said  Warsame  and  another  individual  were 
apprehended aboard a boat traveling from Yemen to Somalia by the U.S. military’s Joint 
Operations  Command.  The  vessel  was  targeted  because  the  United  States  had  acquired 
intelligence that potentially significant operatives were on board, the officials said. Court 
documents said the capture took place April 19. 
One of the senior administration officials who briefed reporters said that the other suspect 
was released “after a very short period of time” after the military “determined that Warsame 
was an individual that we were very much interested in for further interrogation.” 
According to court documents, Warsame  was interrogated on “all but a  daily basis”  by 
military and civilian intelligence interrogators. During that time, officials in Washington 
held a number of meetings to discuss the intelligence being gleaned, Warsame’s status and 
what to do with him. 
The options, one official said, were to release him, transfer him to a third country, keep 
him  prisoner  aboard  the  ship,  subject  him  to  trial  by  a  military  commission  or  allow  a 
federal court to try him. The decision to seek a federal indictment, this official said, was 
unanimous. 
Administration officials have argued that military commission jurisdiction is too narrow 
for some terrorism cases - particularly for a charge of material support for terrorist groups 
- and the Warsame case appeared to provide an opportunity to try to prove the point. 
But some human rights and international law experts criticized what they saw as at least a 
partial return to the discredited “black site” prisons the CIA maintained during the Bush 
administration.... 
Warsame was questioned aboard the ship because interrogators “believed that moving him 
to another facility would interrupt the process and risk ending the intelligence flow,” one 
senior administration official said. 
The  official  said  Warsame  “at  all  times  was  treated  in  a  manner  consistent  with  all 
Department  of  Defense  policies”  -  following  the  Army  Field  Manual  -  and  the  Geneva 
Conventions. 
Warsame  was  not  provided  access  to  an  attorney  during  the  initial  two  months  of 
questioning,  officials  said.  But  “thereafter,  there  was  a  substantial  break  from  any 
questioning of  the defendant  of four days,” court documents said.  “After this break, the 
defendant was advised of his Miranda rights” - including his right to legal representation – 
“and, after waiving those rights, spoke to law enforcement agents.” 
The four-day break and separate questioning were designed to avoid tainting the court case 
with information gleaned through un-Mirandized intelligence interrogation, an overlap that 
has posed a problem in previous cases. The questioning continued for seven days, “and the 
defendant waived his Miranda rights at the start of each day,” the documents said....

U.S. Navy Vice Adm. William H. McRaven alluded to the captures in testimony before a 
Senate  committee  last  week  in  which  he  lamented  the  lack  of  clear  plans  and  legal 
approvals for the handling of terrorism suspects seized beyond the war zones of Iraq and 
Afghanistan. 
At one point in the hearing, Sen. Carl Levin (D-Mich.), the chairman of the Senate Armed 
Services Committee, referred to “the question of the detention of people” and noted that 
McRaven had “made reference to a couple, I think, that are on a ship.” 
McRaven replied affirmatively, saying, “It depends on the individual case, and I'd be more 
than happy to discuss the cases that we've dealt with.”52 
Another press report on July 6, 2011, stated the following: 
In a telephone briefing  with reporters, senior administration officials  said Mr. Warsame 
and another person were captured by American forces somewhere “in the Gulf region” on 
April 19. Another official separately said the two were picked up on a fishing trawler in 
international waters between Yemen and Somalia. That other person was released. 
Mr. Warsame was taken to a naval vessel, where he was questioned for the next two months 
by  military  interrogators,  the  officials  said.  They  said  his  detention  was  justified  by  the 
laws of war, but declined to say whether their theory was that the Shabab are covered by 
Congress’s authorization to use military force against the perpetrators of the Sept. 11, 2001, 
attacks;  whether  the  detention  was  justified  by  his  interactions  with  Al  Qaeda’s  Yemen 
branch; or something else. 
The officials also said interrogators used only techniques in the Army Field Manual, which 
complies  with  the  Geneva  Conventions.  But  they  did  not  deliver  a  Miranda  warning 
because they were seeking to gather intelligence, not court evidence. One official called 
those  sessions  “very,  very  productive,”  but  declined  to  say  whether  his  information 
contributed to a drone attack in Somalia last month. 
After about two months, Mr. Warsame was given a break for several days. Then a separate 
group of law enforcement interrogators came in. They delivered a Miranda warning, but 
he waived his rights to remain silent and have a lawyer present and continued to cooperate, 
the  officials  said,  meaning  that  his  subsequent  statements  would  likely  be  admissible  in 
court. 
Throughout that period, administration officials were engaged in deliberations about what 
to do with Mr. Warsame’s case. Eventually, they “unanimously” decided to prosecute him 
in  civilian  court.  If  he  is  convicted  of  all  the  charges  against  him,  he  would  face  life  in 
prison. 
Last  week,  Vice  Adm.  William  H.  McRaven,  who  was  until  recently  in  charge  of  the 
military’s  Joint  Special  Operations  Command,  told  a  Senate  hearing  that  detainees  are 
sometimes kept on Navy ships until the Justice Department can build a case against them, 
or they are transferred to other countries for detention. 
Another senior administration official said Tuesday that such detentions are extremely rare, 
and that no other detainees are now being held on a Navy ship.53 
A July 7, 2011, press report stated the following:

In interrogating a Somali man for months aboard a Navy ship before taking him to New 
York this week for a civilian trial on terrorism charges, the Obama administration is trying 
out a new approach for dealing with foreign terrorism suspects. 
The administration,  which  was seeking to avoid sending a new prisoner to Guantánamo 
Bay, Cuba, drew praise and criticism on Wednesday [July 6] for its decisions involving the 
Somali  suspect,  Ahmed  Abdulkadir  Warsame,  accused  of  aiding  Al  Qaeda’s  branch  in 
Yemen and the Shabab, the Somali militant group.54 
A July 6, 2011, entry in a blog that reports on naval-related events stated that the U.S. Navy ship 
to which Warsame was taken was the amphibious assault ship Boxer (LHD-4).55 
An October 24, 2012, press report stated the following: 
Over  the  past  two  years,  the  Obama  administration  has  been  secretly  developing  a  new 
blueprint  for  pursuing  terrorists,  a  next-generation  targeting  list  called  the  “disposition 
matrix.” 
The matrix contains the names of terrorism suspects arrayed against an accounting of the 
resources  being  marshaled  to  track  them  down,  including  sealed  indictments  and 
clandestine operations. U.S. officials said the database is designed to go beyond existing 
kill lists, mapping plans for the “disposition” of suspects beyond the reach of American 
drones. 
Although the matrix is a work in progress, the effort to create it reflects a reality setting in 
among  the  nation’s  counterterrorism  ranks:  The  United  States’  conventional  wars  are 
winding down, but the government expects to continue adding names to kill or capture lists 
for years.... 
The database is meant to map out contingencies, creating an operational menu that spells 
out each agency’s role in case a suspect surfaces in an unexpected spot. “If he’s in Saudi 
Arabia,  pick  up  with  the  Saudis,”  the  former  official  said.  “If  traveling  overseas  to  al-
Shabaab [in Somalia] we can pick him up by ship. If in Yemen, kill or have the Yemenis 
pick him up.” 
Officials  declined  to  disclose  the  identities  of  suspects  on  the  matrix.  They  pointed, 
however,  to  the  capture  last  year  of  alleged  al-Qaeda  operative  Ahmed  Abdulkadir 
Warsame off the coast of Yemen. Warsame was held for two months aboard a U.S. ship 
before being transferred to the custody of the Justice Department and charged in federal 
court in New York. 
“Warsame  was  a  classic  case  of  ‘What  are  we  going  to  do  with  him?’”  the  former 
counterterrorism  official  said.  In  such  cases,  the  matrix  lays  out  plans,  including  which 
U.S.  naval  vessels  are  in  the  vicinity  and  which  charges  the  Justice  Department  should 
prepare.56 
An October 6, 2013, press report stated the following: 
An accused operative for Al Qaeda seized by United States commandos in Libya over the 
weekend  is  being  interrogated  while  in  military  custody  on  a  Navy  ship  in  the

Mediterranean Sea, officials said on Sunday [October 6]. He is expected eventually to be 
sent to New York for criminal prosecution. 
The  fugitive,  known  as  Abu  Anas  al-Libi,  is  seen  as  a  potential  intelligence  gold  mine, 
possessing perhaps two decades of information about Al Qaeda, from its early days under 
Osama bin Laden in Sudan to its more scattered elements today.  
The decision to hold Abu Anas and question him for intelligence purposes without a lawyer 
present follows a pattern used successfully by the Obama administration with other terrorist 
suspects, most prominently in the case of Ahmed Abdulkadir Warsame, a former military 
commander with the Somali terrorist group Shabab.... 
“Warsame is the model for this guy,” one American security official said.... 
Abu Anas is being held aboard the U.S.S. San Antonio, a vessel brought in specifically for 
this mission, officials said.57 
A June 27, 2014, press report stated the following: 
Right now, a suspected terrorist is sitting in the bowels of a U.S. Navy warship somewhere 
between the Mediterranean Sea and Washington, D.C. Ahmed Abu Khattala, the alleged 
leader of the September 2012 attack on the U.S. embassy in Benghazi, Libya, is imprisoned 
aboard  the  USS  New  York,  likely  in  a  bare  cell  normally  reserved  for  U.S.  military 
personnel facing disciplinary action at sea. En route to the United States for more than a 
week, he’s being questioned by military and civilian interrogators looking for critical bits 
of intelligence before he’s read his Miranda rights, formally arrested, and transferred to the 
U.S. District Court in Washington, where he’ll face trial. Meanwhile, the sailors aboard are 
going  about  the  daily  business  of  operating  an  amphibious  transport  ship—even  as  the 
ship’s mission has been redefined by the new passenger in their midst. 
This isn’t the first time the Navy has played such a critical, curious, and largely under-
reported  role  in  U.S.  counterterrorism  efforts.  In  2011,  Ahmed  Abdulkadir  Warsame,  a 
military  commander  for  the  Somali  terrorist  group  al-Shabab,  was  captured  aboard  a 
fishing boat in the Gulf of Aden and detained by the Navy, on the high seas, for two months. 
In  2013,  Abu  Anas  al-Libi,  the  alleged  mastermind  of  the  1998  terrorist  attacks  on 
American embassies in Kenya and Tanzania, was held aboard the USS San Antonio—an 
identical ship to the one being used this week. Both men were interrogated at sea before 
being flown to the United States to face criminal charges in federal courts.... 
In many ways, it’s not surprising that the U.S. government has been turning Navy assets 
into floating prisons for these dangerous men. Taking the slow route back to the United 
States offers interrogators the time and space to gather crucial intelligence from high-value 
sources like al-Qaeda-linked operatives. During the two months that Warsame was at sea, 
a  select  team  of  FBI,  CIA,  and  Defense  Department  officials,  part  of  the  Obama 
administration’s High-Value Detainee Interrogation Group, questioned the Somali terrorist 
on “all but a daily basis.” He was cooperative throughout and some reports suggest that 
subsequent U.S. counterterrorism operations, including a drone attack in Somalia shortly 
after  his  capture,  were  a  direct  result  of  intelligence  Warsame  provided  to  authorities. 
While  al-Libi  was  only  detained  at  sea  for  about  a  week—a  chronic  medical  condition 
prevented  him  from  being  held  on  a  ship  for  an  extended  period—reports  suggest  that 
similar intelligence-collection efforts were underway in his case as well. 
The U.S. government has also embraced the approach because it has limited options for 
holding and interrogating men like Abu Khattala after capture. The Obama administration 
remains committed to ending detention operations at Guantánamo Bay, Cuba. While the

facility is still home to almost 150 alleged terrorists, the United States has not sent any new 
detainees there since March 2008. Detaining suspected terrorists at other overseas facilities 
is likewise not an option. For a time, U.S.-run prisons in Afghanistan were a possibility. 
But the detention facility in Parwan is now an Afghan-run prison, and using facilities in 
other countries would raise a host of legal, operational, and humanitarian concerns. Even 
if U.S. officials were willing to forgo the opportunity to question Abu Khattala before he’s 
arraigned in federal court and provided with a lawyer, flying alleged terrorists to the United 
States  immediately  presents  its  own  set  of  problems.  Seemingly  small  operational  and 
political  considerations  about  the  ways  in  which  the  United  States  transports  terrorists 
captured abroad have major strategic implications, particularly given lingering questions 
about U.S. rendition efforts under the Bush administration. In this context, the Navy has 
taken on the role of high-seas prison warden, even as lawyers continue to debate whether 
and  what  international  legal  rules  apply  to  terrorists  captured  abroad  and  detained, 
temporarily, on a ship.58

Press Reports 
A November 30, 2016, press report states the following: 
USSOCOM is currently pursuing two programmes to enhance the sub-surface capabilities 
of US Navy (USN) SEALs including the Shallow Water Combat Submersible (SWCS) and 
Dry Combat Submersible (DCS). Both solutions are fully enclosed vehicles for operators, 
thereby reducing any requirement for teams to wear rebreathing equipment during mission 
insertions and extractions.... 
The main difference between SWCS and DCS is range, with the latter solution providing 
a longer insertion distance with a greater depth capability. 
The SWCS, for example, is being designed to replace legacy Mk 8 Mod 1 SEAL Swimmer 
Delivery Vehicles (SDVs), bringing an improved electronic architecture and software on 
top of the requirements list for NSWC. SOF sources associated with USSOCOM explained 
to IHS Jane‘s how the first SWCS could be delivered to the Command in 2017. This would 
be followed by extensive operational evaluation with NSWC elements ahead of initial and 
full entry into service, sources added. 
According to USSOCOM officials, a total of two SWCS platforms will be procured by the 
DoD in 2017, along with associated batteries, trailers, mission system suites, and spares. 
Capable of transporting six operators at low-level depths close to the surface, the SWCS 
can  carry  a  total  payload  of  10,000  lb  (4,535  kg).  SWCS  contractor  Teledyne  Brown 
Engineering  was  unable  to  provide  further  details  to  IHS  Jane’s  because  of  operational 
security  reasons.  However,  industry  sources  have  suggested  that  the  SWCS  measures 
approximately 22 ft (6.7 m) in length and 5 ft in width. 
The SWCS has yet to be officially designated, but the nomenclature Mk 9 is expected to 
be  granted  to  the  platform  type.  Teledyne  Brown  Engineering  beat  the  incumbent 
manufacturer of the Mk 8 Mod 1, Columbus Group, to the programme in 2011 when it was 
awarded a USD383 million contract by the DoD. 
Ahead of SWCS’s entry into service, General Dynamics Information Technology (GDIT) 
continues to assist the NSWC with ongoing support for legacy Mk 8 Mod 1 SDV systems. 
Work  will  include  projects  relating  to  SDVs  as  well  as  other  NSWC-specific  efforts 
associated with the Maritime Mission Systems Division. The latest support contract, worth 
USD4 million, was signed in December 2015. 
Elsewhere, the DCS solution has been designed as a dry diver lock-in/lock-out solution, 
capable  of  inserting  and  extracting  personnel  and  all  associated  combat  equipment, 
including  in  hostile  waters,  according  to  USSOCOM  sources.  The  development  of  this 
option follows the cancellation of the Advanced SEAL Delivery System (ASDS) in 2006. 
Designed to carry six operators, the DCS has a larger payload capacity than the SWCS, 
with the ability to carry up to 40,000 lb at depths as low as 58 m. Sources also informed 
IHS Jane’s that the DCS could have a maximum operating range of 60 n miles.

In  July  2016,  it  was  announced  that  Lockheed  Martin  and  Submergence  Group  would 
jointly design, develop, and manufacture the DCS for USSOCOM, with industry figures 
reiterating the vessel’s ability to provide improved endurance and operating depths. 
According  to  Lockheed  Martin,  a  USD166  million  contract  will  involve  the  delivery  of 
three DCS  vehicles over a five-year period, with the gross weight for each vessel being 
more than 30 tons. A company spokesperson explained to IHS Jane’s how NSWC concepts 
of  operations  would  see  the  DCS  launched  at  a  stand-off  position  from  surface  vessels, 
before  inserting  SEAL  operators  over  “long  distances  underwater”  onto  objectives  and 
target areas.... 
Details regarding the DCS design remain scarce. However, sources indicated to IHS Jane’s 
that  the  solution  will  feature  technology  drawn  from  Lockheed  Martin’s  S302  Manned 
Combat Submersible (MCS) craft, which is capable of carrying six personnel as well as a 
pilot and navigator. 
According to Lockheed Martin company literature, “The dry one-atmosphere environment 
of these vehicles provides an alternative to traditional wet submersibles being used by the 
US and international Special Forces communities today, and will deliver operators to their 
destination in better physical condition to complete a mission.” 
Vessels are fitted with standard inertial navigation systems and Doppler velocity logs, as 
well  as  a  communications  suite  featuring  an  underwater  telephone  and  a  UHF  radio; 
obstacle  avoidance  sonar;  and  fathometer.  Additional  sensor  payloads,  dependent  upon 
mission requirements, can also be integrated, Lockeed Martin explained. 
The S302 MCS measures 31 ft in length, and can operate 100 m below the surface for more 
than 24 hours. The craft can travel up to 60 n miles at a 5 kt cruising speed, although it has 
a top speed of more than 7.5 kt for rapid reaction. 
USSOCOM continues to integrate Dry Deck Shelter (DDS) technology on board a variety 
of  Ohio-class  nuclear-powered  ballistic  missile  submarines  (SSBNs)  and  Virginia-class 
nuclear-powered attack submarines (SSNs) for special operations support.... 
Although a total of six DDS systems are currently in service with the USN and USSOCOM, 
by the end of 2016 nine submarines will possess DDS capabilities, enabling them to launch 
and recover SDVs, sources explained. 
Featuring automated launch-and-recovery technology, DDS enables combat divers to enter 
and leave the dry dock individually, as was explained during a press briefing by NSWC 
officials at the Special Operations Forces Industry Conference (SOFIC) in Tampa, Florida, 
in May 2016. 
In 2017, the USN aims to concentrate on a series of modifications to the DDS in order to 
allow for the integration of DCS and SWCS, including the relocation of equipment stowage 
in the DDS and upgrades in lighting, cameras, and mechanical noise reduction. 
Industry sources have noted that DDS solutions are being extended by 50 inches to enable 
the integration of DCS and SWSC variants, thereby supporting a ‘mothership’ concept of 
operations (CONOPS) for maritime special forces. This would enable SOF teams to insert 
at  greater  distances  from  submarines  and  surface  vessels,  before  entering  the  water  at  a 
suitable stand-off range from target areas and inserting via onboard DCS or SWCS craft.62 
A September 15, 2016, press report states the following: 
SEALs will soon have new underwater vehicles delivering them to targets that officials say 
will make a huge difference during missions.

Review, November 30, 2016.

SEALs now use a delivery vehicle that one SEAL described as a kind of underwater sled.  
SEALs ride in the sled in full scuba gear completely exposed to the water, in often freezing 
cold and in “pure blackout” conditions and total silence for eight to 10 hours. 
Ask a SEAL what that’s like, and they'll say it’s like being locked in a cold, dark, wet closet 
for hours.... 
The  new  vehicles,  which  are  called  dry  combat  submersibles,  will  be  akin  to  mini-
submarines, and allow SEALs to stay  warmer and drier for longer, and more physically 
ready, as they close in on their target.  
That’s a huge advantage for missions that one retired SEAL who is now a congressman 
described as “can't fail.”... 
The vehicles will also allow the SEALs to communicate before a mission, compared with 
“only seeing your buddy’s eyes” and a glow stick for 10 hours, the SEAL joked.  
The first submersible is due to arrive in July 2018, and it will be operational as early as the 
fall. Final testing is to be completed in 2019.  
As SEALs await the delivery of the first vehicle, they have two “demonstrator” vehicles to 
experiment with.... 
That demonstrator is about 39 feet long, is about 7 to 8 feet in diameter, and weighs about 
30 tons. So far, it has gone up to five knots for 60 nautical miles.... 
It is also surface-launched, which means it is launched into the water by a crane or from a 
surface ships with a crane, versus from a submarine.  
The  vehicle  is  able  to  hold  up  to  eight  SEALs  and  their  gear,  in  addition  to  a  pilot  and 
navigator.  
The  submersible  consists  of  three  compartments:  a  swimmers’  compartment  where  the 
SEALs will ride for the duration of the time, a “line in and line out” compartment where 
they exit and enter the submersible, and a compartment for the navigator and pilot.  
The  swimmers’  compartment  is  only  about  10  to  12  feet  long,  which  could  be  a  tight 
squeeze for eight SEALs.  
Still, officials say it’ll be a huge improvement over the current systems. 
“The DCS Program is on track to provide a capability that our warfighters have not had in 
a long time,” said Navy Capt. Kate Dolloff, who is in charge of all maritime programs for 
Special Operations Command Acquisition, Technology and Logistics.  
“We still have a long way to go, but a stepped approach using technology demonstrators 
to  mitigate  risk  and  a  close  relationship  with  the  user  community  has  been  extremely 
successful to date and led to contract award,” she said.  
The  U.S.  Special  Operations  Command  (SOCOM)  finalized  a  contract  in  July  with 
Lockheed Martin for the first submersible to be delivered in July 2018, with the option of 
two more by 2020—an unusually fast schedule for acquiring new technology.  
The total cost for the three submersibles is $236 million.  
The timeline and cost is  years shorter and hundreds of  millions cheaper than a previous 
submersible program, which was killed in 2006 after cost overruns and other issues.  
That program would have cost $1 billion for one submersible and have taken two to three 
times longer to build, officials said.  
Officials  say  the  costs  are  much  lower  because  they're  taking  off-the-shelf  commercial 
technology developed by Lockheed Martin and modifying it to fit their needs, whereas the 
previous program started from scratch.  
Congressional Research Service

Officials say the new vehicles will have 80 to 90 percent of the same capability, but will 
be delivered much faster at a much lower cost.  
The new program also comes with a “fixed price incentive fee” structure, where the cost 
of the program is fixed and any overruns are shared with the manufacturer.63 
A July 22, 2016, press report states that 
... a new ‘missile sub’ promises to deliver to battle underwater far more easily—and keep 
them dry when they travel.  
Called  the  Swimmer  Delivery  Vehicle,  it  will  be  built  by  Lockheed  Martin  and 
Submergence  Group  after  winning  a  US$166  million  contract  to  supply  the  US  Special 
Operations Command (USSOCOM) with a new class of combat submersibles. 
According  to  Lockheed,  the  three  30-ton  (27-tonne)  DCS  [Dry  Combat  Submersible] 
vehicles  that  it  is  contracted  to  build  will  allow  warfighters  to  travel  deeper  and  farther 
underwater than today. 
The craft are dry submersibles that support two operators (pilot and navigator) plus up to 
six swimmers with the ability to lock them out and in.  
‘The  dry  one-atmosphere  environment  of  these  vehicles  provides  an  alternative  to 
traditional  wet  submersibles  being  used  by  the  U.S.  and  international  Special  Forces 
communities  today,  and  will  deliver  operators  to  their  destination  in  better  physical 
condition to complete a mission,’ Lockheed Martin says.... 
It will carry two pilots and six passengers, have a depth rating of 328 ft (100 m), a lock-
out depth of 98 ft (30 m), and a top speed of 5 knots (6 mph, 9 km/h). 
Lockheed says the new DCS will boast improved hydrodynamics and propulsion compared 
to the previous vehicles.64 
An August 20, 2014, blog post states the following: 
The  U.S.  Navy  is  hard  at  work  developing  new  underwater  transports  for  its  elite 
commandos.  The  SEALs  expect  the  new  craft—and  improvements  to  large  submarine 
“motherships” that will carry them—to be ready by the end of the decade. 
SEALs have ridden in small submersibles to sneak into hostile territory for decades. For 
instance, the special operators reportedly used the vehicles to slip into Somalia and spy on 
terrorists in 2003. 
Now the sailing branch is looking to buy two new kinds of mini-subs. While details are 
understandably  scarce,  the  main  difference  between  the  two  concepts  appears  to  be  the 
maximum range. 
The Shallow Water Combat Submersible will haul six or more naval commandos across 
relatively short distances near the surface. The SWCS, which weighs approximately 10,000 
pounds, will replace older Mark 8 Seal Delivery Vehicles, or SDVs. 
The other sub, called the Dry Combat Submersible, will carry six individuals much farther 
and at greater depths. The most recent DCS prototype weighs almost 40,000 pounds and 
can travel up to 60 nautical miles while 190 feet below the waves. 
Commandos could get further into enemy territory or start out a safer distance away with 
this new vehicle. SEALs could also use this added range to escape any potential pursuers.

Both new miniature craft will also be fully enclosed. The current SDVs are open to water 
and the passengers must wear full scuba gear—seen in the picture above. 
In addition, the DCS appears to pick up where a previous craft, called the Advanced SEAL 
Delivery System, left off. The Pentagon canceled that project in 2006 because of significant 
cost overruns. 
But the Navy continued experimenting with the sole ASDS prototype for two more years. 
The whole effort finally came to a halt when the mini-sub was destroyed in an accidental 
fire. 
Special Operations Command hopes to have the SWCS ready to go by 2017. SOCOM’s 
plan is to get the DCS in service by the end of the following year. 
Underwater motherships 
SOCOM and the sailing branch also want bigger submarines to carry these new mini-subs 
closer  to  their  targets.  For  decades  now,  attack  and  missile  submarines  have  worked  as 
motherships for the SEALs. 
Eight  Ohio-  and  Virginia-class  subs  currently  are  set  up  to  carry  the  special  Dry-Deck 
Shelter used to launch SDVs, according to a presentation at the Special Operations Forces 
Industry Conference in May. 
The DDS units protect the specialized mini-subs inside an enclosed space. Individual divers 
also can come and go from the DDS airlocks. 
The  first-in-class  USS  Ohio—and  her  sisters  Michigan,  Florida  and  Georgia—carried 
ballistic missiles with nuclear warheads during the Cold War. The Navy had expected to 
retire the decades-old ships, but instead spent billions of dollars modifying them for new 
roles. Today they carry Tomahawk cruise missiles and SEALs. 
The Virginias—Hawaii, Mississippi, New Hampshire, North Carolina and the future North 
Dakota—are  newer.  The  Navy  designed  these  attack  submarines  from  the  keel  up  to 
perform a variety of missions. 
SOCOM  projects  that  nine  submersible  motherships—including  North  Carolina  as  a 
backup—will be available by the end of the year. 
The Navy has a pool of six shelters to share between the subs. SOCOM expects the DDS 
to still be in service in 2050. 
But  prototype  DCS  mini-subs  cannot  fit  inside  the  current  shelter  design.  As  a  result,  a 
modernization program will stretch the DDS units by 50 inches, according to SOCOM’s 
briefing. 
The project will also try to make it easier to launch undersea vehicles and get them back 
into the confines of the metal enclosure. Right now, divers must manually open and close 
the outside hatch to get the SDVs out. 
Crews then have to drive the craft back into the shelter without any extra help at the end of 
a  mission—underwater  and  likely  in  near-total  darkness.  The  sailing  branch  wants  to 
automate this process. 
With any luck, the SEALs will have their new undersea chariots and the motherships to 
carry them ready before 2020.65
