Navy Role in Irregular Warfare and Counterterrorism 
 
Summary 
The Department of Defense (DOD) is placing an increased planning and budgeting emphasis on 
irregular warfare (IW) operations, such as counterinsurgency operations. In addition, 
counterterrorism (CT) operations have been a DOD area of emphasis since the terrorist attacks of 
September 11, 2001. The Navy for several years has carried out a variety of IW and CT activities, 
and has taken some steps in recent years to strengthen its ability to conduct such activities. The 
Navy’s IW and CT activities pose a number of potential oversight issues for Congress, including 
the definition of Navy IW activities, specific Navy IW budget priorities, and how much emphasis 
to place on IW and CT activities in future Navy budgets.

Navy Role in Irregular Warfare and Counterterrorism 
 
Introduction 
The Department of Defense (DOD) is placing an increased planning and budgeting emphasis on 
irregular warfare (IW) operations, such as counterinsurgency operations. In addition, 
counterterrorism (CT) operations have been a DOD area of emphasis since the terrorist attacks of 
September 11, 2001. The Navy for several years has carried out a variety of IW and CT activities, 
and has taken some steps in recent years to strengthen its ability to conduct such activities. The 
Navy’s IW and CT activities pose a number of potential oversight issues for Congress, including 
the definition of Navy IW activities, specific Navy IW budget priorities, and how much emphasis 
to place on IW and CT activities in future Navy budgets. 
Background 
Navy Irregular Warfare (IW) Operations1 
Operations in Iraq and Afghanistan 
Among the most readily visible of the Navy’s current IW operations are those being carried out 
by Navy sailors serving ashore in Iraq and Afghanistan. The Department of the Navy, which 
includes the Navy and Marine Corps, stated in early 2010 that: 
The Navy has 53,000 active and reserve sailors continually deployed in support of the 
contingency operations overseas serving as members of carrier strike groups, expeditionary 
strike groups, Special Operating Forces, Seabee units, Marine forces, medical units, and as 
IAs [individual augmentees]. Our Sailors are fully engaged on the ground, in the air, and at 
sea in support of operations in Iraq and Afghanistan. On the ground, our Navy has 12,300 
active and reserve Sailors in Central Command supporting Navy, Joint Force and Combatant 
Commander requirements. Navy Commanders are leading six of the twelve U.S.-lead 
Provincial Reconstruction Teams in Afghanistan. A significant portion of the combat air 
missions over Afghanistan are flown by naval air forces. Our elite teams of Navy SEALs 
[i.e., Sea-Air-Land special operations forces] are heavily engaged in combat operations, 
Navy Explosive Ordnance Disposal platoons are defusing Improvised Explosive Devices and 
landmines. Our SEABEE construction battalions are rebuilding schools and restoring critical 
infrastructure. Navy sealift is delivering the majority of heavy war equipment to 
CENTCOM, while Navy logisticians are ensuring materiel arrives on time. Our Navy 
doctors are providing medical assistance in the field and at forward operating bases. Navy 
IAs are providing combat support and combat service support for Army and Marine Corps 
personnel in Iraq and 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. On the water, Navy Expeditionary Combat Command Riverine forces are working 
closely with the Iraqi Navy to safeguard Iraqi infrastructure and provide maritime security in 
key waterways. Navy forces are also intercepting smugglers and insurgents and protecting 
Iraqi and partner nation oil and gas infrastructure. We know the sea lanes must remain open 
                                                             
1 Unless otherwise indicated, information in this section is taken from a Navy briefing to CRS on July 31, 2009, on 
Navy IW activities and capabilities.

Navy Role in Irregular Warfare and Counterterrorism 
 
for the transit of oil, the lifeblood of the Iraqi economy, and our ships and sailor are making 
that happen.2 
The Department of the Navy also stated: 
On any given day there are approximately 12,300 Sailors ashore and another 9,800 afloat 
throughout the U.S. Central Command region conducting riverine operations, maritime 
infrastructure protection, explosive ordnance disposal, combat construction engineering, 
cargo handling, combat logistics, maritime security, and other forward presence activities. In 
collaboration with the U.S. Coast Guard, the Navy also conducts critical port operations, port 
and oil platform security, and maritime interception operations. Included in our globally 
sourced forces are 15,600 IAs serving in a variety of joint or coalition billets, either in the 
training pipeline or on station. As these operations unfold, the size and type of naval forces 
committed to them will likely evolve, thereby producing changes to the overall force posture 
of naval forces. Long after the significant land component presence is reduced, naval forces 
will remain forward.... 
Strike operations are conducted to damage or destroy objectives or selected enemy 
capabilities. Recent examples include simultaneous close air support missions that are 
integrated and synchronized with coalition ground forces to protect key infrastructure, deter 
and disrupt extremist operations or hostile activities, and provide oversight for reconstruction 
efforts in support of Operations Enduring Freedom and Iraqi Freedom.... 
We are refocusing this strategic capability more intensely in Afghanistan in an effort to 
counter the increasing threat of a well-armed anti-Coalition militia including Taliban, al 
Qaeda, criminal gangs, narcoterrorists, and any other antigovernment elements that threaten 
the peace and stability of Afghanistan. Our increased efforts to deter or defeat aggression and 
improve overall security and counter violent extremism and terrorist networks advance the 
interests of the U.S. and the security of the region. The FY 2010/FY 2011 contingency 
operations requests support the expansion of capabilities sufficient to secure Afghanistan and 
prevent it from again becoming a haven for international terrorism and associated militant 
extremist movements. 3 
More specifically, the Navy states that operations performed by Navy personnel in Iraq and 
Afghanistan include the following: 
•  close air support (CAS) and airborne reconnaissance operations, in which 
Navy aircraft account for 30% of all such missions; 
•  expeditionary electronic warfare operations, including operations to defeat 
improvised explosive devices (IEDs), 75% of airborne electronic attack 
operations in Iraq, 100% of such operations in Afghanistan, and operations to 
counter insurgent and extremist network communications; 
•  intelligence and signals intelligence operations, including operations to identify, 
map, and track extremist activity, and operations involving tactical intelligence 
support teams that are deployed with special operations forces (SOF);

Navy Role in Irregular Warfare and Counterterrorism 
 
•  explosive ordnance disposal (EOD) operations, including defusing IEDs, 
clearing land mines, destroying captured weapon and explosive caches, and 
investigating blast scenes so as to obtain evidence for later prosecution. 
•  riverine warfare operations to secure waterways such as the Tigris and 
Euphrates rivers and the Haditha dam; 
•  maritime security operations, including operations to intercept smugglers and 
extremists going to Iraq and Kuwait, and operations to guard Iraqi and U.S. 
infrastructure, facilities, and supply lines, such as ports and oil and gas platforms 
and pipelines; 
•  medical and dental services in Iraq and Afghanistan provided by a total of more 
than 1,800 naval medical personnel; 
•  logistics operations, including transporting of 90% of military equipment for Iraq 
and Afghanistan on military sealift ships, operating ports in Iraq and Kuwait, and 
providing contracting services and reconstruction using Iraqi firms; 
•  engineering and construction operations, such as rebuilding schools, repairing 
roads, reconstructing electrical, water and sewer systems, and training and 
equipping Iraqi engineers; 
•  provincial reconstruction operations in Iraq and Afghanistan; and 
•  legal operations, including prosecution of special-group criminals and assisting 
Iraqis in drafting governing documents. 
Other Operations 
In addition to participating in U.S. military operations in Iraq and Afghanistan, the Navy states 
that its IW operations also include the following: 
•  security force assistance operations, in which forward-deployed Navy ships 
exercise and work 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 provide 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, which have increased since 2008.4 
The Navy states that enduring areas of focus for the Navy’s role in IW include the following: 
•  enhancing regional awareness, which enables better planning, decision making, 
and operational agility;

Navy Role in Irregular Warfare and Counterterrorism 
 
•  building maritime partner capability and capacity, so as to deny sanctuaries 
to violent extremists; and 
•  outcome-based application of force, so as to maintain continuous pressure on 
extremist groups and their supporting infrastructure. 
Individual Augmentees (IAs) 
Many of the Navy’s contributions to irregular warfare operations around the world are made by 
Navy individual augmentees (IAs)—individual Navy sailors assigned to various DOD operations. 
The Department of the Navy stated in early 2009 that: 
The Navy provides approximately 15,600 sailors in the form of IA’s, including 3,800 
personnel in the training pipeline, to fulfill the OCO mission requirements of the Combatant 
Commanders (COCOM). Approximately 8,500 of these IA’s are funded in the baseline 
budget filling core missions such as maritime and port security, airlift support, and 
JTF/COCOM staff support. An additional 2,700 IA’s are funded in the baseline budget in 
support of adaptive core missions including Counter IED, Combat Support, Military Police, 
Base Operations, Intel and Medical. The overseas contingency request includes 4,400 over 
strength requirements for temporary Navy overseas IA missions such as civil affairs, 
provincial reconstruction, training teams, detainee operations and customs inspections. IAs 
are making a significant impact in more than 20 countries around the world. They are 
assigned individually, rather than as part of a traditional unit, to fill shortages or provide 
specialized knowledge or skill sets. IAs have been assigned in Afghanistan, Iraq, Kuwait, 
Djibouti, Liberia, Chad, Cuba, Bahrain, Qatar, Colombia, Philippines, United Arab Emirates, 
Sudan, Oman, Pakistan, Germany, Spain, Italy, Honduras, Panama, Peru, Trinidad and 
Tobago, and Haiti. These IA’s provide commanders with mission tailored, globally 
distributed forces. The Navy identifies both active and reserve service members with specific 
skill sets to fill IA roles, and the Marine Corps relies principally on activated reserve 
members to fill IA positions vacated by forward-deployed active component Marines.5 
IW Initiatives in Navy Budget 
Discussion in FY2011 Department of the Navy Budget Highlights Book 
The Department of the Navy’s FY2011 budget highlight books states: 
The FY 2011 [Department of the Navy] budget is the product of a holistic assessment of 
capabilities, requirements and risks and is consistent with the 2010 Quadrennial Defense 
Review (QDR). Enhancements in the area of Irregular Warfare (IW) are realized through 
increased support of Special Operations Forces and expanded capacity for littoral, brown 
water, and riverine missions.6 
It also states: 
The FY 2011 budget includes the establishment of a new RC [reserve component] riverine 
training squadron which will compliment the three existing AC [active component] riverine

squadrons. The fourth riverine squadron will increase the riverine capacity to conduct brown 
water training and partnership activities in order to meet COCOM demands.7 
It also states: 
In keeping with the priorities of the Secretary of Defense, the FY 2011 budget continues to 
rebalance our investment programs in order to institutionalize and enhance our capabilities to 
fight the wars of today and the most-likely scenarios in the future, while at the same time 
providing a hedge against other risks and contingencies. 
The FY 2011 budget concentrates investment in platforms and systems that maintain the 
advantage against future threats and across the full spectrum of operations. Procurement of 
the Littoral Combat Ship (LCS), Intelligence, Surveillance and Reconnaissance (ISR) 
Unmanned Aerial Vehicles (UAVs) and other programs that support irregular warfare and 
capacity building reflect that shift. However, even as the Department begins to shift 
resources and institutional weight towards supporting the current conflicts and other 
potential irregular campaigns, we still must contend with the security challenges posed by 
the military forces of other countries – from those actively hostile to those at strategic 
crossroads.8 
It also states: 
The Navy’s shipbuilding budget represents the best balance between high-end, hybrid and 
irregular warfare capabilities. It funds a continuum of forces ranging from the covert 
Virginia class submarine, the multi-mission DDG-51 destroyer, the multi-role Landing 
Helicopter Assault Replacement (LHA(R)), to the Littoral Combat Ship (LCS) and the Joint 
High Speed Vessel (JHSV) with their greater access to littoral areas. This balance continues 
to pace future threat capabilities while fully supporting current irregular warfare operations 
and supporting maritime security and stability operations in the littorals.9 
The book mentions the irregular warfare capabilities of the Navy’s new P-8 aircraft,10 states that 
Department of the Navy research and development initiatives support both traditional and 
irregular warfare demands in several aviation programs,11 and states more generally that 
asymmetric and irregular warfare constitute one of 13 focus areas for the science and technology 
(S&T) portion of the Department of the Navy’s research and development efforts.12 
The book states the following regarding the Overseas Contingency Operations (OCO) portion of 
the Department of the Navy’s proposed FY2011 budget: 
The current request includes incremental costs to sustain operations, manpower, equipment 
and infrastructure repair, as well as equipment replacement. These costs include aviation and 
ship operations, combat support, base support, USMC operations and field logistics, as well 
as IAs, activated reservists and other special pays. Navy is requesting funding for 4,400 IAs 
in the FY 2011 OCO request for service members filling non-traditional Navy missions such 
as provincial reconstruction teams, detainee operations, civil affairs, training teams, customs

inspections, counter IED, and combat support. Finally, both the FY 2010 and the FY 2011 
full year requests reflect the initial shift in forces from Iraq to Afghanistan. The Department 
of the Navy requests $3.9 billion in FY 2010 for supplemental requirements and $18.5 
billion for FY 2011 to support increased OPTEMPO for contingency operations. Since 2009, 
total funding trends reflect the Department’s efforts to reduce reliance on supplemental 
appropriations and include OCO costs with the budget request. Figure 6 reflects the current 
status of FY 2009, FY 2010, and FY 2011 funding for OCO. 
The FY 2011 OCO O&M request specifically provides the resources required to meet 
increased CENTCOM demand, to include a substantial increase in flight hours associated 
with the shift from OIF [Operational Iraqi Freedom—i.e., operations in Iraq] to OEF 
[Operation Enduring Freedom—i.e., operations in Afghanistan] and the increased Carrier 
Strike Group presence that ensures there are no Air Tasking Order gaps; the Navy’s FY 2010 
OCO appropriation did not fully capture OEF execution requirements. 
The supplemental request for FY 2010 and the full-year request for FY 2011 supports the 
deployment, operation and sustainment of two regimental combat teams, a division-level 
headquarters unit, Seabee battalions, aviation and ship operations, combat support, base 
support, transportation of personnel and equipment into theater, and associated enabling 
forces to Afghanistan. The additional funding will support expansion into new areas of 
operation and establishment of a new command within the southern region of Afghanistan. 
Increased funding is also needed for service contracts supporting unmanned aerial systems 
(UAS) providing intelligence, surveillance, and reconnaissance (ISR) and additional in-
theater maintenance. The amendment will also fund increased fuel costs in FY 2010.13 
Longer List of Navy IW Budget Initiatives 
The Navy states that a longer list of Navy budget initiatives for creating or expanding its IW 
capabilities includes the following, which are not necessarily listed in any particular order of 
priority: 
•  shifting funding for the Naval Expeditionary Combat Command (or NECC—see 
“Navy Expeditionary Combat Command (NECC)” below) from the wartime 
operations part of the Navy’s budget into the Navy’s “base” budget (aka, the 
“regular” part of the Navy’s budget); 
•  delivering expanded counter-IED and EOD capabilities; 
•  deploying riverine squadrons and maritime expeditionary support squadrons; 
•  training Navy personnel in foreign languages, regional affairs, and cultures; 
•  using the JFK Irregular Warfare Center at the Office of Navy Intelligence (ONI) 
to provide intelligence support to joint IW/SOF operations; 
•  ship operation and acquisition, including: 
•  using ships (such as amphibious ships) as partnership stations, such as the 
Southern Partnership Station (SPS) and the Africa Partnership Station (APS) 
(see “Partnership Stations” below);

that is to be flown form Navy aircraft carriers); 
•  a sea-based, medium-range unmanned aerial vehicle (UAV); 
•  the small tactical unmanned aerial system (STUAS); 
•  expanding the Navy’s sea-based ballistic missile defense (BMD) capabilities;17 
and 
•  expanding the Navy’s cyberwarfare operations force. 
A separate list of Navy budgetary areas of emphasis for IW includes the following: 
•  ships and aircraft; 
•  persistent intelligence, surveillance, and reconnaissance (ISR) capabilities; 
•  unmanned systems; 
•  language skills, regional expertise, and cultural awareness (LREC); 
•  operations to build partnerships with other countries and to expand partner 
capacities;

Navy Role in Irregular Warfare and Counterterrorism 
 
•  cybersecurity; and 
•  tools for fusing information from various sources. 
In addition, the Navy states that with regard to rapidly fielding IW new capabilities, specific 
current items of focus include the following: 
•  the Center for IW and Armed Groups (CIWAG)—an 18-month pilot project at 
the Naval War College in Newport, RI, whose current grant funding expires in 
June 2010; 
•  a large-diameter unmanned underwater vehicle (UUV) for ISR operations; 
•  Saber Focus—a land-based unmanned air system (UAS) that would be 
established in an overseas location and used for ISR to support IW operations; 
•  the use of ship-based Scan Eagle UAVs on converted Trident SSGNs for ISR 
operations; 
•  a surface ship- or submarine-based Maritime UAS that would be used for ISR 
operations and possibly signals intelligence operations; 
•  a naval intelligence fusion tool (NIFT) that is to integrate national and tactical 
ISR sensors so as to create real-time, actionable intelligence and targeting 
recommendations; 
•  a ship-based system called real time regional gateway (RTRG) for improved 
exploitation of signals intelligence to support IW operations; and 
•  an expansion in the size of helicopter squadrons that directly support special 
operations forces (SOF). 
Navy Counterterrorism (CT) Operations 
Navy CT operations including the following: 
•  Tomahawk cruise missile attacks on suspected terrorist training camps and 
facilities, such as those reportedly conducted in Somalia on March 3 and May 1, 
2008,18 and those conducted in 1998 in response to the 1998 terrorist bombings 
of U.S. embassies in East Africa;19 
•  operations by Navy special operations forces, known as SEALs, that are directed 
against terrorists;20 
•  surveillance by Navy ships and aircraft of suspected terrorists overseas;

Navy Role in Irregular Warfare and Counterterrorism 
 
•  maritime intercept operations (MIO) 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 
includes Navy participation in the multilateral Proliferation Security Initiative 
(PSI);21 
•  working with the Coast Guard to build maritime domain awareness (MDA)—a 
real-time understanding of activities on the world’s oceans; 
•  assisting the Coast Guard in port-security operations;22 
•  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;23 
•  protection of domestic and overseas Navy bases and facilities; 
•  developing Global Maritime Intelligence Integration (GMII) as part of Joint 
Force Maritime Component Command (JFMCC) and Maritime Domain 
Awareness (MDA); and 
•  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. 
The Department of the Navy stated in early 2010 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 (EMIO) 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.24 
Navy IW and CT Initiatives 
The Navy in recent years has implemented a number of initiatives intended to increase its IW and 
CT capabilities and activities, including those discussed below.

The Navy in July 2008 established the Navy Irregular Warfare Office, which is intended, in the 
Navy’s words, 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].” The office works closely with U.S. Special Operations Command, and 
reports to the Deputy Chief of Naval Operations for information, plans, and strategy.25 
Global Maritime Partnership 
The Global Maritime Partnership, initially known as the 1,000-ship Navy concept, is 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. The Navy states that 
There is no one nation that can provide a solution to maritime security problems alone. A 
global maritime partnership is required that unites maritime forces, port operators, 
commercial shippers, and international, governmental and nongovernmental agencies to 
address our mutual concerns. This partnership increases all of our maritime capabilities, such 
as response time, agility and adaptability, and is purely voluntary, with no legal or 
encumbering ties. It is a free-form, self-organizing network of maritime partners – good 
neighbors interested in using the power of the sea to unite, rather than to divide.26 
Partnership Stations 
The Southern Partnership Station (SPS) and the Africa Partnership Station (APS) are Navy ships, 
such as amphibious ships or high-speed sealift ships, that have 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-discussed global maritime 
partnership.  
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. 
The creation of NECC consolidated and facilitated the expansion of a number of Navy 
organizations that have a role in IW operations. Navy functions supported by NECC include the 
following: 
•  riverine warfare; 
•  maritime civil affairs;

Navy Role in Irregular Warfare and Counterterrorism 
 
•  expeditionary training; 
•  explosive ordnance disposal (EOD); 
•  expeditionary intelligence; 
•  naval construction (i.e., the naval construction brigades, aka CBs or “Seabee”); 
•  maritime expeditionary security; 
•  expeditionary diving; 
•  combat camera; 
•  expeditionary logistics; 
•  guard battalion; and 
•  expeditionary combat readiness. 
The Department of the Navy stated in early 2010 that NECC: 
Navy Expeditionary Combat Command (NECC) is a global force provider of expeditionary 
combat service support and force protection capabilities to joint warfighting commanders, 
centrally managing the current and future readiness, resources, manning, training, and 
equipping of a scalable, selfsustaining and integrated expeditionary force of active and 
reserve sailors. Expeditionary sailors are deployed from around the globe in support of the 
new “Cooperative Strategy for 21st Century Seapower.” NECC forces and capabilities are 
integral to executing the maritime strategy which is based on expanded core capabilities of 
maritime power: forward presence, deterrence, sea control, power projection, maritime 
security, humanitarian assistance and disaster relief. To enable these, NECC provides a full 
spectrum of operations, including effective waterborne and ashore anti-terrorism force 
protection; theater security cooperation and engagement; and humanitarian assistance and 
disaster relief. NECC is also a key element of the Navy’s operational Irregular Warfare (IW) 
efforts in the area of operational support to the Navy forces in OIF and OEF. In the FY 2011 
budget, NECC funding is increased to address increased requirements for NECC Global 
Force Management (GFM) presence, operational plans surge, and equipment life cycle 
sustainment. 
NECC provides integrated active and reserve forces, highlighted by the seamlessly integrated 
operational forces of naval construction (Seabees), maritime expeditionary security (formerly 
coastal warfare), navy expeditionary logistics (Cargo Handling Battalions), and the 
remaining mission capabilities throughout the command. 
NECC is not a standalone or combat force, but rather a force protection and combat service 
force of rapidly deployable mission specialists that fill the gaps in the joint battle space and 
compliment joint and coalition capabilities.27 
The Department of the Navy also stated 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 
Navy Expeditionary Combat Command (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 51% of Sailors supporting NECC missions, including 
Naval construction and explosive ordnance disposal in the CENTCOM AOR as emphasis 
shifts from Iraq to Afghanistan, 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.28 
Riverine Force 
The riverine force is intended to supplement the riverine capabilities of the Navy’s SEALs (the 
Navy’s Sea-Air-Land special operations forces) and relieve Marines who had been conducting 
maritime security operations in ports and waterways in Iraq. The riverine force currently consists 
of three active-duty squadrons of 12 boats each, and includes a total of about 900 sailors. The 
Navy established Riverine Group 1 (which oversees the three squadrons) at the Naval 
Amphibious Base, Little Creek, VA, in May 2006. The three current riverine squadrons were 
established in 2006-2007. 
As mentioned earlier, the Department of the Navy’s proposed FY2011 budget requests funding 
for “the establishment of a new RC [reserve component] riverine training squadron which will 
compliment the three existing AC [active component] riverine squadrons. The fourth riverine 
squadron will increase the riverine capacity to conduct brown water training and partnership 
activities in order to meet COCOM demands.”29 The Navy states that the creation of the fourth 
riverine squadron is to involve the realignment of 238 Full Time Support and Selected Reservist 
billets, and that the new squadron is to be the first-ever reserve component riverine training 
squadron within NECC.30 
Other 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, an intelligence data-mining capability at 
the National Maritime Intelligence Center (NMIC). 
Potential Oversight Issues for Congress 
Definition of Navy IW Activities 
Potential oversight questions for Congress regarding the definition of Navy IW activities include 
the following:

Navy Role in Irregular Warfare and Counterterrorism 
 
•  Should security force assistance operations, civic assistance operations, disaster 
relief operations, and counter-piracy operations be included in the definition of 
Navy IW operations? 
•  Should operations to build partnerships, and to build partner capacities for 
conducting maritime security operations, be included in the definition of Navy 
IW operations? 
•  Has the Navy included the kinds of operations listed in the two previous points in 
its definition of Navy IW operations in part to satisfy a perceived requirement 
from the Office of the Secretary of Defense (OSD) to show that the Navy is 
devoting a certain portion of its personnel and budgets to irregular warfare? 
•  Should the Navy’s CT operations be considered a part of its IW operations? What 
is the relationship between IW operations and CT operations? 
Navy IW Budget Priorities 
Potential oversight questions for Congress regarding Navy IW budget priorities include the 
following: 
•  Is the Navy’s list of IW budget items sufficiently organized and prioritized to 
support congressional understanding and oversight, or to permit Congress to 
know where any additional dollars available for Navy IW operations might best 
be added? 
•  Should items such as expanding Navy sea-based BMD capabilities, procuring 
DDG-51 destroyers, and Navy cyber security operations be included in a list of 
Navy IW budgetary initiatives? 
•  Are the Navy’s current IW-oriented UAV/UAS programs sufficiently 
coordinated? 
Degree of Emphasis on IW and CT in Future Navy Budgets 
A third oversight issue for Congress—an issue related to, but more general than the previous 
one—is how much emphasis to place on IW and CT activities in future Navy budgets. 
Supporters of placing increased emphasis on IW and CT activities in future Navy budgets could 
argue that the experience of recent years, including U.S. operations in Iraq and Afghanistan, 
suggests that the United States in coming years will likely need to be able to conduct IW and CT 
operations, that the Navy has certain specialized or unique IW and CT capabilities that need to be 
supported as part of an effective overall U.S. IW or CT effort, and that there are programs relating 
to Navy IW and CT activities that could be funded at higher levels, if additional funding were 
made available. 
Opponents of placing an increased emphasis on IW and CT activities in future Navy budgets 
could argue that these activities already receive adequate emphasis on Navy budgets, and that 
placing an increased emphasis on these activities could reduce the amount of funding available to 
the Navy for programs that support the Navy’s role in acting, along with the Air Force, as a 
strategic reserve for the United States in potential conventional inter-state conflicts.

Navy Role in Irregular Warfare and Counterterrorism 
 
Potential oversight questions for Congress include the following: 
•  To what degree can or should Navy IW and CT activities be used to reduce the 
burden on other services for conducting such activities? 
•  Are the Navy’s steps to increase its role in IW and CT partly motivated by 
concerns about its perceived relevance, or by a desire to secure a portion of IW 
and CT funding? 
•  Is the Navy striking an appropriate balance between IW and CT activities and 
other Navy concerns, such as preparing for a potential future challenge from 
improved Chinese maritime military forces?31 
Additional Oversight Questions 
In addition to the issues discussed above, the Navy’s IW and CT activities pose some additional 
potential oversight issues for Congress, including the following: 
•  How many Navy personnel globally are involved in IW and CT activities, and 
where are they located? How much funding is the Navy expending each year on 
such activities? 
•  Is the Navy adequately managing its individual augmentee (IA) program?32 
•  Is the Navy devoting sufficient attention and resources to riverine warfare?33 
•  Aside from the establishment of the riverine force and a reserve civil affairs 
battalion, what implications might an expanded Navy role in IW and CT have for 
Navy force-structure requirements (i.e., the required size and composition of the 
Navy)? 
•  Is the Navy adequately coordinating its IW and CT activities and initiatives with 
other organizations, such as the Special Operations Command (SOCOM) and the 
Coast Guard? 
•  Are the Navy’s recent IW and CT organizational changes appropriate? What 
other Navy organizational changes might be needed? 
Legislative Activity for FY2011 
The Navy’s proposed FY2011 budget was submitted to Congress on February 1, 2010.
