U.S. Military Casualty Statistics: OND, OIF, and OEF

Current Operations
On August 31, 2010, President Obama announced that the U.S. combat mission in Iraq (Operation
Iraqi Freedom, OIF) had ended. A transitional force of U.S. troops remained in Iraq under
Operation New Dawn (OND), which ended on December 31, 2011.
As of May 7, 2012, 4,409 servicemembers died in OIF and 31,924 servicemembers were
wounded in action. In addition, there were 40,241 non-hostile-related medical air transports.1 In
OND, as of May 7, 2012, 66 servicemembers died and 301 were wounded in action. A further
2,516 required non-hostile-related medical air transports.2
Operation Enduring Freedom (OEF) continues in Afghanistan. As of May 7, 2012, 1,951
servicemembers have died, 15,858 servicemembers have been wounded in action, and there have
been 16,196 non-hostile-related medical air transports in OEF.3
Rates of Post-Traumatic Stress Disorder, Traumatic
Brain Injury, and Amputations

Post-Traumatic Stress Disorder (PTSD)
The U.S. Army Office of the Surgeon General (OSG), using the Defense Medical Surveillance
System (DMSS), provided the statistics below on the incidence of post-traumatic stress disorder
(PTSD) cases. According to Dr. Michael Carino of the OSG, a case of PTSD is defined as an
individual having at least two outpatient visits or one or more hospitalizations at which PTSD
was diagnosed. The threshold of two or more outpatient visits is used in the DMSS to increase the
likelihood that the individual actually had PTSD. A single visit on record commonly reflects
someone who was evaluated for possible PTSD, but did not actually meet the established criteria
for diagnosis.
For those who have been diagnosed with PTSD during deployment, although the diagnosis of
PTSD occurred at least 30 days after the individual deployed, there is no way to determine that
the PTSD resulted from an event associated with the deployment. The PTSD could have resulted
from an event that occurred prior to a deployment.4 Table 1 and Figure 1 present yearly PTSD
diagnoses for all services.

U.S. Military Casualty Statistics: OND, OIF, and OEF

Traumatic Brain Injury (TBI)
Of the total 233,425 traumatic brain injury (TBI) cases since 2000, 178,961 have been mild,
38,943 have been moderate, 6,188 have been severe or penetrating, and 9,333 have not been
classifiable.5 Table 2 and Figure 3 show the relative rates of mild, moderate, severe, penetrating,
and not classifiable TBIs.


5 Defense and Veterans Brain Injury Center at http://www.dvbic.org/TBI-Numbers.aspx. The DOD categorizes TBI
cases as mild, moderate, severe, or penetrating. Mild TBI is characterized by a confused or disoriented state lasting less
than 24 hours; loss of consciousness for up to thirty minutes; memory loss lasting less than 24 hours; and structural
brain imaging that yields normal results. Moderate TBI is characterized by a confused or disoriented state that lasts
more than 24 hours; loss of consciousness for more than 30 minutes, but less than 24 hours; memory loss lasting
greater than 24 hours but less than seven days; and structural brain imaging yielding normal or abnormal results. Severe
TBI is characterized by a confused or disoriented state that lasts more than 24 hours; loss of consciousness for more
than 24 hours; memory loss for more than seven days; and structural brain imaging yielding normal or abnormal
results. A penetrating TBI, or open head injury, is a head injury in which the dura mater, the outer layer of the system
of membranes that envelops the central nervous system, is penetrated. Penetrating injuries can be caused by high-
velocity projectiles or objects of lower velocity, such as knives, or bone fragments from a skull fracture that are driven
into the brain.

U.S. Military Casualty Statistics: OND, OIF, and OEF

From 2003 until the first quarter of 2009, the majority of the major limb amputations due to battle
injuries in the Army occurred in OIF. In the second quarter of 2009, however, the trend changed,
and since that time the majority of the major limb amputations due to battle injuries in the Army
have occurred in OEF. Figure 4 charts the number of Army major-limb amputations due to a
battle injury in OIF/OND and OEF from January 2009 to June 2011.

hostile action or terrorist activity, such as casualties due to the elements, self-inflicted wounds, or combat
fatigue.
Operation Enduring Freedom
According to DOD, a total of 21,047 individuals were medically evacuated from OEF from
October 7, 2001, through May 7, 2012. Of the total number of medical evacuations, 16,196 were
