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

Operation New Dawn
On August 31, 2010, President Obama announced that the U.S. combat mission in Iraq had ended.
A transitional force of U.S. troops will remain in Iraq with a different mission: “advising and
assisting Iraq’s Security Forces, supporting Iraqi troops in targeted counterterrorism missions, and
protecting our civilians.”1
As of September 28, 2010, six servicemembers have died in Operation New Dawn (OND). Also,
16 servicemembers in OND have been wounded and not returned to duty and 14 servicemembers
in OND have been wounded and returned to duty.2
Rates of Post-Traumatic Stress Disorder, Traumatic
Brain Injury, and Amputation

Post-Traumatic Stress Disorder
The U.S. Army Office of the Surgeon General provided the statistics below on the incidence of
post-traumatic stress disorder (PTSD) cases. 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 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. In addition, although the diagnosis of
PTSD occurred at some point after the individual deployed, there is no way to determine that the
PTSD resulted from an event associated with the deployment, that is, it could have resulted from
an event that occurred after return from or prior to a deployment.3
The Army has 67% of the cases, the Air Force has 9%, the Navy has 11%, and the Marines have
13%. Table 1 and Figure 1 present yearly PTSD diagnoses for all services.

a. Q1 covers January to March 2010.
Of the total 178,876 TBI cases since 2000, 137,328 have been mild, 30,893 have been moderate,
1,891 have been severe, 3,175 have been penetrating, and 5,589 have not been classifiable.4
Figure 2 shows the relative rates of mild, moderate, severe, penetrating, and not classifiable
TBIs.

4 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 hour; 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.
