Overall Casualties in OIR, OIF, OND, and OEF

On August 31, 2010, President Obama announced that the U. S. combat mission in Iraq (Operation Iraqi Freedom, or OIF) had ended.1 A transitional force of U.S. troops remained in Iraq under Operation New Dawn (OND), which ended on December 15, 2011.2 (For more information on war dates, see CRS Report RS21405, U.S. Periods of War and Dates of Current Conflicts, by Barbara Salazar Torreon.) Several thousand U.S. civilian personnel, contract personnel, and a limited number of U.S. military personnel remain in Iraq carrying out U.S. government business and cooperative programs under the auspices of agreements with the Iraqi government. On October 15, 2014, U.S. Central Command designated new military operations in Iraq and Syria against the Islamic State of Iraq and the Levant as Operation Inherent Resolve (OIR).3

Operation Enduring Freedom (OEF) began on October 7, 2001, and is primarily located in Afghanistan. OEF is ongoing.

Daily updates of total U.S. military casualties in OND, OIF, and OEF can be found at the Department of Defense’s (DOD’s) website, at http://www.defense.gov/news/casualty.pdf. Table 1 gives the overall casualties in OIF, OND, and OEF.

Post-Traumatic Stress Disorder

The U.S. Army Office of the Surgeon General (OSG), using the Defense Medical Surveillance System (DMSS), provided the statistics 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 has, or had, PTSD. A single visit on record commonly reflects someone who was evaluated for possible PTSD, but did not actually meet the criteria for diagnosis.

All those who have been diagnosed as having PTSD during deployment were diagnosed at least 30 days after they deployed. However, it is not possible to be certain 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 OIR began after the cut-off date, therefore its numbers are not included.

Traumatic Brain Injury

Many statistics on traumatic brain injury (TBI) are available to the public at the Defense and Veterans Brain Injury Center, at http://dvbic.dcoe.mil/dod-worldwide-numbers-tbi. Unlike PTSD numbers, which are broken out by those deployed and those not previously deployed, TBI numbers represent medical diagnoses of TBI that occurred anywhere U.S. forces are located, including the continental United States.5 OIR began after the cut-off date, therefore its numbers are not included.


5 Defense and Veterans Brain Injury Center at http://www.dvbic.org/dod-worldwide-numbers-tbi. 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 30 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. "Not Classifiable" indicates additional incident information is required prior to TBI categorization.

Major Limb Amputations6

Table 4 shows the number of individuals with battle-injury major limb amputations for OIF, OND, and OEF. A major limb amputation includes the loss of one or more limbs, the loss of one or more partial limbs, or the loss of one or more full or partial hand or foot. The total number of amputations in OIF, OND, and OEF as of September 1, 2014, is 1,573. OIR began after the cutoff date, therefore its numbers are not included.

6 A previous update of this report included major and minor limb amputations. However, statistics on minor limb amputations were not available for this update.

--6--

From 2003 until the first quarter of 2009, the majority of the major limb amputations due to battle injuries 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 have occurred in OEF. Figure 4 charts the number of major limb amputations due to a battle injury in OIF, OND, and OEF from 2001 through September 1, 2013, for all services.

Self-Inflicted Wounds

According to DOD’s casualty website, as of November 5, 2014, 235 servicemembers died of self-inflicted wounds while serving in OIF and OND and 114 died of self-inflicted wounds while serving in OEF.7 Currently, there is no casualty summary by category for OIR.

Table 7 and Table 8 provide statistics on the race and ethnicity distribution of OIF, OND, and OEF casualties. All numbers for OIF, OND, and OEF are current as of November 5, 2014. Percentages do not total 100 because servicemembers may be listed twice, once under a race (such as "White") and once under an ethnicity (such as "Hispanic or Spanish").
