Causes of death in US Special Operations Forces in the global war on terrorism: 2001-2004.

INTRODUCTION: Effective combat trauma management strategies depend on an understanding of the epidemiology of death on the battlefield, resulting in evidence-based equipment, training, and research requirements. METHODS: All Special Operations Forces (SOF) fatalities (combat and noncombat) in Operation Iraqi Freedom/Operation Enduring Freedom (OEF/OIF) from October 2001 until November 2004 were reviewed. All available autopsy and treatment records and photographs were used. In most cases, the immediate tactical situation was unknown. The review was performed by a multidisciplinary group including forensic pathologists, an SOF combat medic, and trauma surgeons. Fatalities were classified as having wounds that were either nonsurvivable or potentially survivable with existing training, equipment, and expertise on the battlefield. A structured review was performed evaluating the need for new equipment, training, or research requirements. Results were compared to autopsy data from Vietnam and modern civilian trauma center data. The study was approved by the Institutional Review Boards of the Armed Forces Institute of Pathology and the US Army Institute of Surgical Research. RESULTS: During the study period, 82 SOF fatalities were identified. Autopsies were performed on 77 Soldiers. Five casualties died secondary to aircraft crash, their bodies were not recovered from the ocean. For the purposes of this study they were considered nonsurvivable. Eighty-five percent (n = 70) of the fatalities sustained wounds that were nonsurvivable, while the remaining 15% (n = 12) had wounds that were potentially survivable. Injury Severity Score (ISS) was higher in the nonsurvivable group (p Language: en
