Tactical Combat Casualty Care (TCCC) has saved hundreds of lives during our nation’s conflicts in Iraq and Afghanistan. Nearly 90% of combat fatalities occur before the casualty reaches a Medical treatment facility, it is clear that the prehospital phase of care is the focus of efforts to reduce deaths in combat. Very few military physicians, however, have had training in this area. As a result, at the onset of hostilities, most combat Medics, corpsmen, and para-rescue personnel (PJs) in the US Military were trained to perform battlefield trauma care through the use of civilian-based trauma courses that were not designed for the prehospital combat environment and did not reflect contemporary knowledge in this area.
