A decade of intense combat in two theaters has taught us many lessons about what works and what does not in the effort to accomplish that all-important mission of saving lives in battle. A severely injured Soldier today has about twice the likelihood of surviving his wounds compared to Soldiers in wars as recent as Vietnam. That progress is the result of many things: better tactics and weapons, better body armor and helmets, better trained and fitter Soldiers. But, the introduction of tactical combat casualty care (TCCC) throughout the Army has certainly been an important part of that improvement.
