Russ Kotwal has that rare combination of action and documentation. The attached 9 page article is well worth the read for medics and anyone in a command/leadership position.
The Rangers managed no preventable death on the battlefield using TCCC (October 1, 2001 - March 31, 2010). The one cited was a post-op complication.
The case fatality rate in WWII where care was medic centric was 19.1%.
During Vietnam, it was 15.8%. 2500 of those from single extremity hemorrhage.
Today, warrior-centric care puts preventable death at 9.4%.
The Rangers are at 3% -- (again, that 1 that drove the % was post op).
Dr Kotwal ensured training to muscle memory and prepared his men well.
He also had the good sense to marry a phenomenally smart and fun wife Bari.
Just some background...
