Reference the Army's Combat Lifesaver (CLS) program for non-medics, that actually has been around for better than 20 years.
It started back in the early to mid 80's...I remember being tasked to set up the first CLS course at Ft Lewis waaaay back when (1985) when I was a Medical Service Corps 2LT (and a medical platoon leader in an infantry division).
Lots of troops are alive today because of that particular Army program.
FWIW, I guess I could have asked my daughter. She was a captain in the (Army) Medical Service Corps -- and one of the few women (at that time, at least) with the EFMB (Expert Field Medic Badge). Now she's a civilian EMT, Paramedic, and PA (Physician Assistant) -- and a (2X) mom...
