I've had this discussion before. If you're pinned down, and leaking bad, and alone...You are in a bind if you can reach your compression bandage or not.
I forget all that's in there -- Izzy, Kerlix, maxipad, tongue depressors, tape, and some other shit. We're typically not pinned down by accurate depressed enemy fire, so it's usually OK to use your trauma kit and WFR or WEMT on the other guy. I'll replace all that shit for you, bro.
My vest already weighs 20 lbs if I have to hang a logger's tape on it. When clients and inspectors see a red & white first aid kit festooned with reflectotape, a man's name, and his blood group, they know we're the guys Strawberry gets the good shit from.
