I can't point to any specific source (yet) for the info, other than my instructors - most of whom were Army or AF medics, or Navy corpsmen. We were taking PHTLS, TNCC, or ATLS depending on our provider level, so a higher echelon of care (for the most part) than what the medics are getting. I'll see if I can dredge up some references in the next couple of days on this info.

One thing I realized - there's something called "Combat gauze" still being used by the military that's apparently a QuickClot product with impregnated propriarity anticoagulant. That's still in use/approved. This is probably what you're talking about.

I have yet to see a tourniquet in civvie use, but in all fairness I've been off the streets about 5 years now.
