Chaos... sorry, I should have prefaced that it was immediately after Columbine in 1999 (pushing 20 years ago)... at the time data learned on battlefield survival from the GWOT on the use of tourniquets was not widely available... and the old "don't use a tourniquet" by un-trained individuals was pretty common... I had good information from a friend at SOCOM at the efficacy of tourniquets, but at least I got the Kerlix included to pack off wounds, and the petroleum gauze for a pneumo thorax... I've been retired 9 years, and I hope they are still in place, and have been upgraded... thank you for your concern
