Sorry I missed those reports. I have only recently discovered the joy of SWAT
and so I can only reference recent articles.
I will indeed check with the corpsman who gave us the period of instruction, as well as those in my unit who've BTDT to see if they've ever used the stuff. The doc who was giving the talk couched the explanation in the first person and claimed personal experience with the product in combat.
Obviously someone in this equation is either lying or wrong. I can only hope it isn't the person tasked with patching my sorry arse up.
