Need to dial in the O2 and IV part, but we have IFAKs and full kits in every vehicle.
When I was in Iraq, the lead for one of the USAF units with frequent outside the wire adventures had two tourniquets on his vest and an extra in his IFAK for four total on his person.
When I asked him why, he said, "I'm wearing the armor because I expect incoming fire. I have the tourniquets because some dumb a$$ might actually hit me and I don't want to bleed out.
We carry lots of those, too.
I also have an extensive first aid kit in every vehicle as well as an IFAK on every vest. Quick clot, tourniquets, SCW HyFin vents, pneumothorax decompression needles, etc are part of every kit with O2 and IV therapy in my big bag. I’m responsible for mine and my family’s safety and since I’m trained in the proper use of such equipment I would be irresponsible to not avail myself of every advantage.ymmv
