Oh, yeah definitely. My personal preps are one IFAK on each separate pack. So, I have one IFAK on my VEB, one on my GHB, one on my BOB, and one on my plate carrier. This way, no matter what's going on or how I need to separate/use my gear I have it. Of course, certain bags have additional med supplies depending on their use but that's my personal min requirement.Sorry tourniquets, combat gauze etc.
Could be a bit excessive material should the situation arise that I'm combining packs, but I figure some SERIOUS S*** has hit the fan at that point and those med supplies might come in handy at some point.
