Well, first off, most folks know that QuikClot has now moved to gauze form over granules, which is the latest accepted for of treatment for wounds. Much easier to remove gauze than the granules, they moved to this about 3 years ago. The main issue they was having during combat missions with the QK before was in granule mode, there was issues with spill granules flying around when the helo came in for landings. Since its a thermobaric reaction, (when combined with any fluids, burns/cauterizes) warfighters were getting this stuff in the eyes and messing them up. It was easier to convert to quikclot impregnanted gauze to eliminate the granule issue.
The latest and greatest variant of granule you are probaby talking about is Celox, same thing, just not as harsh of a thermobaric reaction there isnt as much of a user penalty associated with using it. Myself, I carry all of them in my blowout kits.
