Conclusions
By the way, there actually IS a neat new system for stopping bleeding deep in the abdomen. Its not super effective with fragmented 5.56 rounds, but it does work way better than surface applications and pressure. Its called the “Celox A” applicator, and its basically a long plunger to get hemostatic granules deep into the wound. 30$ a pop though.
