Greatings Ladies and Gents; IMO, if you carry personal defence weapons or are in an environment that you might be exposed to said weapons or feel that your FAK would be used to treat others, then it must include supplies to manage (at least remedially) more then a "booboo" kit can handle. With the requisit knowledge,the kit is designed to treat life threatening injuries until more/better arrives. On the street, at the range/class, or while hunting ect., the need is the same as on the battle field. You need to be able to keep yourself or another alive long enough to get to an ER or for EMS to arrive. I think these kits are called "blow-out" kits, and I've seen recomendations that everyone that goes about armed add one to their EDC. Do a web search and you'll find kits of all sizes, shapes and descriptions, Jim
