I have been in a group where a dozen people did not have a useful first aid kit for stopping heavy bleeding.
My medic was indeed trained by the Navy.
I actually carry a large first aid kit in my car (required for work) and one of the least available item was what we used to call a "battle dress", ie, a thick absorbant badage used for punctures, et al. None of the commercially stocked kits had them. I bought several boxes of female sanitary napkins, decided on the best one, and stocked all of the kits with them (along with wide stretch gauze rolls for finishing out the 'battle dress' bandage)
It is common theory in military circles that most wounds will be deep puncture, so this is the wound to be most ready for. In reading hiking accident statistics, I find that a majority of notable accidents involve the same types of wounds, so this is what I pack for (after all, a large bandage can be downsized for smaller incidents, but not so much in the reverse)
