Combat medicine tends to be more quick and (no offence) dirty. you don't have time to play around with layer after layer of gauze on continuous bleeding, you throw a tourniquet 2 inches above the wound and tie it off. you don't have the luxury of a 30 min hospital ride, your nearest mash unit might be 3 hours or more away. I understand that well enough, seeing some of the equipment and shortcuts my dad had the ability to use in the army, instead of the civilian gear and regulations was eye opening. ill change it around.
