Tourniquets and combat medicine
A Wall St. Journal article on advances in combat medicine notes that the tourniquet is making a comeback, with some troops carrying them strapped to their thigh for fast use.
The military ought to do more looking into BlackHawk's Integrated Tourniquet System uniforms. Tourniquets are actually built into the uniform, at shoulder, elbow, thigh and knee. Pull open a velcro pocket, and the strap and handle are right at hand.
