More medical reports indicate that the new Interceptor protective vest was, indeed, bullet proof. Only nine percent of the combat wounds to 118 army casualties were in the trunk, and these were either by larger caliber weapons or shots that came in at odd angles and got around the Interceptor (like via an armpit.) Autopsies of 154 dead soldiers showed that the single most common area hit was the head (neck and face, the rest is well protected by the Kevlar helmet.) The next largest category is multiple wounds, including ones that sever major in the arms, and most dangerously, in the legs. The marines, who were always more willing to wear the protective vests (in Vietnam, this is thought to have saved the lives of at least a thousand marines), soon discovered that the 16 pound Interceptor, with ceramic plates, did indeed stop bullets. After the first few marines took a bullet in the chest (plate), got knocked down, then got up still full of fight, the word got around real quick.
