I wouldn't know. I was in the US Air Force for four years, but we were only support. My job was loading nukes on airplanes, but this was back in the late 1950's. While stationed in Morocco, a large group of Arabs were charging our base on horses, and we were given our carbines for self-defense. However, about a few hundred yards from our base, they turned around and left. That was the closest incidence I had in the military. When we were loading nukes on the planes, we packed our 38's with us. If it became necessary, I suppose, I would shoot in self-defense. I don't think one actually knows how they will react under fire.
