I read Col. David Hackworth's autobiography some time back ("Steel My Soldiers' Hearts) I'm sure if that man told me to charge a machine gun nest with a Bowie knife, I'd have done it. Anyhow, when trying to explain to a reporter or something what we were facing in Vietnam, he motioned over to a rifle butt sticking out of the dried mud (this had been the site of a battle some months before) pulled out an AK47 from the earth, shook most of the dirt off, squeezed the trigger, and proceeded to fire the remainder of its clip. Don't think tightly-engineered M16 ever do that
