My step grandfather was a barber from Ohio and a BAR man in the Pacific during WWII and he was a pretty tough old guy and a little mean at times. He said the Japanese would come in a bonzai attack charge and he would shoot them with a guy on each side of him feeding him magazines. The gun would get smoking hot and they would keep coming and coming. He had nightmares about that for many years and hated the Japs until the day he died in the late 1980s.
