My dad used to point to that scene and say “there I am.” He’s one of the soldiers marching in that scene shot at Fort Lewis in Washington state. He realized that there’s no way he can tell which one he is in the formation but he is one of them. He was in Audie Murphy’s former platoon at the time as Murphy was medically retired several years earlier due to war wounds. My father did get to meet Murphy as he was there for filming.
“How close is the enemy to your position Murphy?”
“Hang on! I’ll let you talk to them!”
