If this former Marine is in his late 60s or older, his info may in fact be correct for his period of service. I'm not sure exactly when the US armed forces began measuring in metric, but I'm reasonably sure it was sometime between WWII and Vietnam.A former Marine told me that in boot camp, they sight in using feet, not yards or meters. I challenged him on this because I've never heard of anyone using feet to sight in. Can someone clarify this for me?
