My dad, John Sr., attempted to join the U.S. Marines in 1943 when he was still 15 or 16. Like a lot of boys at that time, he lied about his age and I believe used his older brothers birth certificate to enlist. Some got away with it and no doubt the military did not scrutinize too closely as long as you appeared able to hold a rifle. Guess I have to give him credit for trying and he did make it through basic at Parris Island. Dad never spoke about it much but the Corp. either finally realized the mistake or he did something stupid (most of us did at 16) to get himself tossed out...not sure which. I am trying to find some records but no luck so far.
