Quick question - I'm watching Where Eagles Dare right now for the first time. The actor the British use to impersonate a general who is really supposed to be a Corporal... He could be the grandfather of a Corporal. The real life actor was 59 when the movie came out. What were the writers thinking?
Theoretically, it's possible. Enlistment age max at the time was 37. But if you were already in the service, and were over that age, you remained. Possible for an enlisted man to have been in the Army and be around 60 years old. But to only be, or remain a Cpl. would have been rare. Could have been a clerk, cook, driver, ect.
Lot of older Sgt and Master Sgt in service at the time as they liked being that rank...lot of responsibility without the worry of being an ofc.
Also, back then, it took 5-7 support personal, who were enlisted, to support one fighting soldier. If you were in at the outset of WW ll, you stayed in.
Many, because of their patriotism, lied about their age, both younger and older, so they could enlist. Kids as young as 14 tried, and I'm sure that many grandfathers, who looked younger than they were, enlisted.
