I’ve been busy. Excuse me. I’ll state that the judge might say, “Hey, you can always join the military instead of me throwing you into the slammer.” As I’ve already posted, there was a fairly recent case of that. The outcome: the military itself says we don’t do that. So, I already did respond to the cogent bit. In short: one cannot be ordered into the military instead of jail, unless of course the jail bit is for refusing conscription.
I seriously doubt the person’s story that he had that option in 1984. The military wouldn’t take him while trial is pending. Now, if he’d already had the trial, was on probation, then enlisted with a waiver, that’s not “choosing the Army over jail,” now is it?
And since it didn’t happen in 1984 (I just re-read that post), that’s not really the case anyway. The poster said “1970s” and I pointed out later that “1972 ain’t 1979.”
Recently the UK army (and/or Airforce) had a slight embarrassment as they shipped some 17 year olds out to Iraq - I vaguely remember that they were weeks off 18.
