Not sure where you are located. Maybe your son is thinking about long-term job security and retirement bennies.
I know a fine young man, quite conservative who became a town constable [small village here]...wanted to get into the state police....went to Norwich. His excellent marksmanship abilities got him drafted to the AFT [argh! I know] but as far as I know, he hasn’t been laid-off from his job. And has a decent pension to retire on.
Norwich University, Northfield, VT
If he is interested in that, I am a grad. I also know some kids there. I would be happy to help any way I could. And they have civilians there now. Although, the Corps of Cadets is the reason to be there.
