I don't know or care which specific branch he went to. The point I make is that he had to enlist as a way out and to fund his studies, he wasn't some dude born with a silver spoon.

Don't care about the distinction between them either, or their subdivisions. Most of the times I call all of it "the army" (as in armed forces) anyway, chalk it to dyslexia if you wish.

That's not how I've heard him tell it.
