When I was in basic (1979) they had a rule against the use of profanity. I don’t recall either of our TIs ever using the F-word, although a few other four-letter words slipped out from time to time. This applied to us as well. We we’re allowed to say those words either.
Glad to hear they’ve relaxed that rule. It just didn’t seem like real basic training without being cussed out by the sergeant.
That pretty much resembles things from 1989 as well. But really, you don’t have to drop the F-bomb; there are lots of creative ways to make you feel miserable and denigrate you!
