The Army came to my highschool my senior year and put on an exhibition. They had Humvees and APCs and a massive wall of speakers that would make a passerby deaf at 40 yards. You were able to get out of class if you went to the event and listened to their pitch. I was one of like 4 kids who didn't go. Parents weren't told about this in advance, and there were recruiters there with pens waiting.
TBF, my school did have JROTC program but still... I think thats what set off my long history of being anti-that.
