The thing this ex marine appeared to struggle with was the continuous beastings, he was a good recruit, kept his gear in good order & did what he was told, however others in his billet were pretty useless. He was constantly getting his stuff thrown out of the door along with the other's belongings due to someone else not stowing their stuff correctly, having to do loads of extra menial chores for things which weren't his fault & generally being treated like crap when he was actually doing well. Apparently this ground him down.
