Back in the day at AOCS, I saw a candidate bump a DI with his box during outposting. The DI went ballistic and had the guy convinced that if he didn't DOR on the spot he'd spend the next 20 years in Leavenworth for assaulting a superior. It was the only DOR I heard of getting reversed after another DI felt it was excessive since the candidate really didn't have an knowledge of the UCMJ and believed he was going to jail.
DORs back then were instant and final. It was also a game the DIs played. He with the most DORs won prior to commissioning won. They didn't stop trying until you were a candidate officer.
(I don't know what goes on at OCS today, but back in the early 1980s at AOCS outposting was when poopie week was over and you moved from the indoc battalion to your regular battalion (I or II). You had to carry all our stuff in a cardboard box that was about 4 feet long, 3 feet wide and 3 feet high. The box was carried in front of you at chest with your arms straight out and at chest height. It was very painful both to your muscles and to the skin as the box really cut into your arms. It also blocked your vision and made it almost impossible to walk without hitting things or stumbling. You circled the block 4 or 5 times on the way to the battalion with every DI at the AOCS having fun at your expense. It was a great spectator sport for Candidate Officers, newly commissioned Ensigns, Aircrew School guys and anyone else that just happened to be in the area. It happened on Fridays about 30 minutes after the outgoing class was commissioned so the new officers and their families/guest got to watch.)
