I believe recruits should be exposed to tough but fair leadership. Unless a recruit has become violent, I see no reason for them to be "kicked like a football" or "slammed into a wall locker".
Making them do 100 pushups in the rain - no problem with that. But in general, there's no reason to be smacking these guys around.
Exactly, It is amazing how many people think we need to abuse people to make an army. These rules have been around for TWENTY years. I think the results speak for themselves. If a DI can't follow them kick 'em out. Rule breakers are no example for the new recruits.
