The question is whether they were watered down for everyone so the gals could pass. For instance, a buddy of mine went through Marine OCS around the time of GW-I, and they could be ordered to do 100 push-ups at a clip at a moment's notice if their examiners had a whim to watch them do it. That kind of thing happened all the time. I would have thought the Ranger tab would be at least as "costly."
Officially, they do bends and whoopies or whatever until the Drill Instructor gets tired, bored, or they are vomiting up their socks.
Those who call them "D.I." not knowing it stands for Damned Idiot... It gets ugly.
