Virgil: I went through BAC in 1951 and on completion went to an Airborne Ranger training with a Ranger Company. I can remember a 'trooper who spit in the plf pit (sawdust filled.) The Cadre made him pick up his spit with his mouth and run around the compound until they let him stop and put him in the lean & rest until he collapsed!
Let's put it this way when in mid-85 I went to Airborne School on Ft Benning they'd just ended the ability of the cadre to physically hit you, shortly after my stint they stopped sending trainees to the 'pit' for punishment in the Georgia heat, in '87 the first female cadre was brought on, running shoes were substituted for combat boots during PT (probably a good thing) and so on.
Army airborne training is just a cattle call now, a shadow of what it once was during the Vietnam era.
