It's all relative. My swab summer was worse than current swab summers. The stories I've heard from classes from the 1960s or 1980s are worse than what I experienced. I had a member of the class of 1974 lecture me on a Metro ride about how much hard it was when he went through, and how it has affected the quality of new officers (to be fair, he seemed fairly disgruntled... and I was out so it didn't have the desired effect).
Visiting CGA last year, one of my old cadre told me "LITS, if we did today what we did to you, there would be a Court Martial." Granted, I had it pretty bad (some of that badness was earned).... but that's a fairly telling statement from someone who was there as a cadre, and is now there as a company officer.
At my first unit I was "counsel" for a prospective Chief, in a Chief's Initiation.... (now they call it something else).... it was just before the real "tone it down" movement came. I won't ruin what it's like, but my nickname was Dirk Diggler and i looked like a pretty cool porn star (clothing on folks.... I remained fulled clothed!). There are photos.... somewhere...
If there's anything worse than being a young junior officer, acting as counsel, it's being a chief warrant officer at Chief's Initiation (well.... maybe not, but those CWOs really got made fun of).
Even traditions like "Crossing the Line" have changed.... go to Youtube and look up "Shellbacks" or "Pollywogs" or "crossing the line" or all of the above and watch the crap they did back in the "black and white" days. Yuck.
Much of what we did will FEEL like hazing to folks who haven't seen it, don't understand it, or choose to be sensitive to it. For the folks who endured it, it's just part of the process, and it's a future story....
