Uh oh, the reality of post Academy life would REALLY shock you then.
And yet somehow, over hundreds of years (at other academies, which all have similar physical traditions), great officers have been produced... some with far less delicate traditions.
Yes and lots of unprofessional officers have been produced. It's a lot of fun knowing your BC is banging his E-4 secretary or your married S-1 hooking up with one of the warrants. Or a COL who's up for BG getting court martialed for criminal activities.
