What constitutes being "old school" in the military?

I remember beer machines in the dayroom.

Old school is a scape goat for "I don't like this change" and/or "I refuse to evolve."
Anyone that tries to hold onto "Old school" is irrelevant in there current mind set and should seek grow as a leader and as a human. Change is inevitable, if you think complaining about it is going to do anything to fix it than step aside. If you don't agree with the change, first try and learn the "why" behind it. Second, if you still don't agree with it run it up the chain.

As a patriotic civilian, this topic, "old school" has to the best companion to this 1st cup of black coffee on this fine day in our LAND. Thanks 4 the entertainment. Woodstock generation granny.

Don't forget the P-38 can opener on your dog tag chain that would open and stab you!

Black boots & BDUs in the closet.

Old school was extremely verbal and almost always physical. I can give you a couple of samples. In Old School not much constraint was used in barking orders and you would have t jump run talk or it could become very physical very quickly. Example in the navy the cut off time was called rocks and shoals. Meaning that differences were physically discussed behind the after stack and whoever walked out was the one who was right, irregardless of rank or stature. The Navy ended that. Navy boot camp of which at this time I was attending we were required to wear leggings or spats. A politicians son developed blisters and the practice of leggings was done away with. In my opinion it was politics that did away with Old School. Now no harsh words or treatment only talk, discuss, convince a person to do something other than a direct order / or else. EVEN SO WE ARE STILL THE BEST MILITARY FORCE ON EARTH. ET- PO2 / SGT / TRAINING NCO /PATHFINDER /CB /BOSN. /COXSWAIN /HVY EQUIP OPER / PLOTTER /HELMSMAN / MACHINERY REPAIRMAN / INFANTRY.

Knowing the true definition of "Wall to wall"counseling, spit shinning boots, pinning on rank, getting smoked, grey PT gear.
