What constitutes being "old school" in the military?

Khaki "B"s and doing PT in fatigue pants, white Tee shirt and boots.

CSM Charles Hayden he was a professional when I was in grade school and I've been out of the Army for nearly fifty years,now that's old school goddamn it!

If you ever:
Drove or road in a 5/4 (precursor to the Gama Goat)
Used to raid and throw parts over the fence from the salvage yard to keep trucks on the road.
We used to run PT in boots.
Hid the extra inventory from the IG behind the Quanset hut walls in the shop.
Had counseling sessions in the battery room, you had respect whoever won.
Police call included fishing the drunks out of the drainage ditches.

If this was your uniform and primary weapon.

For me, being a Military Policeman, old school is those of us who carried the 95B MOS.

I suppose it's all a matter of perspective. To my Navy dad, old-school was wearing his crow on the right sleeve and a Donald-Duck hat with his uniform. To me, old-school Army was the long-sleeve khakis and Eisenhower jackets we wore in ROTC, qualifying on an M-1 and M-1 carbine, familiarization firing a .30-cal M-1917 machine gun, drinking from an aluminum canteen, etc.. Later on, it was short-sleeve khakis, qualifying with an XM-14A2, having fatigues with yellow and black US Army tapes and black and white name tags, and having a platoon sergeant with ribbons from WW2. To my mother, old-school would have been talking with the two elderly Civil War veterans who lived down the hill from her when she was a child. As I said, it's all perspective.

You may be old school if you were around when this thread was originally posted!!!! It happens that quickly :).

Seems like the term can float. Basically, "Old School" is a term used for those who wear digi/multi camo to describe the BDU/Tri desert wearers… and BDU wearers to describe the OD wearers… and the OD wearers to describe the…eh.. older OD wearers…. and the older OD wears to describe the M42/M43 wearers…etc… It's all perspective. We'll all be old school one of these days. Oh the joy

Old school if you ever used the flash-suppressor on a m-16 to break the bands on a pallet.

Every generation has it's "old school" so this is a moving target. A few fond memories:
Reporting for pay and having to make your way through your 1SG and CSM for whatever they were collecting for.
If the first military vehicle you drove was a jeep (or perhaps an Gama Goat, a CUC-V, or a "Duece and a half?"
When you fondly remember your P38 (can opener) as the wonder tool?
If you are Yukon stove or Potbelly stove qualified.
When you cooked, shaved and bathed with your steel pot?
Being able to fire your M16 (no "A" anything) on full rock-and-roll (auto, before three-round burst).
When you actually liked the Army slogan: "Be All You Can Be"
The days of M-Nu, Brasso, spit shining, ironing uniforms, melting wax to shine floors, 6-man rooms for permanent party, amongst thousands of other memories.
Don't forget the retired CSM trying to sell you a life insurance policy or a membership that "everyone" is expected to join.
Enjoy the here and now ... and then you can enjoy it later when it becomes someone else's "Old School."
