What constitutes being "old school" in the military?

Please...if you have to ask, you ain't old school.

AT EASE was a command to shut up.
All cotton uniforms were heavily starched.
PT was done in boots, fatigue trousers and white T shirts. In cold weather add a long john top and leather gloves.
1 May-30Sep was khaki uniform.
Fatigues were green, nametapes were white w/black letters, US Army tape was gold & black. All badges and rank were sewn on.
Shoes, boots and garrison cap peak/chin strap were spit shined.
M-1 rifle, BAR, Grease Gun, M-1 or M-2 Carbine. M-1919 series machine guns.
M-38A1 Jeep. M-37B 3/4.
Stand up Ridgeway cap.
Tent pegs and poles treated w/linseed oil.
NO 3 stripe Sergeant! (SSG E5)
Brown boots and a bottle of black dye.
You screwed up, someone took you behind the barracks and beat you up. Seldom an Art 15
40 man squad bays

To me, Old School is Brown Boots/Shoes and the M-1 Rifle.

If you ever got called to the 1SG's office and he was smoking a cigarette and had 2 burning in the ashtray....

Filling out forms in triplicate using carbon paper....

Ran up Longstreet in your jump boots, yellow, nylon Army swim/pt trunks & og tee shirt, waited at Green Ramp, Pope AFB like a tipped over turtle, for a lift off, pulled headcount at the mess hall & then had the best free-.75 cent breakfast in the world, maintained your individual assigned weapon with pride( while secretly wishing for an AK-47), wore your P-38 on your dog tag chain, stopped reacting to your first name, pulled duty (& other as assigned), went daily to the motor pool & did your best, went on field problems that became wars ...obeyed your order & if questionable in your mind, addressed it, Afterward, not before or during, & most of all kept a sunny disposition...nobody needs a "sad sack"~!

I'd like to try to explain my thinking. I don't think there's a moving line, I think it's a mater of when and where you served. When I was in most if not all the electronics didn't exist or was not available. We didn't have the luxury of looking though walls or putting a drone into play, we needed boots on the situation as a caller. Now, I think that the returning sailors and soldiers take for granted all the technology they have access to. Electronics to keep them stealthed, to fight from miles away just to name a few. Not to take away anything from those brave warriors of today, it was just a different time. I think the young bucks dont want to admit that we even exist and that's ok because they will get to where we are now. I just hope they have enough sense to not make the mistake and shut out their predecessors. Believe me, people will shut you out at a drop of a hat, you dont need to make it easier for them. Be strong, shake the hand of a Sr. vet, tell em how happy you are for him protecting your family and life. Now, watch the smile come over his face, the gratefulness. It's a great feeling.

When I hear old school about the military. I think about basic training where for a PT uniform as the olive drab pants, black combat boots and a white t-shirt instead of having a completely different PT uniform like the army has know is a good example of old school topic

Wearing TW's and garrison cap
Calling Rester Center or Carlisle Radio to enter the ADIZ
Knowing where the space in the road wheels and the bore evacuator are on a T-55
Listening to Chickenman on AFN
