What constitutes being "old school" in the military?

Wearing 1505's and carrying a .38 in a leather holster

I wore no PT belt and never rode in a truck. I drilled with an 03A3 that the bolt had been welded shut. But I went through GLNTC in 1960 and that makes me "Old School".

Knowing what a P38 is and what the purpose of it exactly is. 1. Handy-dandy middle of the night screwdriver. 2. Open any tin can. 3. Great nostalgic conversation starter. 4. C-rats can opener. 5. All of the above.

Knowing the term"BC glasses" at BMT.

Old school is any time one day after you joined. Anybody who was in before that is old school. Anybody one day after that is a newbie and has it easier than you do.

You're Old School if you have a hard time navigating this web-site.

Issued green fatigues
Used C rat cans to make a early warning
Ate John Wayne bar
Had quanson hut for barracks
...with grey metal bunks, wall locker, desk and chairs
Ate from a mess kit
Drank and shaved from a water blivet

It ended with the end of the steel pot

In Korea in 1960, having to purchase and wear those stupid pillbox caps (no way to fold them up and put them in your fatigues pockets) and purchase and wear those damned silly dickies.
