What constitutes being "old school" in the military?

If you ever:
were transported in a cattle car
wore, washed, cooked in and ate from a steel pot
realized your M16 was built by the lowest bidding contactor
lived in WWII era barracks
actually put 2 shelter halves together to make and sleep in a tent
heavily starched your duty uniform or sent your uniform & civvie clothing to Quartermaster Laundry and everything came back with heavy starch
spit shined your boots
ran PT in combat boots, white t-shirt and heavily starched cotton fatigues
ate C-rations that had the 4-pack of cigarettes in the accessory pouch
and entered the military at least one day before me.

Old school when I was in meant the brown shoe army of ww2. I am considered one now! Spit shine black boots, starched and pressed fatigues, c-rats, cattle trucks and open bay ww1 & 2 barracks!

If you had c-rations with a 4 pack of cigarettes that when you light them they lasted about 20 seconds
you are old school.

March 1964 at MCRD San Diego CA. I got the pleasure of sleeping with my M-14 rifle, not because I dropped it but because I couldn't remember the serial number when the D.I. asked me and now 55 years later I can still remember its serial number!

Your old school Marine when you
1. Painted liquid starch on your cover, then used a hot iron to make it stiff.
2. Ate C- Rations in the field ( MRE'S didnt exsist)
3. Had to wear solid green utilities like Gomer Pyle, cammie were not authorized yet.
4. When the only means of communication was a paper, pen, envelopes and a postage stamp or if your lucky a pocket full of quarters and a pay phone.
5. M-16 basic rifle, flack jacket bayonet, a.l.i.c.e. pack, Korean war era jeep for transportation.
6. Sent to fight with a compass and map. No GPS, no satellite or landsat communications. No infrared googles or glasses, no electronics whatsoever only prc-77 and old school jeep mounted radio gear.
Sleep in actually tent that you only had 1/2 of until you found another marine to bunk with.
7. No one was gay or confused about their sexuality or change of life. If they were, it was discovered real quickly. We had standing orders on what to do if we found any Marine in the wrong position with another marine.
8. What's a Drone ?
9. P.T. was Red shorts with gold trim with the Eagle Globe and Anchor stamped on the lower left front side, white T- shirt and sneakers ( No Nike ) .
10. Everyone cursed and yelled at you, from boot camp until you made E-4 . Unless you were a total idiot, then you got yelled at until you got it.
11. Hand to hand training was just that ! Not wrapped in bubble wrap and helmet

If you wore fatigues O.D. Green, slept in WWII barracks and wore a steel pot, you're old school.

Got paid in cash on payday....

In basic, you were issued two pairs of boots, which you rotated daily. You broke them in (and destroyed your feet) by doing all of your PT in them. The tennis shoe was only a dream at the time. If you wore yellow PT outfits and wore tennis shoes, you are not old school.

Don’t forget eating C-rations and using a P38

Guess my dad (WANG 1930-38, USA 1942-71) would qualify as old school. I didn't serve until the early 1970's.
