What constitutes being "old school" in the military?

Issued OD green fatigues, and ran ALL PT, in boots. I didnt see a PT uniform until I went to Korea. And didn't start running in running shoes, until 83. Class A uniform was with a sort of tan colored shirt, until, and wasn't issued BDUs until 83. Some SF guys were privates,( myself included) and we earned the beret flash, the tab came later. Ranger wore black berets, and we didn't have to wear helmets when in the field, unless the mission commander required it. Beer and cigarette machines in the barracks, and yes we lived in barracks, not dorms. Most importantly, you respected EVERYONE, above your rank, and did as you were told.

Ever eaten C rats

Riding in a CUC-V.

Strippers at the Officers Club.

Starched uniforms and spit shined boots

Cleaning latrines with Ajax and brown paper towels.

Sexually charged and foul language jody calls.

Always carry a P38 with your dog tags.

Boots without "speed lace".
Waited on line to get paid.

Your LES was green.

Your enlistment paperwork had carbon copies.

No such thing as Velcro rank insignia

I've eaten C-rations, K-rations (survival), LRRPs, and finally MREs. (C-rations were the best - especially if you got a can of peaches) Did PT in combat boots, fatigue pants (bloused), and t-shirt. Had no idea of the term "kinder and gentler". Yes - rode/drove in a real deuce and a half, rode M-113 APC, and drove the old Willys jeep (called a M-151 back then). Did land navigation without GPS. I recall when the B-52G was "new", and flew in a C-123 Provider. Used an M-16 without forward assist (as well as the GAU5/5A folding stock version). Carried a .38cal revolver instead of a semi-auto sidearm. I even remember Air Force khakis though those went out as soon as I signed up.

C-rats. I miss them.

Old school to me was when those underneath you needed disciplined you didn't ruin their career . You kept it in house took care of it yourself and hoped you saved someone's career from a petty offence .

If you remember a time when if you chose to smart mouth someone you better be able to back it up. Cause the 1SG wasnt going to care about your fat lip.

If you were issued a shelter half but no posts or stakes. At some point during the night you just rolled up in the canvas and collapsed. Sleeping bag? Ha! Don't make me laugh.

Your poncho smelled like sour milk and most of the time was your only shelter from the rain.

If you remember a time when there were light green marines and dark green marines, but we were all green.

If your first EO brief was from a 1SG with a cigar clamped in his teeth whi admonished the company that... There a female joining the unit, you watch your damn mouths and keep your dick skinners to yourself.

Having enlisted in 1954, retired in 1985, then taught aerospace science for AFJROTC the next 24 years, I think I qualify for "old school".
