What constitutes being "old school" in the military?

Serving on the border of East & West Germany in the late '70s and waiting for THE BALLOON TO GO UP. Pulling SDNCO at 11th ACR HQ and receiving coded messages from USAEUR throughout the night, then Bingo, you get one that trips the alert siren! Not knowing if it's a test or for real, going through the motions to put the Regiment on Alert, including setting the 'cack code' gun for the Crnl's bird, running it up to the airfield, and keying the transponder on his chopper; then joining your own unit after being relieved, pick up your steel pot, LBE, Ruck, weapon and move to your assigned position on the fence.
Dependents would be prepared to move out. Usually, the sign that it was just a drill, was whether or not they were actually moved. I recall one time witnessing them being loaded up and the busses moving. We thought for sure this was the real thing! Fortunatly someone at USAEUR thought they would take the alert to the next level as part of the test. Sure fooled us for awhile!

Standard issue Springfield M-1903. That's old school in anybody's book!
Miss you, dad!

The Continental Soldier is the true example of OLD SCHOOL. NEW SCHOOL is the ability of our leaders, in todays Army, to train our soldiers to sacrifice their individualism for that of the mission before them. In every Unit, at all levels of Command, this should be posted: Soldier are you prepared to go into battle today? You are carrying on for The Continental Soldier. "THIS WE WILL DEFEND, YORKTOWN 1775".

Old school is a a style of soldering that were doctrine in the past. It is or was the old ways of doing thing such as changes in disclipine, changes in regulations and most importantly, policies changes.

Old school was getting the hell beat out of you by your platoon sgt inj basic. Later, the Army designated a Platoon Guide who did it for the sarge.

You are school of you fix bayonet for Change of Command Ceremony only to see some poor battle buddy, a guy from the other platoon, got sliced while passing out from attention.

Having been issued a "U.S. Rifle Cal. 30 M-1 as your primary weapon would qualify as "Old School" to me.

Old School? Yes in 1974 it was M151, the gama Goat, a duce and a half my dad drove, tailored OD Green, Cockern jump boots, C Rats with your P-38 ( i still have mine ) M3 45 cal burp gun. and a whole list of other stuff In my 40 years of duty I saw a lot of changes

Old school is when you are standing in a parade formation in lbe and the bn commander keeps coming back to you a rechecks your your uniform three or four times. Then it dawns on you that you are the only person wearing canvas lbe

Every older soldier active, retired, whatever has a tendency to look at the newer soldiers and say sadly that they're just not as smart, tough, STAC (that's old school for you) sharp, and so on as we were. Yeah, sure, right. The important part of old school is the ethic of soldiering, and that is passed on through traditions, guidance and role models. Loyalty, honor, taking care of your sisters and brothers, not being selfish, not being greedy, not being lazy...that's old school. We prefer the way it was when we were...but what's important and has been important for over 200 years and 10000 years for the profession, is what made us what we were and are. That's the old school.
