Traditional OCS is more than just drill weekend. But I will start with that.
Friday: Arrive at the barracks after work. Set up your wall locker for inspection (you couldn't keep all of your equipment and uniforms there so you have to haul them back and forth). Report to the TACs if you are in leadership that weekend or if you had an assignment to complete, which we all invariably did (one candidate had a 15,000 word report of the Class A shirt). Get smoked a few times for good measure.
Saturday: Conduct APFT and must show improvement from last score, if not the TACs will ensure the entire class gets 30 days of PT in 2.5 days. Shower and dress for class, never enough time. Go to chow, eat square meals, get harassed by the TACs. Go to classes, take tests, get smoked. Evening, get smoked and harassed. Prepare for the next days inspection, good luck finding your stuff because the TACs have mixed everyones crap together in one big pile...again, they never get tired of that one. Peer evals sometimes. Some bizzare control game with the TACs. Get thrown out of the rack a couple times that night for more games and smoking.
Sunday: PT. classes, smoking, rinse, lather repeat. Go home.
Lots of fun. Glad I did it but wish I would have went accelerated.
