Thanks. API DID exist back then, but only ROTC/USNA bubbas did it. We did all that stuff, but it was part of our program. If I recall, we had some faster minimum times, but hell, those guys were Ensigns already, so they shouldn't have had to prove themselves. My guess is they called it a "C-Course" because it was a bit like a cross county run. Some asphalt track, some tree-lined hard packed ground, and (ugh!) a bit of sand.
By far, the best time at AOCS was the beer run. It was a good hard run (5-6 miles) in formation, singing Jodies, with a trashcan full of cold beer at the end. Did one about every 3-4 weeks. The worst was the rifle run. 1.5 miles doubletime with our rifles at order-arms and singing too. It was one of those "weedout" things. If you didn't finish with your class, you dropped down a class.
I've heard some GREAT stories from AOCS. It sounds pretty intense. Although from what I've heard OCS nowadays is more of a mindfvck than AOCS was back in the day. It seems more like if you couldn't hack it, you rolled or were gone, whereas nowadays, even if you're in the middle of the pack they still make you feel like you're gonna "go away" if you slip one bit. Great memories...
