The OP's video was shot after my time. They were wearing two-piece poopy suits. Ours were heavy cotton one-piece weapons of discomfort.
I was in RF-2, the second class to try a new system. 10 days in Indoc, wondering what the hell we had gotten ourselves into, then half of the pilot candidates were immediately sent to Saufley for Primary, along with a class officer and a DI. No ground school, no commissioning, nothing but the firehose of primary and a DI along to make sure we would get dicked over on a regular basis. We were still shell shocked from Indoc when we started, and we were competing with everyone who was commissioned and who had completed Flight Systems (ground school). Tough competition.
The other studs didn't know what to make of us. The AOCS guys were universally pricks to us, the Academy guys were still in their casually arrogant phase, and the Marines were all really cool with us. After primary, we got a "Solo Bar" to wear over our name tag, then back to AOCS.
I don't know how long this experiment went on for, but we sure thought it was a very unfair way to do things.
