I started out in AFROTC in college, with the goal of becoming a navigator. I worked hard and got "promoted" within ROTC. At the end of my freshman year I applied to take the nav aptitude test and was not allowed to because I wore glasses, despite that not being mentioned as a problem when I joined ROTC.
During my junior year I applied to the surface Navy. No go -- glasses. I then applied to the Coast Guard. No go -- glasses. One day Naval Air came to campus and I was sort of mooning around the display when an ENS (on recruting duty waiting to start flight school) said 'hi.' We started to talk and I told him I was working toward my private pilot's license and naval aviation looked like great duty, but since I wore glasses I realized that I couldn't qualify as a Navy navigator. He said, 'well, take the test; what have you got to lose?'
So I did well on the flying aptitude test (despite my major being Anthropology) and then I went to NAS South Weymouth for my flight physical and they said 'sorry, your vision is above the 20/50 minimum.' At that point I started to get pissed at not being accepted by the military despite my wanting to serve so I reapplied. Again, no. So I re-re-applied. At my third flight physical the flt surgeon wrote, "eyes 20/100 but motivation ++++++++++++++++++++++++."
Several months later I was accepted to AOCS. Yes, Vietnam was hot and a lot of jos were being shot down, so they needed more people. But I wound up in the best service after all. My best friend in college finished AFROTC and wound-up in a missile silo at Malmstrom AFB, Montana, a duty he so hated that he was released early after telling his CO what he thought of him and the Air Force in general.
When I think back to AFROTC and compare that with AOCS the superiority of Navy over Air Force is stark.
