Something to do with his eyeballs, I can't remember specifically but I do remember it being something benign and common enough that it should've been noted during MEPS as DQ for his enlistment contract option, instead of just being noted and sent on his way. Chances are they overcommitted with PJ contracts, and probably didn't want somebody sitting around waiting to class up when that time could've been spent gainfully employed. I'm under the impression that series goes in swings with enlistment contracts.
So, he passes through MEPS, completes basic and whatever he had to go through, shows up to PJ school and turn him away at the physical for something with his eyes that was recorded during MEPS but allowed to enlist under his contract option regardless. I think the zoomies call them "GEP" or something, guaranteed enlistment program, some such. In any case, he didn't get into the actual training pipeline to even have a chance to quit. He's still in AFOSI today as a reservist while simultaneously serving as an agent with us, and although he's super happy with his life there's some understandable butthurt over the whole affair.
Something similar also happened to a close friend of mine who enlisted in the Navy with a nuclear power MOS. He got dropped from the training program for some pretty ridiculous stuff. Their school is all on the classified side, so they can't take anything outside the classroom building. He didn't take anything out, but "someone" made an anonymous complaint that he left with a notebook. No effort was made to investigate or recover said notebook which would theoretically have had classified information in it, but rather he got a one-way 5 minute conversation about his lapse in judgement and a boot out the door, find a different job. He stayed for 8 years as an electrician's mate. My brother had gone through the nuke school around the same time frame, and he confirmed that they had just come out of a spell of dropping people for nonsense (on top of Nuke school's already ridiculously high failure rate).
Around 2005 or so, there was a massive purge of junior grade Naval officers because they had over-hired. A couple ended up in the Marines with me....one day at flight school in the Navy, they showed up to class and the instructors said "everyone who has a note card on your desk, please come outside". And just like that....poof, they were cut. I know it wasn't a lie because I had applied for a commission in the Navy around the same time and been told that big Navy had made cuts and all few thousand of us "College Program" applicants had been summarily denied regardless of qualification. We (the Marines) over-hired flight contracts a few years later, but thankfully guys were given the option of serving a tour in the fleet in 3 other MOS's that were short, and then return to flight school after the backlog had subsided. 15 went through IOC and most of them deployed with a reserve battalion that had zero 2Lts, 5 went logistics, and I can't remember the other MOS.
I'm not sure why I feel the need to explain this, anyway. I thought it was self-evident that the military "plays games" like these when such games are advantageous to Uncle Sam. The same thing happens in reverse when a given roster gets too short and all the sudden guys with legitimate medical issues suddenly cannot get a diagnosis from a military doctor in order to pursue a med-sep. I honestly didn't think anyone would be so contrarian to act like this doesn't happen when it's a pretty well known, accepted occurrence. I don't think that @
JRB is talking out of his ass either, given his number of years in.
