I know you asked him but...
I think you have a 4 year obligation to serve. After 4 years you can decide to opt out and get an honorable discharge or sign another 4 year contract. Of course, you can fuck up and get yourself kicked out on purpose, but if you go that route, you might as well have a felony on your record, Dishonorable discharges are hard to shake, at least that's what they make you believe. Or you could go AWAL like a real man, but that is an actual felony.
lmao desertion. I heard of a story of a marine who went UA during vietnam and turned himself in like 40 years laterr
