A guy who refuses to defend his country in a time of war, in favour of becoming a gun for hire (in the point of history where mercs are the most despised) being chosen as an officer candidate? That's optimistic.
"We have a national crisis, and the AFFS need the best officers we can produce; but Jorgensen's daddy paid big bucks, so we'll waste a slot for the mercenary scumbag...".
Even if he does escape the draft, he'll still have black mark in his resume, as being essentially a deserter, even if he's not legally one.
Sorry if I'm rambling; as a veteran I have low tolerance to people who aren't willing to defend their country, even imaginary/fictional ones.
Yeah, in an optimal setting 2 years. But this is a time of war... Imagine if in the middle of the counterattack the British and American soldiers decided the Nazis aren't their problem anymore. Bare in mind that considering military academies, especially one dedicated to training defenders for the Capellan march, have some sort of indoctrination going on (promoting patriotism, honor, duty and what's not), the progeny might insist on "finishing the fight"; considering the disgust felt towards mercenaries at this point, he may decide he doesn't want to be a merc.
