I definitely would serve if drafted, no question about it. Heck, right now, if I have a hard time getting a job after college, I'd probably try to enlist in Officer Candidate School for the Navy or Air Force. I've never hard any ethical qualms with respect to military service.
I'd probably try to volunteer as an officer. Actually one of the guys in my accounting classes was in the military and became a logistics officer. Apparently they like having CPA's in those roles. It seems like a relatively safe way to spend a war.
Doesn't that basically mean the army discriminates by socio-economic status? People wealthy enough to afford the right kind of studies get the safe desk jobs, while those who can't have to face death and injury daily.
I don't think its that simple. It's not like the safe jobs don't have grunts in them (who do you think is loading the trucks in the logistics department?) and the guys getting shot at have junior officers getting shot at too.
Yes accountants and engineers and so on get off easy, but you have to weigh that against the guy with a BA who's virtually guaranteed to wind up being an on the ground officer.
