I dont know how the military works, contract wise, so i apologise if this question is stupid but:
If the troops come back from afghanistan, would they immediately be unemployed? I'd imagine they would just be based at a national military base (or in some other country)?
That's a good question. I would assume that most of them would take on a job as a police officer, or something related to that. Most of the soldiers that come home end up homeless anyways.
