I'm pretty sure i wouldn't be accepted for health reasons (i've had Hepatitis C and it requires medication and specific diet), so my reply isn't really what you asked for.

Somewhat like Platypi007 stated, i'm in the ministry, and i'm not confident in my ability to kill someone else if required. That said, i've always told myself that if a draft situation presented itself, i would pursue the possibility of chaplaincy. Spiritual guidance is something i would definitely want to be able to offer the the troops defending our country. Of course, that's an officer position, and the training could kick my butt, but i'm up for that challenge. ARGH!
