I don't mean people who left the country or hid or just didn't have their number called. I'm talking medical conditions, having a documented religious objection, or are openly homosexual (I have no idea how other countries feel about gays in the military, but the US is all "don't ask, don't tell" and will kick your Arabic/Farsi-speaking ass out in a heartbeat if you come out).
I will actually answer my own question. My father and his brother got out of the Vietnam War draft in the US because they have colitis. Now, tell me your own stories, please.
