Medical skills draft, anyone?

MSNBC (http://www.msnbc.msn.com/id/8143733/) reports that the military is in need of medical personnel, and they’re approaching paramedics in some pretty gritty areas (in this case, Newark):

A few months ago, Wheat and several of his colleagues here were approached by a Navy recruiter who promised a “tax-free $120,000 bonus” if they agreed to sign on as medical consultants with a Marine Corps unit in Iraq.

“I knew what they were asking, and don’t get me wrong, I was tempted,” says Wheat. “That’s a lot of money, and I really want to help. But I worried that I wouldn’t  be accepted by the Marines, as an outsider, and I won’t kid you – I thought about getting killed or injured. And I decided. Hey, I’m already doing a job that’s dangerous that no one else wants right here. So I said no.”

So, how long until it’s no longer an “offer”?
