Things might have changed since the 1980s (I bet not) but I know recruiters have one of the toughest jobs in the Army. Not the most dangerous, but a demanding grind. I happend along two guys discussing it at one point when I was in the reserves and they were talking about guys intentionally going out of their way to flunk the piss test to get out of it.
All the stress of a salesman, but with none of the financial benefits that go with it.
