Ann Arbor's own military unit.

I'm not going to question the people at the 406th Corps Support Battalion: I probably went to high school with some of them, and I wish them all a healthy and fairly boring 2003 (no long trips abroad, for example). Well actually, I do have one question for them, but I think I'll ask my readers first (the two groups are probably mutually exclusive). The question is: what does the motto "First Without Demand" mean? One year free subscription to this blog for the most creative answer.
