People of any school tend to casually root for the armed forces in athletics. Esp. when they are good and ranked.

Now, we would need Army to be competitive, not come in and win three games a year, losing badly (like UC right now haha). But if they can be bowl eligible-good or at least close (5-6 wins a year) they are a great add.
