Army or Air Force coming to town would be HUGE because San Antonio is nicknamed "Military City, USA" as it has an Army base (Fort Sam Houston), two Air Force bases (Randolph and Lackland), and Camp Bullis (a 28,000 acre Army camp near UTSA used for training). We once even have a third Air Force base (Brooks), but it was shut down with military down-sizing. Needless to say, San Antonio is home to MANY retired and active-duty military personnel, so I don't understand why UTSA hasn't yet scheduled one of those academies. Navy would even be a big draw because even though San Antonio is Air Force/Army mainly, there are a lot of retired Navy in the city also because they have access to the military bases as well for shopping, health care, and other things.

Uh by who? If anyone should play a service academy it should be ODU playing Navy. You wouldn't find a ticket in Hampton Roads for that game. There are at least 180k active duty (mainly Navy) personnel or support staff in Hampton Roads alone.
