I'm well aware. I went to grad school with one, and worked with him a couple years later, a couple thousand miles away, as well.
Generally speaking, though, they aren't going to school to pursue athletic goals; they are getting an advanced technical degree that has value to the USAF, like my friend who used automatic object recognition and GIS to develop tools to detect buildings damaged by hurricanes and earthquakes. He had a much stricter timeline than anyone else and defended his thesis after three semesters. Departed for his next duty station before fall semester graduation.
