The small computer lab set aside for military students on the Gainesville campus of the University of North Georgia is empty except for two women chatting in the back. Sgt. Didi Ucherkemur runs a hand through her multihued hair while Sgt. Tonya Butler-Collins fills her in on the details of an upcoming engagement. Butler-Collins, an assistant professor of health, physical education and recreation at UNG, also is a self-deemed “deadly flutist.”
