In 2003, shortly after arriving in Iraq, an anti-tank mine blew off Army Maj. David Rozelle's right foot and part of his leg below the knee. Today, after three combat tours in Iraq -- two of which came after his injury -- Rozelle is the new commanding officer of the University of Å·ÃÀ¿Ú±¬ÊÓƵ Boulder's Army ROTC program.
