U.S. Air Force Senior Airman Sean Whitaker, a Spangdahlem mixed martial arts member from Pittsburgh, fights for position over his opponent during his match at an MMA tournament in Pruem, Germany, March 8, 2014. Fighters have approximately six weeks notice before fighting in an event; Whitaker had only 12 days to prepare due to last-minute changes in the lineup.
