A U.S. Air Force F-16CM Fighting Falcon taxis along the runway to join sister service aircraft during basic fighter maneuver (BFM) training at Shaw Air Force Base, S.C., Dec. 1, 2017. BFM training placed pilots against “foreign” aircraft as a way to see how certain aircraft react to one-on-one battles against different airframes.
