3 round burst
EGLIN AIR FORCE BASE, Fla. -- An Army Ranger explains the "burst" setting on an M-4 to a Cub Scout during the 6th Ranger Training Battalion's 60th Anniversary Open House event, May 7. The event was a chance for the public to learn how Rangers train and operate in extreme situations. The event displays showed dive equipment, weapons, a reptile zoo and zodiac boats. The demonstrations showed off hand-to-hand combat, a parachute jump, a down-pilot scenario and others. (U.S. Air Force photo/Samuel King Jr.)
