A tail gunner or rear gunner is a crewman on a military aircraft who functions as a gunner defending against enemy fighter attacks from the rear, or "tail", of the plane. The tail gunner operates a flexible machine gun emplacement on either the top or tail end of the aircraft with a generally unobstructed view toward the rear of the aircraft. While the term tail gunner is usually associated with a crewman inside a gun turret, tail gun armaments may also be operated by remote control from another part of the aircraft.
