Bombardier (aircrew)
(重定向自Bomb Aimer)

A bombardier or bomb aimer was the crew member of a bomber aircraft responsible for the targeting of aerial bombs. "Bomb Aimer" was the preferred term in the military forces of the Commonwealth, while "Bombardier" (from the French word for "bomb thrower" and similar in meaning to "grenadier") was the equivalent position in the United States Armed Forces.
