Bombardier is a rank used in artillery units in the armies of Commonwealth countries instead of Corporal. Lance-Bombardier is used instead of Lance-Corporal.

A bombardier, in the United States Army Air Forces and United States Air Force, or a bomb aimer, in the Royal Air Force and other Commonwealth air forces, was the crew member of a bomber responsible for assisting the navigator in guiding the plane to a bombing target and releasing the aircraft's bomb load. In the modern age, the position has fallen into disuse due to a rise of computer technology and smart bombs.
