Perhaps most famous for the chase scene in 1989’s Indiana Jones and the Last Crusade, the tough, boxer-engined BMW motorcycle played a part in the German Army's World War II successes. With a sidecar-mounted machine gun, it was fast and agile, providing roving suppression fire.
Later models had the dreaded MG-42, an air-cooled machine gun capable of a high rate of fire. Over 16,000 such BMW motorcycles were built over the course of the war, many of them armed in this fashion; they were present on all fronts, from the frozen steppes in the east to high-speed desert combat with the Afrika corps.
