A mine flail is a vehicle-mounted device that makes a safe path through a minefield by deliberately detonating land mines in front of the vehicle that carries it. They were first used by the British during World War II.

The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant.

The armor plate on the M3 was too heavy for welding and had to be riveted in position.
