This is a British-designed 120mm rifled tank gun, originally fitted to the Chieftain and later the Challenger 1. Like the later L30 of the Challenger 2 (presented in Driver's Guide: Czech Your Engine), it uses separate propellant and projectiles rather than unitary cartridges.

As with other tank guns, reloading the L11A5 requires one operational action on the part of the loader, gunner, or commander. The loader can declare this action before the gunner fires, completing the action after the weapon cycles.
