• L2 BAT, Battalion Anti Tank :The original towed gun complete with a heavy armoured shield and wheeled mount. Accepted for service in 1953. • L4 MoBAT (Mobile BAT) :A BAT with the shield removed to lighten it (even though it still weighed some and a spotting weapon (a
Bren light machine gun) added. It could be towed by an
Austin Champ or, later, a Land Rover. • L6 WOMBAT :A new build weapon with a lightweight carriage, which meant that it was usable by all air Mobile (Infantry Battalions) plus mobile troops, such as the
Parachute Regiment and
Royal Marine Commandos. It was also fitted to vehicles, such as the
FV432 or a 3/4 ton portee
Land Rover. When fitted with an M8C .50 cal
spotting rifle, which fired a zirconium-tipped spotter tracer round visible past 2,000 yards, it could engage targets out to . The strike was observed by the No. 1, who called the fall of shot. The No. 2 maintained the spotting rifle and observed the back blast area. The WOMBAT entered service in 1964, rapidly replacing earlier versions in service with the regular army; but it never fully replaced MOBAT and CONBAT with infantry units of the
Territorial Army. • L7 CONBAT ("Converted BAT") :A conversion of the L4 MoBAT or L2 BAT utilizing a L40A1 12.7 mm
spotting rifle. (The American designation was the .50-cal M8C spotting rifle. It used a shorter cartridge than the .50-cal machine gun.) The tracer rounds matched trajectory with the CONBAT to 350.
