The L6 Wombat, (Weapon Of Magnesium, Battalion, Anti-Tank) was a 120 mm calibre recoilless anti-tank rifle used by the British Army. They were used until anti-tank guided missiles, such as Vigilant and MILAN, took their place. However, WOMBAT was maintained in British Army Anti-Tank Platoons in Berlin to supplement MILAN until the late 1980s, due to the perceived engagement ranges should the Warsaw Pact have ever attacked. The wire guidance of MILAN would also have been problematic in the built up areas of Berlin. It was envisioned that WOMBAT would be used in 'shoot and scoot' attacks mounted on the back of stripped down Land Rover vehicles.

The Wombat replaced the earlier BAT and MOBAT weapons, themselves developments of the wartime designed "Ordnance, RCL, 3.45 in" recoilless rifle, and was in turn replaced by anti-tank guided missiles. The L6 Wombat itself comprised the L12A3 BAT gun, but mounted on a new lightweight carriage.[2] The vertically sliding breech of the BAT and MoBAT was replaced by a lighter horizontally hinged breech. The Wombat was mounted on a small two wheeled carriage, which was removable in order to be moved over obstacles and then locked to the carriage again. The weapon was normally carried in the rear of a specially adapted Land Rover (Portee). The Wombat could also be mounted on the FV432/40 armoured personnel carrier.

The usual round for Wombat was a HESH, which it could fire out to around 1,800 m. The HESH round could defeat 400 mm (16 in) of armour.[3] Other ammunition types include the canister and modified canister rounds. The latter releasing flechettes, or small darts, in a "shotgun" effect. These rounds could be used against infantry in the open. The base of the BAT cartridge case was frangible, the reaction gases venting directly backwards through a single large venturi. This was in contrast to the US recoilless designs, which used a frangible sidewall to the cartridge case and multiple venturi.

During the Cold War era, NATO and British Royal Marine forces used the Swedish made Snow Trac as a carrier for the L6 Wombat in the snow covered mountains of Norway.

Variants[]

  • 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)[4]
A BAT with the shield removed to lighten it (even though it still weighed some 770 kg (0.76 long tons) and a spotting weapon (a Bren light machine gun) added. It could be towed by an Austin Champ or later the Land Rover.
  • L6 WOMBAT (Weapon Of Magnesium BAT)[5]
A new build weapon with lightweight carriage, which meant it was usable by all air Mobile (Infantry Battalions) plus mobile troops such as the Parachute Regiment or 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 2,000 m (2,200 yd). The strike was observed by the No1 who called the fall of shot. The No2 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 as a spotting rifle. (This weapon is often called the .50 cal spotting gun, M8C).
