120mm L2 BAT

Also known as
  • L2 BAT
  • L1 BAT
  • BAT recoilless rifle

  • 120mm BAT
  • L4 MOBAT

  • L7 CONBAT

The 120mm L2 BAT was the British Battalion Anti-Tank recoilless rifle, a heavy towed 120 mm HESH-firing weapon introduced in 1953 as a postwar infantry anti-armor system. Its same-family L4 MOBAT, L7 CONBAT, and L6 WOMBAT variants traded the shielded L2 carriage for lighter or better-sighted configurations; Australian War Memorial records place an L4 MOBAT/BAT gun with Commonwealth forces in Malacca during the Indonesian Confrontation.

BAT Family Design

The L2 BAT was heavy for an infantry anti-tank weapon, so the family evolved through lighter and better-sighted versions while retaining the 120 mm recoilless anti-armor role.

Original BAT

The L2 used a two-wheel carriage, gun shield, optical sight, and 120 mm breech-loaded recoilless barrel.

MOBAT

The L4 MOBAT removed the BAT gun shield, used a Bren spotting rifle, and reduced the system to about 766 kg for light-vehicle towing.

WOMBAT

The L6 WOMBAT put an L12A3 BAT gun on a lightweight carriage and added .50 caliber spotting-rifle support for longer practical engagement.

Variants

The BAT family used the same British 120 mm recoilless anti-tank concept across shielded, lightened, and spotting-rifle-equipped versions.

L4 MOBATLighter mobile BAT variant

WeaponSystems.net identifies the L4 MOBAT as the Mobile Battalion Anti-Tank version with the shield removed, 7.62 mm Bren spotting rifle, 766 kg weight, and 825 m effective range; the Australian War Memorial documents one in Malacca during the Indonesian Confrontation.

L6 WOMBATLightweight airborne and mobile variant

Airborne Assault Museum identifies the L6 WOMBAT as an L12A3 120 mm BAT gun on a lightweight carriage, towable by or mountable on a Land Rover and used by airborne units.

L7 CONBATConverted BAT/MOBAT with spotting rifle

Specialist summaries identify CONBAT as a BAT-family conversion with a spotting-rifle attachment, bridging the earlier BAT/MOBAT guns and the later WOMBAT configuration.

  5. WOMBAT photographed beside MILAN

    A National Army Museum photograph of the Duke of Edinburgh's Royal Regiment shows a Wombat anti-tank recoilless rifle with a MILAN missile, illustrating the overlap between the older recoilless rifle and the missile that replaced it.

  6. WOMBAT embarked but not fought in the Falklands

    Airborne Assault Museum records WOMBATs as embarked for the Falklands but not deployed in combat, a useful boundary for excluding a Falklands conflict-use row.

L6 WOMBAT Service Context

The L6 WOMBAT was the late lightweight BAT-family service weapon. Museum records connect it to airborne trials, British airborne service, Malaysia-based training, and the transition from recoilless anti-tank rifles to guided missiles.

Air transportable role

Airborne Assault Museum describes the L6 as a lightweight-carriage 120 mm recoilless rifle that could be towed by or mounted on a Land Rover and was used by airborne units.

Malaysia training

Australian War Memorial footage metadata places 8 RAR anti-tank troops training on the 120 mm Wombat at Terendak and Asahan in February 1969, noting that the British Army used the weapon in Malaysia.

Missile replacement

National Army Museum and Airborne Assault Museum records frame WOMBAT as a legacy recoilless anti-tank rifle that overlapped with, then gave way to, guided anti-tank missiles such as MILAN.

A 1964 joint-services ammunition-marking handbook identifies the service store as 120 mm B.A.T. H.E.S.H. L19A3, while specialist sources use the L2 HESH label for the BAT-family round. Australian War Memorial collection data documents BAT HESH ammunition tubes with an L4 MOBAT in Malacca during the Indonesian Confrontation, giving the round a direct source-backed conflict context without implying that the specific photographed rounds were fired.

British units received the gun in 1941, Australian War Memorial and Royal Artillery sources place its first operational service in May 1942, and the type served with British and Commonwealth forces in North Africa, Italy, and northwest Europe before later South African G2 use in the Border War.
