[2] the Wombat was also issued to some TA battalions such as 5th Battalion, The Royal Anglian Regiment BAT was developed from the wartime Ordnance, RCL, 3.45 in,[3] replacing it and the Ordnance QF 17-pounder to become the standard anti-tank weapon of the Army in the post-World War II era.

WOMBAT remained in anti-tank platoons in Berlin to supplement MILAN until the late 1980s, due to the expected engagement ranges should the Warsaw Pact have ever attacked.

The base of the BAT cartridge case was frangible, the reaction gases venting directly backwards through a single large 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.

Wombats were among the anti-tank weapons taken by the Parachute Regiment to the Falklands War in 1982, but they were not off-loaded from the transport ships.
