Army Tank Battalion

The light and medium tanks of the British Army were organised into Army Tank Battalions.

1940 was at a time when the Vickers .303-inch Mk VI, VI* and VII and .5-inch Mk V were being replaced by the Besa machine gun in both the medium  and heavy role – 7.92mm and 15mm replaced .303-inch and .5-inch respectively.

These battalions were organised from units of the Royal Tank Regiment and tank-equipped cavalry regiments.
