Tank Battalions and other tank establishments

The Inter-War Period

In 1927, the organisation of a Tank Battalion of the Royal Tank Corps was a headquarters, radio telephony section and three companies.

The Second World War

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.

Another tank unit that existed in 1941, as part of the UK’s home defence, was the Light Tank Troop for Aerodrome Defence. This was three light tanks and their crews detached from their parent unit and located to prevent landings and attacks on the aerodromes and airfields. The light tanks would have been those available for service at the time so may have included those armed with the Vickers machine gun.
