The Vickers Mk VIB Light Tank was a British WW2 light tank, crew of 3, powered by Meadows 6-cylinder petrol engine, armed with two machine guns.
This is the one at the Tank Museum in Bovington.
The Mk VI Light Tank was the sixth in the line of light tanks built by Vickers-Armstrongs for the British Army during the interwar period. The company had achieved a degree of standardization with their previous five models, and the Mark VI was identical in all but a few respects. The turret, which had been expanded in the Mk V to allow a three-man crew to operate the tank, was further expanded to give room in its rear for a wireless set.
The British Army lost 331 Mark VI light tanks in the Battle of France of 1940.
The Mk VIB was mechanically identical to the Mk VIA but with a few minor differences to make production simpler, including a one-piece armoured louvre over the radiator instead of a two-piece louvre, and a plain circular cupola instead of the faceted type.
The Mk VIB was also used in the North African campaign against the Italians late in 1940 with the 7th Armoured Division.
In A Very British Civil War scenario, you would expect to be using a fair amount of these tanks. When the Battle of France began in May 1940, the majority of the tanks possessed by the British Expeditionary Force were Mark VI variants.
Here are some 15mm Flames of War Light Tank VIs in the Flames of War Miniatures Gallery.
There is also a metal 15mm one of mine, which is badly painted, on my workbench.
There is a Mark VI A on display at the Imperial War Museum Duxford. It was one of 11 sent to Australia in 1941 for training purposes Standard British light tank till 1941.
