The British Mark V tank was an upgraded version of the Mark IV tank, deployed in 1918. It was used in action on several occasions, such as the closing months of World War I and the allied intervention in the Russian Civil War on the White Russian side. The tank was also used by the Red Army. It deployed a power of 150 Boiler horsepower, was able to embark up to 8 crew members, and carried two 6-pounder cannons and ten machine guns. Its armor was 16mm wide in the front, 12mm on the sides, and 8mm on the roof and belly. It could not go faster than men could run, though.
