| Notes | The British firm Vickers-Armstrong built a number of light tanks during the inter-war years. In 1936 they designed a light tank that mounted a turret with the capacity to hold three crew members. The chassis was a little short for its width and its armour was only 14mm thick. The 88 hp engine gave it good speed and it handled well enough and mainly because of the Horstmann suspension which was reliable enough. The vehicle was called Mk. IV light tank and it made up the majority of the British army tank strength in 1939. It served in France, Greece, Crete, the Western Desert and Syria. A few were also sent to the Far-East. |
