Design

Vickers Armstrongs designed and built this tank during the 1920s-30s. This was the first post-World War I tank to go into service with the Royal Tank Corps. Was considered the first "fast tank" in service.

First tank to have the main armament in a revolving turret.¹ The hatches were rather small and could be used for quick exits.¹ The crew entered through small hatches in the side of the hull. Since it used multi-rollers it couldn't be maneuvered at high speed.¹

The armor plates were primarily flat. The engine was located on the left in the front with the driver on the right. The driver had a large hatch he could open to see while on the road. There were 4 men in the turret, with the commander, one to fire the gun, one loaded the gun and handled the MG, and the last to operate the radio.

A fireless cooker with rations for 3 days could be carried in the tank.
