The driver's compartment and the fighting compartments were not separated. As well as the turret armament, which consisted of an Ordnance QF 2 pounder gun and a coaxial Vickers machine gun, there were two small turrets either side of the driver's compartment, each with a Vickers machine-gun. Both of these smaller turrets were permanently manned, which gave the tank a total crew of six (commander, gunner, loader, driver and two machine-gunners).
