The Vickers Medium Mark II was a British tank built by Vickers in the Inter-war period. The Medium Mark II, derived from the Vickers Medium Mark I, was developed to replace the last of the Medium Mark Cs still in use. Production and rebuilding ran from 1925 until 1934. The tank was phased out of service from 1939, replaced by the Cruiser Mk I. It featured several improvements over the Vickers Mark I: a higher superstructure with the driver's visor on top of it instead of in front of it; an improved suspension protected by armour skirts; and Rackham clutches, providing a primitive form of mechanical servo-control. Due to a slightly higher weight its rated speed was somewhat slower than that of the Medium Mark I, at compared to . Design The Mark II used the same chassis, suspension and transmission as the Medium Mark I but had a new superstructure. The Mark II was equipped with a 47 mm 3 pdr gun and four machine guns in the turret. The back of the turret had a slope so that the machine gun there could be used against aircraft. There were two Vickers machine guns, one in each side of the hull to the rear. Operational history The Vickers Medium Mark II and its predecessor the Vickers Medium Mark I replaced some of the Mark V heavy tanks. Both tanks equipped the Royal Tank Regiments until they were phased out starting in 1938. The tanks saw their first combat use when two were used against the Mohmands on the Northwest Frontier of British India during the Mohmand campaign of 1935. In November 1939, some Medium Mark IIs were sent to Egypt for experiments being conducted by Major-General Sir Percy Hobart and his Mobile Division (Egypt), but the Vickers Mediums in Egypt were also phased out before Italy declared war in June 1940. The Mediums were used for initial instruction in driver training. During the threat of German invasion of the summer of 1940, some of these outmoded vehicles were reactivated for a short time. No "mobile" Vickers Mediums faced the Italian invasion of Egypt in September 1940, but at least one was dug in as an armoured pillbox in the British defenses at Mersa Matruh at the time of the invasion.
