. * Mark IIA CS: some Mark IIAs were later rebuilt as close support vehicles, their main armament replaced by a 15-pounder 3.7 inches (94 mm) howitzer, mainly intended to give smoke cover, though some HE shells were also carried.[3] Each company headquarters was equipped with two of these vehicles.[3] The weight was increased to 14 tons.

A Mark IIA CS (close support) DECISION
with his 15 pdr. 3.7 inches (94 mm) howitzer in high elevation.
4th Battalion, Royal Tank Corps. 
* Mark C: was never ordered by the British army, and was built exclusively for export. The main gun was a 57 mm 6-pouder gun, like the ones used on the WWI tanks. There was also a machine gun in the turret, but it was located in the rear, inside the turret bustle. In order to compensate for the lack of a coaxial machine gun, the designers installed another machine gun in the front of the hull, in addition to the two on the sides of the hull. Vickers engineers decided to place a door in the right part of the front, in a truly a strange position. A prototype of the Medium Tank Mk.C was finished in 1926. The British army put the tank through trials and quickly rejected it. On the other hand, a foreign customer was found quickly, with the Japanese bought the tank in 1927, and it became the progenitor of the Type 89 medium tank. Curiously enough, the Japanese kept the door in the front, the hull gun, and the curious arrangement of the armament in the turret. 
. * Mark D: the Vickers Mk. D was a one-off design built for the Irish Free State and delivered in 1929. Only one was built. It was almost identical (even mechanically) to the Mk.C, with the difference being the presence of a cupola for the Commander on top of the turret. They had a water cooled, rear mounted, 6-cylinder Sunbeam Amazon petrol engine, developing 170 bhp (130 kW) at 2100 rpm. A 6 pdr gun was fitted and as many as four Vickers .303 (7.7 mm) machine guns. This tank was scrapped in 1940.
The base model with 47MM or C/D with 57MM could make a fun derpy BR2 tank. Having several machine guns but a profile that screams barn door. The CS is more fun with a 90MM howitzer that can kill BR1 2 tanks and infantry. Lightly armored but good for low br and big but not big as a certain Russian giant.
