The use of the Medium Tank Mk.I revealed both positive and negative sides of the vehicle. The suspension, for instance, revealed one major drawback. It migrated to the tank from a tractor which would be unlikely to spend a lot of time on the front lines. On a tank, the protruding suspension elements became a tempting target for enemy infantry, which could damage them with any weapon, even a non-anti-tank one. There were also complaints about the placement of the driver in a location that created large dead zones. Even the 3-pounder (47 mm) gun no longer satisfied the military. Here the issue was more one of future-proofing, as the gun was enough to fight the vast majority of tanks at the time.
Work on a deep modernization of the Light Tank Mk.I began in 1923. and a year later, the contract for 58 vehicles indexed Light Tank Mk.II was awarded. That name didn't last long, and the tank entered history under the name Medium Tank Mk.II. As with the Medium Tank Mk.I, the order was split up between two manufacturers. Tanks with WD numbers from T.61 to T.95 were produced by ROF Woolwich. Vickers Limited earned a smaller share of the contract: tanks with WD numbers T.96-T118.
