A4, Light Tank Mark II

Light Tank Mark II was introduced into service in 1930 as a direct development of Light Tank Mark IA. It was one of the first vehicles to have Cemented Tank Armour, a type of face-hardened armour which resulted in significant weight savings. This armour was used in all light tanks henceforth, up to Mk VI. The leaf suspension of the Light Tank Mark I was replaced with Horstmann suspension with horizontally mounted springs. Light Tank Mark II was still in use as a training vehicle as late as 1940.

Summary of Principal Light Tank Mk II Variants

Two fuel tanks. Built by Royal Ordnance Factory.

No 1 Mk II turret has air louvres on each side at the top. The sliding roof hatch of the No 1 Mk I was replaced with a more secure arrangement of a folding hatch with two doors.

Light Tank Mk IIB

One large capacity fuel tank. Built by Vickers.

Turret as Mk IIA

Light Tank Mk II Indian Pattern Square non-rotating cupola on louvred turret. Sources suggest that these vehicles were not refitted with Rolls Royce engines.

Originally these vehicles were manufactured with a Meadows engine, but most were refitted with a Rolls Royce engine.

Turrets later upgraded to Mk I* and Mk II* both with louvres with anti-bullet splash baffles fitted.

The suspension was also upgraded on most vehicles to a dual spring system.
