A13 Mk II Cruiser Mk IV
The A13 Mk II Cruiser Mk IV was in essence an uparmoured version of the A13 Cruiser Mk III. This increase was mainly added to the frontal armour of the tank; despite the increase in weight due to the extra armour mobility was not affected due to the high power-to-weight ratio of the basic design.
The most distinctive feature of the A13 Mk II Cruiser Mk IV is the V-section armour on the turret sides. This “spaced armour” was later used by the German tank designers and made it easy to distinguish between an A13 Mk II Cruiser Mk IV and an A13 Cruiser Mk III.
