The Mark II was a four wheel drive front engined vehicle. It served with both the UDF and British forces. It was initially delivered to UDF armoured car companies in November 1940 while the first units in the Middle East received them in March 1941. A total of 887 Mark II were built. Deliveries ended in May 1941. Armament was initially that of the Mark I. However, the turret and armament were subsequently changed for those serving in the Middle East to a flat faced turret mounting a .55 cal. Boys ATR and a
Bren LMG. There were pintle mountings on the front roof for an additional Bren LMG and a pintle mounting for a Vickers MMG at the rear of the turret. However, it appears that the second Bren LMG was rarely carried.
The Mark III was very similar to the Mark II in appearance. However, it had a shorter wheel base (117 inches instead of 134 inches). Armament was the same as the Mark II on Middle East service. A total of 2,630 were produced with deliveries from May 1941 through August 1942.

a coaxial Bren machine gun and one or two additional machine guns for anti-aircraft defence
