Mk II with an Italian Breda 20 mm gun near Tobruk, 8 May 1941.
By early 1941, some Mark IIs had already been officially retrofitted with Italian booty weapons (the Breda 20-mm machine gun). Other vehicles received just what the troops had at hand: French 25-mm Pak, German 37-mm Pak, Italian 47-mm Pak. When one of these vehicles was sent for depot maintenance, the weapons were usually dismantled beforehand. In September, the4th South African Armored Car Regiment even equipped a Marmon-Herrington with a two-pounder cannon from a destroyed British tank, and the vehicle proved to be a great success. Other vehicles were quickly converted so that by February 1942 at least one vehicle per troop had a Pak. Turretless versions such as the Mark IIIA went to the artillery as vehicles for forward observers, but also proved their value as reconnaissance vehicles (due to their lower silhouette). The different variants of the Mark III also included anti-aircraft versions. The Mark III was produced from May 1941 to August 1942.
