The Marmon-Herrington MkIV model is here

In March 1943 the Mk IV versionwas produced. This was the last version produced during the war. This monocoque vehicle presented a real improvement over previous designs with a completely different profile with a rear engine and a larger turret armed with a 2 pounder gun (40 mm/1.575 in) and a 7.62 mm Browning machine gun, this armament putting it more on par with enemy vehicles of the time. The armor was quite light, 12 mm in front and 6 mm on the sides. Produced in more than 2000 copies, it was the version that remained in service the longest, until the 1990s in some countries. The 2 pounder gun used an artillery mount because the turret was not suitable for mounting with a classic tank mantlet and was shoulder elevated. Two sand ramps were attached to the chassis and formed an open storage. The crew consisted of three members: a pilot in the front with excellent peripheral vision due to the three flaps (one in the front and two on the sides), and two members in the turret (commander and gunner) with a relatively large turret. The three-faceted turret was open-topped, with a semicircular opening specifically suited for the African theatre of operations. There were also two side slits in the front sides of the turret and two mushroom-type ventilation caps. A second machine-gun could be installed on an AA mount, located on the right side of the front roof section. A storage basket was installed at the rear, and the turret could receive smoke projectors. There was a fixed searchlight on the right side of the turret. A Wireless N°19 Radio was installed at the rear, with two whip antennas. Depending on the models small differences appeared, for example the roof of the turret could be completely open, half covered from the rear or completely covered, small side protections could be added on the sides of the gun, differences also appeared on the tool location and of course on-board radio models. What is curious was that the name Marmon Herrington remained even though this model no longer had any components from this firm.

 

There were two versions of the MkIV differing in the chassis elements:

 

The classic MkIV:

monohull on which were grafted chassis elements from the firm Marmon Herrington. It was built 936 vehicles, 626 of which were armed only with machine guns.

 

The MkIVF:

In 1943, the British army ordered 1200 copies. Unfortunately Marmmon-Herrington could not supply enough 4X4 conversion kits. The army thus turned to another solution by using elements of 4X4 ​​trucks Canada Ford F60L or CMP (Canadian Military Pattern) Ford 3 t truck. Modifications also included a coaxial 0.3 in (7.62 mm) machine- gun. The models produced from these elements received the denomination of MkIVF. It was built in 1180 copies until 1944. Considering that from 1943 the US supplied vast amounts of such vehicles, the Marmon-Herrington MkIV armoured Cars were given, apart from the South African units, to the British, Indian, New Zealand, Greek, Free French, Polish, Dutch and Belgian forces.

 

After World War II, a few were given to the Transjordanians and saw combat with the Arab Legion in the 1948 Arab-Israeli War. Many had their turret lengthened at the front in order to house a 6 pounder (57 mm/2.24 in) gun. Some even had the turret completely removed, making room for the installation of a Vickers 2.95″ (75 mm) mountain howitzer in its place. Israel obtained Mk.IVs from unofficial sources, while the Syrians directly purchased some IVFs. Some Mk.IVFs saw combat as late as July–August 1974 (Turkish invasion of Cyprus), with the Cypriot National Guard. The Greek army retained some Mark IVs in the Aegean Islands well into the 1990s.
