The Marmon-Herrington Mk.III: Just Barely Enough...

The Marmon-Herrington Mk.III: Just Barely Enough…


Hello fellow Warthunderers! Today’s suggestion is the Marmon-Herrington Mk.III Armored Car, a vehicle that just barely fits the requirements to be added into the game, serving in the British/South African Army across Africa, and seeing action in WWII.

  • Additional: 1x .303 (7.62 mm) Vickers Machine Gun (Pintle-Mounted)

Usage in Battles

The Mk.III would be an interesting low-rank or starter vehicle, requiring a fair bit of skill to use effectively, seeing as its primary armament can just barely pen armor, it will heavily rely on flanking maneuvers and ambushing opponents, taking advantage of its fantastic speeds to out-pace its opponents.


  • Fantastic Manueverability

  • Rapid reload rate for follow-up shots

  • Smaller profile makes it harder to hit


  • Extremely poor survivability due to armour

  • Often Ineffective AT-Gun

  • Low weight mean obstacles can stop the vehicle


The Marmon-Herrington Mk.III was designed as early as 1940, being the most produced variant of the Marmon-Herrington family. It was essentially an enhanced version of the Mk.II, with a slightly shortened wheelbase for more agility, modified sloped armor, though unchanged thickness, and fitted with a more powerful Ford engine.

The new turret was bigger than the original Mk.II, being octagonal with a rear turret basket, having a two piece front for Boys AT rifle protruding from one and a MG port from the other. The turret had two small side slits and a two-piece hatch. The armored body was of welded construction and the tires were self-sealing.

Production was assumed in the same way like the previous models, with the four-wheel drive train and transmission from Marmon-Herrington in the USA, the chassis and engine supplied by Ford Canada, and armament supplied by the British. Assembly was then performed locally by the Dorman Long Structural Steel Company for the armored body and the Ford Motor Company of South Africa for the final assembly, fittings and its delivery. Production started in May 1941, and halted in August 1942. By then, 1780 Mk.III MFFs had been delivered, and several variants/modifications produced. The production was halted in the summer of 1942 because the Mk. III had shown limitations both in protection and armament.

The Marmon-Herrington Mk.III had better manueverability than its predecessor, but had the same protection issues. The armament was light and the Boys AT rifle could not be compared to AT guns like the 2-pounder. They were still assigned to reconnaissance units and saw skirmishes with anything they encountered, sometimes well behind enemy lines, due to their already long range being supplemented by extra spare parts and fuel cans. While it may have been considered sub-par, a handful of historical documents and photographs show that many Mk. III vehicles were rearmed with captured guns like the German Flak 38 20 mm (0.79 in) or Breda 20 mm (0.79 in) guns, inside a modified turret.

British West African forces operated 60 Mk.IIIs, the Free French had 10 Mk.IIIs in Central Africa, and outside Africa, 255 were used in India, and 175 in Malaya, Mozambique and Rhodesia. By 1943 these vehicles were gradually being phased out and were kept for training or rear-guard patrols in Africa. For the Royal Dutch Indies army, or KNIL, 49 were purchased in 1941 and arrived just before the Japanese landed on Java. They were in poor condition and lacked any armament. After some time the KNIL managed to have 27 of the 49 operational, in those were assigned into two independent recon platoons, the 1st and 2nd based at Bandoeng. The Greeks also operated a small number of Mk.IIIs just prior to the German invasion in May 1941.

Hard pass on this one, there are simply better boys platforms, if your going to suggest the harringtons, the exotics are simply more interesting and would preform better

+1 as a TT Reserve Scout, though with things the way they are you don’t find Scout vehicles at BR 1.0.

I can’t see any place for it beyond Reserve and with the light armament, Scouting would give it a purpose.

Yea the idea is that it’s essentially a British Csaba, except somehow worse lol

Not really comparable tbh, the boys is like 13mm to the solothurn’s 20.5mm. something like the besa 15mm is more comparable, seeing as the boys at has a rof of like 10 rounds a min due to recoil recovery

The Boys .55 could have access to APCR, which has a penetration of around 35-40mm+ according to gaijin’s pen calculator. Since the filler in the Csaba’s round causes it to explode in a puny fashion post-pen, it tends to do less damage than if it would have stayed intact, which an APCR round does. So this means that it could be equal or better than that vehicle, at least.

Also, correct me if I’m wrong, but isn’t the rifle fastened in the vehicle of the Marmon-Herrington? That could mean a very low recovery rate between shots and could speed up the firing rate.

I don’t have exact figures of the APCR projectile but it seems to have a ~6.3mm tungsten core at 920 grains and a muzzle velocity of 944 m/s. I haven’t found the complete weight of the projectile yet, so if anyone finds it please share :). Source

I have a few rounds in my collection, but i have not yet unboxed my shells, so i could potentially weigh one in the future :)

OMG, please do! That would finally provide good performance data. And you’d plug an existing information gap on the internet :)

Also iirc they are not apcr, they are just a regualr bullet with a cement core, its in one of my many boxes of things i have hoovered up over the years

Shhh, I think we can get more pen out of it if we treat it as an APCR round ;)

not really, the concrete would give it more as it increases its weight. the idea was to in increase density, higher density = higher pen according to the ingame calculator

found it

now i need to weight it at some point


dew it!
