The SARC MkIVa has poor survivability, with the 12 mm rounds able to penetrate the sides and 20 mm rounds the front. The crew is very tightly packed, meaning that any shot that hits one crew member it likely to knock out at least two. The SARC being open-topped leaves it highly vulnerable to even low calibre HE and aircraft bullets.

The SARC MkIVa's manoeuvrability and good reverse gear should be used to avoid getting hit and ambush the enemy. Vehicles with 20 mm autocannons and enemy SPAAs are very dangerous for the SARC, as they can easily shred its armour.

The MkIVa does not accelerate quickly. In a city fight or in a sniping match, this is a liability.

This is offset by its very high top speed of 80 km/h. This grants it unmatched speed on flat terrain. Combined with its smaller size, this gives the MkIVa the opportunity to sneak into a hidden location and get flanking shots on unsuspecting enemies.

The MKIVa depends on mobility. Due to the relatively low chance that the crew will survive getting shot, crew replacement is not an immediate priority. Instead, focus first on spare parts and FPE, then better ammunition, then mobility improvements. The strength of the MKIVa is its speed, so upgrades that facilitate that are important. Ignore brakes for last: you shouldn't need to stop better, you need to get to a hiding spot faster.

Armaments

Main armament

40 mm QF 2-pounder cannon

Ammunition37 rounds

Reloadbasic crew → aces

3.6 → 2.8 s

Vertical guidance-5° / 20°

The QF 2-Pounder is a solid weapon for its tier. It can frontally penetrate most vehicles at its BR, but excels in flanking shots. The stock Shot MK. 1 AP shell has poor performance, so take effort to phase this out in favour of the better performing Shot MK IX APCBC.

The slow rotation speed of the turret means that the gun should ideally used in an ambush role on the sides of enemy tanks. The relatively high fire rate also allows for consistent fires on enemy targets.

Be advised that the QF 2-pounder loses accuracy over 500 meters, so it is ill advised to use the gun for this purpose: leave the sniping for the tank destroyers and concentrate on ambushing.

Mount	Capacity (Belt)	Fire rate	Vertical	Horizontal
Coaxial	1,000 (250)	500	N/A	N/A

The M1919A4 is a good machine gun, though it is only useful for knocking out lightly-armoured vehicles like trucks or the occasional half-tracks. The high ammo count per belt means that sustained fire can be used to check bushes and smoke for obscured targets.

In an emergency, it can be used as an anti-aircraft weapon, but the poor damage output and turret rotation speed makes this option less advisable.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Narrow profile; difficult to hit at range
• High top speed on paved surfaces; comparable to fast foes like BT-5
• Quick reload speed
• Fast acceleration; top speed can be reached fairly quickly
• Access to smoke grenades

Cons:

• Low survivability: poor armor can be easily penetrated by anything
• Off-road mobility is lacklustre
• Difficult to control at high speeds
• High center of mass, can tip over when operating on uneven ground
• Below-average gun depression

History

The South African Reconnaissance Car (SARC), known in British service as the Marmon-Herrington, had a remarkably diverse pedigree, as it combined components made in the United States, Canada, and the United Kingdom, put together in South Africa.  The service record of its variants was similarly far-flung, despite its relatively small production numbers, as it saw service in WW2, Cyprus, across Africa, and even (from captured Japanese stock) Indonesia.

This variant, the Mark IV, fitted a 40 mm 2-pdr. gun in an artillery mounting, not the usual tank-style mantlet.  It arrived rather late in WW2, but saw action post-war in Cyprus and with the Arab League.  Earlier versions fought with the 1st King’s Dragoon Guards at the Siege of Tobruk in 1941.
