« The M2A4 Slammer UP is the urban purpose variant of the M2A1 Slammer. Compared to the basic version, it features heavier armor with reinforced rear of the tank and a remote-controlled turret fitted with 12.7 mm heavy machine gun.
Field Manual


Deployed specifically for use in supporting combat personnel operating in urban environments, the Urban Purpose variant of the Slammer is armed with a smoothbore 120 mm cannon that can fire a mixture of armour-piercing and anti-personnel shells.

It has a coaxially mounted 7.62 mm medium machine gun and a 12.7 mm heavy machine gun fitted externally to the top of the turret, both of which can be used against both soft targets and low-flying aircraft in lieu of the main gun.

The standard loadout of the Slammer UP gives it 24 rounds of armor-piercing fin-stabilized discarding sabot (APFSDS-T), 12 high-explosive (HE-T), and 12 high-explosive anti-tank multi-purpose (HEAT-MP-T) shells for the main gun.

The coaxial MMG is pre-loaded with a single 200-round belt, and has a further 19 belts in reserve. The externally mounted 12.7 mm HMG on the other hand, feeds from a 200-round belt box and has another three boxes worth to spare.

Just like its baseline variant, the Slammer UP is the slowest and least manoeuvrable of the four main MBT designs (though again the Slammer is still quite mobile compared to older tanks).

This lack of mobility however, is compensated by the Slammer UP having additional Explosive Reactive Armour (ERA) panels that are installed on the armour skirts, frontal armour, and the turret front and sides.

Combined with the Slammer's already high level of protection, this makes the Slammer UP even tougher to take down compared to standard M2A1s, and greatly enhances its survivability against anti-tank missiles and rockets.

Altogether, this takes the Slammer's already excellent level of base protection to a whole new level. With a skilled crew, a toolkit, and a good commander who knows when to fight and when to retreat, it becomes an extremely difficult threat to take out even with heavy ATGMs like the 9M135.

Unlike standard M2A1s, the Slammer UP does not lack a turret-mounted machine gun, which means that the commander can engage their own targets separately from the gunner, and potentially use it against low-flying aircraft as well. And as with the baseline variant, the Slammer UP also has the ability to carry half a squad's worth of infantry in its rear storage compartment.

Crew Capacity
The Slammer UP has a seating capacity of nine personnel including the crew. The crew includes the driver, gunner and commander, as well as up to six passengers.


  • Sand: Standard pattern-less dark tan paint scheme used by all NATO ground vehicles and certain aircraft. This can be universally employed in all types of terrain, but is more suited to arid and forested environments. Any camo nets applied on the Slammer's hull or turret will use a three-tone desert camouflage pattern scheme.
  • Olive: Tropical olive green paint scheme. Only useful for jungle or woodland environments. Camo nets attached to the Slammer use a three-tone woodland camouflage pattern when this scheme is used.


  • Camo Net (Hull): Drapes the entire hull with camouflage netting. Partially conceals covered sections from thermal sensors.
  • Camo Net (Turret): Identical to the Hull camouflage netting, but for the turret instead. The barrel and most of the turret is concealed, though certain components such as the pintle mount and commander optics are not covered.


  • Like its base counterpart, the M2A4 is based off the real-world "Merkava Mark IV" MBT.
  • The Slammer UP uses the same bolt-on composite armour skirts as the M2A1 but has ERA (Explosive Reactive Armour) panels installed as well which, prior to the release of the Tanks DLC, were purely cosmetic.
  • Screenshots shown during ArmA 3's development indicated that the M2A4 was originally intended to be included on release of the final version of ArmA 3.
    • However, the M2A4 would not become available for use until it was added as part of Game Update 1.12 for the first anniversary of the Alpha's release.
  • The main gun was refactored to a 120 mm cannon after the release of Game Update 1.82. Prior to this, the Slammer UP was armed with a smaller 105 mm cannon instead.
