|«|| The M2A4 Slammer UP is the urban purpose variant of the M2A1 Slammer. Compared to the base version, it features heavier armor with reinforced rear of the tank and a remote-controlled turret. This weight increase had to be compensated somewhere - M2A4 is fitted with a less powerful 105mm cannon compared to the 120mm of the base Slammer.|
The Urban Purpose variant of the Slammer is armed with a smoothbore 105mm cannon that can fire a mixture of armour-piercing and high-explosive shells. In addition, it has a coaxially mounted 6.5mm light machine gun, and a 12.7mm heavy machine gun fitted externally to the top of the turret that 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 40 rounds of armor-piercing fin-stabilized discarding sabot (APFSDS-T) and 20 high-explosive anti-tank multi-purpose (HEAT-MP-T) shells for the main gun. The coaxial machine gun comes loaded with one linked belt of 2,000 rounds of 6.5mm ammunition, and a spare belt of another 2,000 rounds. Lastly, the externally mounted heavy machine gun comes pre-loaded with a 500 round belt box of 12.7mm ammunition, with another box of 500 rounds left in reserve.
Just like its baseline variant, the Slammer UP is the slowest and least manoeuvrable of the three MBT designs. This lack of mobility however, is compensated by having additional Explosive Reactive Armour (ERA) panels installed on the Slammer UP's armour skirts, front armour, and on the turret itself. Combined together 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.
Unlike standard M2A1s, the Slammer UP uses a smaller calibre main gun instead (105mm vs. 120mm) but does not lack a turret-mounted machine gun. 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 passenger compartment.
The Slammer UP has a seating capacity of nine personnel including the crew. The crew includes the driver, gunner and commander.
- 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.
- 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.
