« The SPMG (Special Purpose Machine Gun) is a lightweight medium machine gun, which greatly benefits from modern materials. It is designed to fill the gap between 7.62 mm and .50 machine guns. The SPMG uses.338 Norma Magnum bullet. The effective range of the machine gun is 1500 m, and thanks to advanced technology, it has low recoil.

The SPMG is a .338 general-purpose machine gun used exclusively by NATO forces in ArmA 3. It was added with the release of the Marksmen DLC.

The SPMG is a gas operated, long-stroke piston operated medium machine gun that is chambered to fire the .338 Norma Magnum round.

It feeds from 130-round belts stored in cloth pouches, and can achieve a fire rate of up to 500 rounds per minute, with a muzzle velocity of 807 m/s. The SPMG can be fitted with accessories on its top, side, and underbarrel rails, and can mount attachments onto its muzzle.

The SPMG's recoil can be easily managed, and is relatively light for a full-size MMG while being very accurate at all ranges. In fact, the SPMG's .338 round provides the operator with an MMG that has accuracy on par with marksman rifles like the Cyrus and the MAR-10.

When paired with sniper optics like the AMS, the effective range of the SPMG can essentially extend out to an impressive distance of up to 2,000 metres.

Notably, the SPMG's .338 round is also highly effective at penetrating through thick walls. Steel and corrugated iron alike offer no resistance, and even moderately-thick stone/brick walls are unable to stop the SPMG from punching through. It can clear drivers and occupants out of MRAPs without damaging the vehicle, other than potentially causing damage to its tyres and turret.

However, the SPMG's primary drawback is its somewhat underwhelming rate of fire. Unlike its CSAT counterpart, the SPMG is unable to lay down fire as quickly due to its pitiful cyclic fire rate of just 500 RPM. The Navid on the other hand, is capable of reaching anywhere from 705 up to a maximum of 1,500 RPM (on burst mode).

The SPMG can only be fed with 130-round cloth pouches. It has a "mass" value of 60 units:

  • The SPMG is based on the real-life "Lightweight Medium Machine Gun" designed by the General Dynamics Corporation.
    • The real LWMMG is a prototype medium machine gun that is being designed to replace its heavier predecessor, the "M240" GPMG that is currently being used by all branches of the U.S. military.
  • Armed variants of the Prowler LSV are fitted with a forward-facing SPMG that can be used by the commander. It is also only used by both models of the Rhino MGS as a coaxial MG, though oddly enough, neither the Slammer family of MBTs nor the Marshall IFV use it as a coaxial weapon.
