The M240 is a 7.62 mm general-purpose machine gun featured in both ArmA: Armed Assault, ArmA 2, and ARMA Reforger.
ArmA: Armed Assault[]
« | The M240 is a 7.62mm General Purpose Machine Gun. This very robust and reliable weapon, designed by Fabrique National (FN) of Belgium, is in use by a large number of militaries worldwide. The M240 is used as a coaxial machinegun in a wide array of US armored vehicles, and recently the infantry version replaced the long-serving M60 in US Army service. The M240 is belt-fed and has a selective rate of fire. Library Description[1]

» |

The M240 is used by both U.S. Army and RACS military forces in ArmA: Armed Assault.
Overview[]
The M240 is a gas operated medium machine gun with an open bolt design that is chambered to fire the 7.62×51 mm NATO round.
It feeds from 100-round belts stored in clothed boxes[A1CfgW 5], and can attain a fire rate of up to 800 rounds per minute[A1CfgW 6][Formula 1] with a muzzle velocity of 900 m/s.[A1CfgM 2] It features a (non-functional) integrated bipod fixed below the barrel.
The M240 serves as a heavier counterpart to the 5.56 mm-chambered M249 SAW light machine gun. Unlike the M249 SAW, the M240 has a lower ROF, carries less ammo per belt (100 rounds versus the M249's 200), and is bulkier to wield. However, it compensates by firing the more powerful 7.62 mm NATO cartridge which retains energy better at long range, particularly against targets located beyond 600 metres.
Its main drawback stems from its weight and size, as carrying the M240 will prevent the user from being able to wield a secondary AT/AA launcher[A1CfgW 7] and its long barrel length makes it difficult to wield in close quarters.
Ironsights[]

The M240's ironsights are set to a fixed zeroing of 300 metres.[A1CfgW 8][A1CfgW 9] It is not possible to manually adjust this to a different setting.

ArmA 2[]
« | The M240 is a belt-fed, gas-operated machine gun. This weapon is used extensively by US armed forces infantry, mounted on ground vehicles, boats and aircraft. It is highly prized for its reliability, good rate of fire, impact and durability. The M240 uses 7.62x51 mm ammunition. |
» |

The M240 is used by both the U.S. Marines/U.S. Army forces, and in limited numbers with the Takistani Army in ArmA 2.
Overview[]
Returning from Armed Assault, the M240 once again serves as the mainstay GPMG of U.S. military forces and as an auxiliary weapon on certain Takistani aircraft.
It still loads from 100-round belts stored in cloth boxes[A2CfgW 8] but now has a slightly higher fire rate of up to approximately ~ 846 RPM[A2CfgW 9][Formula 2] (at the cost of its muzzle velocity which has dropped to 834 m/s[A2CfgM 2]). The M240 is additionally available with an alternate variant that has an M145 telescopic sight (designated as the M240 M145) but neither of the M240s have muzzle attachments or side rail accessories fitted.
As before, it is designed to provide suppressive fire at distances of between 800-1,200 metres. The M240 still retains exceptional stopping power against infantry and unarmoured/lightly armoured vehicles thanks to its usage of the 7.62 mm NATO cartridge.
However, just like the Mk 48 Mod 0 and the British Army's L7A2, wielding the M240 prevents the user from being able to carry a backpack. Likewise, the M240's long barrel and heavy weight makes it ungainly to wield in close quarters. In addition, the M240's recoil is very difficult to control when it isn't fired from a prone position. If going prone is not an option, firing in short bursts of 2-4 rounds instead is a must to maintain any semblance of accuracy.
Sights[]


Although the telescopic sight does not have the ability to toggle enhanced vision modes, the user can wear their own night vision goggles while looking through the sight.[A2CfgW 12]

Trivia[]
- In-game U.S. Army machine gunners are erroneously depicted using the same "M240G" ("Golf") variant as the USMC. In reality, the Army at the time of ArmA 2's release exclusively utilised the "M240B" ("Bravo") and not the M240G.[5][6]
- Strangely, Takistani Army UH-1H helicopters are also shown using the M240 despite the fact that their regular ground forces use the Russian-made PKM.
- The M240 incorrectly shares the same model with the L7A2 GPMG. Even though the real-world L7A2 is mechanically similar to the M240 (save for its 10-position gas regulator versus the M240's 3), it is furnished differently and would not be exactly identical to the M240.
- Curiously, the icon for the M240 M145 variant depicts the M240 with an Elcan "SpectreDR" optical sight (which is actually used on the Mk17 EGLM) instead of the in-game "M145 MGO".[7]
- Prior to the latest Steam version patches, it was not possible to adjust the M240's zeroing on the baseline (non-scoped) M240. A visual glitch on the M240 M145 variant would also cause its lenses to remain in place when the feed tray cover was raised during a reload. Both issues were subsequently fixed with the release of the CorePatch updates.[8]
- CorePatch added two hidden derivatives of the M240 that do not prevent the user from wearing a backpack at the same time (Classnames: M240_Small, m240_scoped_EP1_Small)[8], though they are not usable without a custom addon or "adding" them via scripting commands.

The M240 is used exclusively by U.S. military forces in ARMA Reforger.
Overview[]
Reforger's iteration of the M240 now serves exclusively as a vehicle-mounted weapon. It is no longer available in either a static turret or man-portable configuration.

Trivia[]
- Reforger is the first game in the series to not feature the M240 as a standalone, man-portable weapon (ever since the M240's introduction in Armed Assault).
- The M240 was not originally available at Reforger's launch as the LAV-25 (and the M240 itself) did not get added into the game until Update 1.3's release.[9][10]
