The MG3 is a 7.62 mm general-purpose machine gun used by West German military forces in ArmA 3. It was added with the release of the Global Mobilization - Cold War Germany Creator DLC.

Overview[]

This section is a stub. You can help Armed Assault Wiki by expanding it.

The MG3 is a short-recoil operated and striker-fired general-purpose machine gun with a roller-locked bolt carrier, firing from a closed bolt. It is chambered to fire the 7.62×51 mm DM21 cartridge.

It feeds exclusively from 120-round belts stored in ammoboxes, and can attain a fire rate of up to 1,200 rounds per minute[CfgWp 6][Formula 1] with a muzzle velocity of 820 m/s.[CfgWp 7][Formula 2][note 1]

The MG3 cannot be fitted with optical sights, suppressors, or flashlights/laser sights, but it does feature the ability to deploy its integral folding bipod.[CfgWp 8] Its ironsights can be manually adjusted up to a maximum zeroing of 1,200 metres.[CfgWp 9] A dedicated AA sight is also available if the MG3 is being employed for anti-air purposes.[CfgWp 10]

Variants[]

LMG M/62[]

The LMG M/62 7.62 mm medium machine gun.

The LMG M/62 is the Danish military's designation for the MG3.

Aside from minor aesthetic differences with its furniture, the LMG M/62 is statistically identical to its West German counterpart and has no functional changes from stock MG3s.

MG3 - Anti Air Tripod[]

The MG3 - Anti Air Tripod is a static defence version of the MG3. It is mounted onto a raised tripod and has completely identical performance to its man-portable counterpart.

By default, the static MG3 is pre-loaded with one 120-round belt box and has a further three in reserve (for a combined total of 480 rounds).[CfgVh 2] Reloading the MG3 with a fresh belt will take up to 8 seconds to complete.[CfgWp 19]

Its tripod can be fully rotated in all directions horizontally[CfgVh 3][CfgVh 4] but has an elevation limit of 45 degrees[CfgVh 5] and a depression of 13 degrees.[CfgVh 4]

Upon disassembly, the turret will be broken down into two components: the tripod itself, and the MG3 weapon and its belt boxes.[CfgVh 6][SCR 1] Reassembling the turret does not require the original MG3. A turret can be erected using either West German MG3s or the Danish LMG M/62.[CfgVh 7][SCR 2]

How many belts an MG3 turret can have in reserve depends on the user at the time of its assembly. For instance, assembling the turret with eight belts in the user's inventory/backpack will provide the turret's gunner with one pre-loaded and have the other seven in reserve.

It is also possible to mix and match belts through this approach. If the user carried different belts at the time of assembly (e.g. DM21A1 and DM21A2), the turreted MG3 will be able to swap between them once it is mounted onto the tripod.

Ironsights[]

Arma3-gmcwgmg3-ironsight-overview

The MG3's ironsights allow for a minimum zeroing of 100 metres up to a maximum of 1,200 metres (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200).[CfgWp 9] It utilises a default setting of 400 metres.[CfgWp 20]

Arma3-gmcwgmg3-ironsight-specifics

It should be noted that attempting to adjust zeroing beyond 1,200 metres will enable access to the MG3's dedicated AA sight. This sight uses a fixed zeroing of 600 metres[CfgWp 9], though the user has the option of toggling three views.[CfgWp 10]

Arma3-gmcwglmgm62-ironsight-overview

The LMG M/62's ironsights allow for a minimum zeroing of 100 metres up to a maximum of 1,200 metres (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200).[CfgWp 21] The LMG M/62 always uses a default zeroing of 400 metres.[CfgWp 22]

Arma3-gmcwglmgm62-ironsight-specifics

It should be noted that attempting to adjust zeroing beyond 1,200 metres will enable use of the LMG M/62's dedicated AA sight. This sight uses a fixed zeroing of 600 metres[CfgWp 21], though the user has the option of switching between three views.[CfgWp 23]

Arma3-gmcwgmg3antiairtripod-ironsight-overview
The ironsights on static MG3s can be zeroed starting at a minimum of 100 metres up to a maximum of 1,200 metres (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200).[CfgVh 8] By default, the MG3's zeroing will always be set to 800 metres.[CfgVh 9]

It should be noted that the anti-air sight is not available on static MG3s. Zeroing is always capped to 1,200 metres (it will not jump to a dedicated 600 metres zeroing setting).[CfgVh 8]

Trivia[]

  • The MG3's accuracy was significantly reduced after the release of Update 1.1.3844[1].
  • The static turret variant was not included until the release of Update 1.2.[2]
  • After Update 1.5, handheld MG3s were given the ability to make use of a dedicated AA sight.[3]
  • Before Update 1.6's release, AI soldiers wielding any variant of the MG3 would share the same dispersion values with human players, allowing them to shoot with pinpoint accuracy no matter how distant the AI's target(s) were.[4]
The information below details unused, pre-release or removed content.
  • Arma3-render-gmcwgmg3desert

    Pre-1.5 Desert/Tan MG3.

    Prior to Update 1.5's release, the MG3 still had access to a Tan camouflage scheme, though it was only available for West German MG3s as Danish LMG M/62s were not configured to have alternate colour/camouflage schemes. The patch subsequently removed the Tan camouflage scheme but its classname remains intact for compatibility reasons.[3]
    • Since its texture no longer seems to exist within the DLC's files, equipping it through the use of a custom addon or scripting command will simply show it using a default Black colour scheme.[5]

Formulae

  1. ↑ 60 / reloadTime = 60 / 0.05
  2. ↑ Weapon's initSpeed * Magazine's initSpeed = 1 * 820
  3. ↑ initSpeed * caliber * 15 / 1000 = 820 * 0.9 * 15 / 1000
  4. ↑ initSpeed * caliber * 15 / 1000 = 820 * 0.9 * 15 / 1000
  5. ↑ initSpeed * caliber * 15 / 1000 = 820 * 0.9 * 15 / 1000

Notes[]

  1. ↑ The MG3's muzzle velocity is determined by the magazine's initSpeed value (the weapon itself only applies a multiplier).
  2. ↑ Dexterity is defined within the weapon's config but it does not apply since the MG3 is a static turret.
  3. ↑ 3.0 3.1 3.2 Damage will be reduced if the projectile's velocity drops below this value.
