Underbarrel grenade launcher (ArmA 3)

This article lists the specifications for underbarrel grenade launcher rounds featured on certain weapon platforms in ArmA 3.

Overview

Mk20 bullpup fitted with an EGLM.

Underbarrel grenade launchers are exclusively fitted onto the underbarrel rail of assault rifles in ArmA 3.

In stark contrast to ArmA 2's M203/GP-25 exclusive round system, UGLs now share from the same pool of grenade "magazines" irrespective of the launcher's design. There is no differentiation between a GLM mounted on a SPAR-16 rifle or an EGLM fitted onto the Katiba bullpup. All UGLs can load and fire the exact same types of grenades.

ArmA 3 is also the first game in the series to feature adjustable launcher sights. The sight's zeroing can be manually adjusted starting at a distance of 50 metres up to a maximum of 400 metres. Adjustments are usually made with increments/decrements of 25 or 50 metres depending on the UGL's current zeroing.

List of weapons with UGLs attached

The following weapon platforms all feature at least one or more sub-variants fitted with a UGL:

• AK-12 GL (7.62 mm)
• CAR-95 GL (5.8 mm)
• Katiba GL (6.5 mm)
• Mk20 EGLM (5.56 mm)
• MX 3GL (6.5 mm)
• Promet GL (6.5 mm)
• SPAR-16 GL (5.56 mm)
• TRG-21 EGLM (5.56 mm)

Of the eight platforms, the UGLs mounted on the MX, Katiba, Mk20 and TRG-21 all feature red dot quadrant sights for optics. Only the SPAR-16, CAR-95, Promet and AK-12 utilise conventional leaf/notched sights for aiming.

Grenade types

Parameter	HE	Flare (Signalling)	Flare (Illumination)	Smoke
Base damage value	80	5	5	0
Splash damage value	10	2	2	0
Warhead type	High-Explosive	Flare	Flare	Smoke
Blast radius (metres)	6	0.2	0.2	0.2
Muzzle velocity (m/s)	80	80	80	80
Duration (seconds)	Detonates on impact	25	45	60
Deflection angle (degrees)	5°	30°	30°	30°

• High-Explosive (HE): Inflicts High-Explosive-type damage to all targets caught in the blast radius. Has a blast radius of 6 metres.
• Flare (Signalling): Signalling/marking round. Burns for up to 25 seconds until the flare expires.
• Flare (Illumination): Illumination round. Burns for up to 45 seconds until the flare expires.
• Smoke: Concealment/marking round. The grenade will ignite 2 seconds after being launched. It takes approximately 10-15 seconds for a cloud to fully form. The grenade will continue to emit smoke for up to 60 seconds before it expires.

All single-shot grenade types share the same weight of 4 "mass" units. Only the unique 3-round grenade stack magazines have a weight of 12 "mass" units. These 3-round magazines are exclusive to the MX's 3GL and cannot be loaded into other 40 mm UGLs.

HE grenades have a minimum fuse range of 15 metres. The grenades will not detonate even if they come into contact with a hard surface unless the grenade flies beyond this distance.

Flares and smoke shells are available in a variety of colour and visibility spectrums:

• Flare: White, green, red and yellow. There is also a fifth IR variant but it does not actually require night vision goggles or a night vision-capable optic to see.
• Smoke: White, green, red, yellow, blue, orange and purple.

There are no performance differences between the colours. Both smoke and flares do not have a minimum fuse range.

Trivia

• 

  Close-up view of the GL 15A (left) and GP-25 (right) tubes; note the flat conical shape of both the 35 mm DFS and 40 mm VOG grenades in contrast to the spherical head on NATO-standard grenade rounds.

  No matter their country of origin, all UGLs in ArmA 3 can ubiquitously load and fire the same 40 mm grenade rounds despite the fact that several of the launchers would clearly be incompatible.
  • Though this is acceptable in the case of the 3GL, EGLM, UGP-40 and GLM launchers due to their real-world counterparts being designed with the 40×46 mm SR round in mind, it makes little sense for UGLs of Eastern origins to support being loaded with them. The real Chinese-made GL 15A ("Type 10") is designed to launch 35 mm DFS grenades which ARE NOT compatible in the slightest with the other NATO-standard UGLs. Likewise, the Russian GP-25 loads caseless VOG-25 rounds which would also not be able to fit inside Western-made UGLs.
  • To further compound the logic issues surrounding ArmA 3's penchant for ubiquitous grenade rounds, both the GL 15A/GP-25 are clearly modelled with non-NATO grenades loaded inside their tubes.
• When ArmA 3 was initially released, UGLs did not feature unique reload animations for each launcher and simply reused the same generic reloading animation.
  • Actual animations were finally added following the release of Game Update 1.54 as part of the free Nexus Update. However, some weapons like the MX 3GL still lack properly animated parts (the 3GL is reloaded as if it were a GP-25; in reality it is breech-loaded and not muzzle-loaded).
• Illumination rounds did not originally exist at ArmA 3's launch. They were only made available as launchable munitions in Game Update 2.20.
