TRG-20

«

The TRG-21 is a bullpup assault rifle used by the FIA. It features an ergonomical design that supports accurate fire in harsh conditions. TRG-21 is lightweight, ambidextrous, easily serviceable and compatible with a large number of accessories. TRG-21 EGLM is mounted with an enhanced grenade launching module. A carbine variant is labeled TRG-20. Compared to TRG-21, it features a short barrel better suited for close quarters combat situations.

Field Manual^[1]

The TRG-20 is a 5.56 mm bullpup carbine used by both Altian government Loyalists and FIA guerillas in ArmA 3.

Overview[]

The TRG-20 is a carbine variant of the baseline TRG-21. As with its parent weapon, it is chambered to fire 5.56×45 mm NATO ammunition.

It loads from the same 30-round STANAG magazines used by the TRG-21 rifle, and can attain a fire rate of up to 750 rounds per minute^{[CfgWp 7]}^{[Formula 1]} but has a lower muzzle velocity of 840 m/s instead.^{[CfgWp 8]} The TRG-20 has the same ability to mount accessories on its top^{[CfgWp 9]} and side^{[CfgWp 10]} rails, and can also be fitted with a 5.56 mm sound suppressor.^{[CfgWp 11]}

The TRG-20 is ideal for use in close quarters thanks to its shorter barrel which imposes a reduced inertia penalty (0.3 versus the TRG-21's 0.4).^{[CfgWp 5]} With a weight of only 60 "mass" units (a~ 15% reduction in weight compared to its parent rifle)^{[CfgWp 3]}, the TRG-20 is also one of the lightest primary weapons in ArmA 3. Most notably, it is both small and light enough to fit into a Leg Strap Bag, meaning that snipers can bring it along as a backup weapon if necessary.

However, because its barrel length has been cut, its accuracy is poorer since its dispersion has been significantly increased by up to ~ 28%. This similarly results in a lower muzzle velocity of 840 m/s (a reduction of ~ 9%). Combined with the high air drag of its 5.56 mm ammunition^{[CfgAm 1]}, the TRG-20 has an effective firing range of no more than 400 metres.

Ironsights[]

The TRG-20's ironsights can be zeroed starting from a minimum of 100 metres up to a maximum of 600 metres (100, 200, 300, 400, 500, 600).^{[CfgWp 12]} By default, it is set to a zeroing of 200 metres.^{[CfgWp 13]} Both the front and rear sight are illuminated; the front sight post features an illuminated dot while the rear sight has strips on all four sides of the ring. They emit a pale green glow in daytime but appear brighter under low-light conditions.

If an optical sight with a zeroing limit greater than 600 metres is attached onto the top rail (e.g. Nightstalker), the TRG-21 will allow for an absolute maximum zeroing of 800 metres.^{[CfgWp 14]}

Ammunition[]

NOTE: Due to the TRG-20's reduced muzzle velocity, fired ammunition will always scale to an initial velocity of 840 m/s instead.

TRG-20s can load up to six types of magazines.^{[CfgWp 15]} All of its magazines share the same weight of 8^{[CfgMa 4]} "mass" units. They are available in either a Black or Sand colour finish.

It should be noted that although these STANAG magazines are interchangeable with any 5.56 mm NATO-chambered weapon (Mk20/SDAR/SPAR-16), 150-round drums utilised by the SPAR-16S cannot be loaded into the TRG-20:

5.56 mm 30rnd Reload Tracer (Yellow) Mag[]

30-round STANAG magazine loaded with a mix of 5.56 mm NATO ball and tracer ammunition.^{[CfgMa 5]}

The last four rounds of the magazine will always emit visible yellow tracers.^{[CfgMa 6]}

5.56 mm 30rnd Reload Tracer (Red) Mag[]

Alternate STANAG magazine that is also loaded with 5.56 mm NATO ball ammunition. Where it differs is its usage of red-coloured tracers as opposed to yellow.^{[CfgMa 7]}

Aside from firing different coloured tracers, it remains statistically identical to the standard yellow tracer STANAGs (the last four rounds of the magazine will always emit red tracers).^{[CfgMa 8]}

5.56 mm 30rnd Reload Tracer (Green) Mag[]

Alternate STANAG magazine that is also loaded with 5.56 mm NATO ball ammunition. Where it differs is its usage of green-coloured tracers as opposed to yellow.^{[CfgMa 9]}

Aside from firing different coloured tracers, it remains statistically identical to the standard yellow tracer STANAGs (the last four rounds of the magazine will always emit green tracers).^{[CfgMa 10]}

5.56 mm 30rnd Tracer (Yellow) Mag[]

Dedicated 30-rounder STANAG magazine loaded exclusively with 5.56 mm NATO yellow tracer ammunition.^{[CfgMa 11]}

Aside from its tracer-exclusive loadout^{[CfgMa 12]}, this magazine is statistically identical to the standard mixed load 5.56 mm STANAGs.

5.56 mm 30rnd Tracer (Red) Mag[]

Alternate STANAG magazine loaded with red tracer ammunition instead of yellow.^{[CfgMa 13]}

Other than its red tracer-exclusive loadout^{[CfgMa 14]}, this magazine is also statistically identical to the standard mixed load 5.56 mm STANAGs.

5.56 mm 30rnd Tracer (Green) Mag[]

Alternate STANAG magazine loaded with green tracer ammunition instead of yellow.^{[CfgMa 15]}

Other than its green tracer-exclusive loadout^{[CfgMa 16]}, this magazine is also statistically identical to the standard mixed load 5.56 mm STANAGs.

Trivia[]

Like its parent counterpart, the TRG-20 is directly based on the "Tavor" family of bullpup weapons designed by Israel Weapon Industries (IWI). More specifically, it is based on the "CTAR-21" which is a short-barrelled variant of the baseline "TAR-21" rifle.
Before the release of Game Update 1.22, dispersion values on the TRG-20 and TRG-21 were strangely reversed. Prior to the patch, the TRG-20 (carbine) was more accurate than the TRG-21 (rifle).^[2]
- The patch also increased the weight of the TRG-20. During the Alpha and up until the patch's release, the TRG-20 was one of the lightest primary weapons in ArmA 3 as it only weighed 30 "mass" units (as a comparison, it was as light as the PDW2000 despite the fact that the TRG-20 is a carbine).^[2]

Formulae

↑ 60 / reloadTime = 60 / 0.08
↑ Magazine's initSpeed * Ammo's caliber * 15 / 1000 = 920 * 0.869565 * 15 / 1000
↑ Weapon's initSpeed * Ammo's caliber * 15 / 1000 = 840 * 0.869565 * 15 / 1000
↑ Magazine's initSpeed * Ammo's caliber * 15 / 1000 = 920 * 0.869565 * 15 / 1000
↑ Weapon's initSpeed * Ammo's caliber * 15 / 1000 = 840 * 0.869565 * 15 / 1000

Notes[]

↑ ^1.0 ^1.1 This muzzle velocity value only applies to the magazine itself. Although the TRG-20's initSpeed value is lower (840 m/s), it takes precedence over the magazine's initSpeed value (920 m/s) since it is not defined as a coefficient (the weapon's initSpeed overrides the magazine's initSpeed since it is not a multiplier).
↑ ^2.0 ^2.1 This is the TRG-20's actual muzzle velocity. The weapon class initSpeed value (840 m/s) takes precedence over the magazine initSpeed value (920 m/s).
↑ ^3.0 ^3.1 Damage will be reduced if the projectile's velocity drops below this value.
↑ ^4.0 ^4.1 This is the actual penetration depth of the TRG-20's 5.56 mm ammunition. The weapon class initSpeed value (840 m/s) takes precedence over the magazine initSpeed value (920 m/s), affecting its penetration formula as a result.
