The Sound Suppressor is a muzzle-fitted weapon attachment in ArmA 3.

Overview

NATO marksmen wielding a suppressed Mk18 ABR (left) and MXM (right).

Suppressors are designed to be fitted onto the muzzle of firearms. Once attached, the suppressor will alter the sound signature of the weapon and make it harder for enemies within range to hear the discharge.

Suppressors will also minimise (not remove) the weapon's muzzle flash, which can help prevent the shooter's position from becoming exposed at nighttime and prevent said shooter from being blinded. In addition, suppressors will enhance the velocity of a weapon slightly which can provide a small boost to its effective firing range.

It should be noted that sound suppressors are only interchangeable between firearms that are chambered for the same calibre. They will also inflict a higher inertia penalty on the user and do not reduce weapon recoil. In addition, not all weapons can actually be fitted with sound suppressors. Certain weapons lack threaded barrels and are incapable of mounting them (i.e. the AKM assault rifle or AKS-74U carbine).

Lastly, ammunition fired through suppressors remain at supersonic speeds and will emit an audible crack. Unlike in ArmA 2, subsonic ammunition is not available outside of specific weapons with integral suppressors.

Variants

NOTE: Except for where they are explicitly stated to be different, all sound suppressors increase muzzle velocity by 5%, decrease muzzle flash by 90%, audible distance range by 96%, and reduce weapon dispersion by 20%.

The 5.56 mm suppressor is designed to be used on weapons chambered to fire the 5.56×45 mm NATO round:

5.56 mm suppressors have a weight of 8 "mass" units. They are available in either a Black, Khaki or Sand colour finish.


5.7 mm

The 5.7 mm suppressor is designed exclusively for use on all variants of the ADR-97 bullpup submachine gun. It is only available in a Black finish.

There are few performance differences compared to regular 5.56 mm suppressors, save that the 5.7 mm variant only reduces muzzle flash by half (50%) and provides a 70% sound reduction as opposed to 96% (which is the baseline standard).

Appearance-wise, it is identical to that of the 9 mm suppressor but inflicts twice the amount of inertia penalty. 5.7 mm suppressors have a weight of 10 "mass" units.


5.8 mm

The 5.8 mm suppressor is designed solely for use on weapons chambered to fire the cased 5.8×42 mm round:

It is available in either a Black, Green Hex or Arid Hex camouflage finish, and has a weight of 8 "mass" units.

The 5.8 mm suppressor is unique for being able to conceal its heat signature and will not light up on infrared sensors during and after continuous fire.

However, it should be noted that some heat will eventually seep through and become visible on thermal optics if the weapon has not been given enough time to cool down after prolonged fire.

Performance-wise, there are no other differences when compared to the 5.56 mm suppressor.


6.5 mm

The 6.5 mm suppressor is designed for use on all firearms chambered for the 6.5×39 mm round (both NATO and non-NATO, regardless of whether it is cased or caseless):

A separate variant LMG variant is also available for use and shares the same appearance of the regular 5.56 mm suppressor. There are no functional differences compared to the regular 6.5 mm suppressor, however.

6.5 mm suppressors are available in a Black, Khaki or Sand colour finish. They all have the same weight of 10 "mass" units.


Stealth

The Stealth Sound Suppressor is a unique suppressor variant that is designed specifically for mounting on the CMR-76 and Type 115 marksman/special purpose rifles.

However, it should be noted that several other 6.5 mm-chambered firearms - both of CSAT and non-CSAT in origin, may also mount a Stealth Sound Suppressor:

Like 5.8 mm suppressors, the Stealth Sound Suppressor absorbs heat and will not emit a thermal signature on infrared optics. This will remain the case even after sustained bursts, though it should be noted that extended periods of fire without allowing the weapon's barrel to cool down will eventually cause some heat to seep through.

It is available in either a Black, Green Hex or Arid Hex camouflage finish, and has a weight of 8 "mass" units. Note that the Stealth Sound Suppressor is not capable of suppressing the Type 115's underbarrel anti-materiel rifle module.

The 7.62 mm suppressor is freely interchangeable on all 7.62 mm-chambered weapons regardless of whether it fires 7.62×39 mm, 7.62×51 mm NATO or 7.62×54 mm:

It is available in either a Black, Khaki, Sand, Arid or Lush finish. No matter the variant, 7.62 mm suppressors have a weight of 12 "mass" units.


.338

Games
A3-marksmen.png

The .338 suppressor is intended for use on weapons chambered to fire the .338 round (8.6×70 mm), both Lapua Magnum and Norma Magnum:

  • MAR-10 marksman rifle
  • SPMG general-purpose machine gun

They are available in a Black, Green or Sand colour scheme, and have a weight of 10 "mass" units.

It should be noted that .338 suppressors specifically increase the muzzle velocity of the weapon by 10% rather than 5%. There are otherwise no other performance differences when compared to to conventional suppressor designs.

Compact and light to attach, the 9 mm suppressor is compatible with most weapons that are chambered to fire the 9×21 mm round:

It is only available in a Black finish and only weighs a total of 6 "mass" units.


9.3 mm

The 9.3 mm suppressor is designed exclusively for weapons chambered for the 9.3×64 mm round:

  • Cyrus marksman rifle
  • Navid general-purpose machine gun

It is available in either a Black or Tan finish. The 9.3 mm suppressor has a weight of 12 "mass" units.

When fitted, the 9.3 mm suppressor will increase the muzzle velocity of the parent weapon by 10% rather than 5%. There are otherwise no performance differences when compared to other suppressors.

Notes

  • Certain suppressor variants are compatible with weapons featured in third party-developed Creator DLCs. Please note that they are deliberately excluded from this article as they are not considered to be official content.

Trivia

  • On release, ArmA 3's sound suppressors applied extremely unrealistic attributes onto the weapons that they were mounted on:
    • They were able to somehow decrease the damage of bullets fired by the weapon (despite the lack of subsonic ammunition in ArmA 3).
    • They nonsensically reduced the weapon's muzzle velocity rather than increase it.
    • They did not decrease the weapon's dispersion or lower its recoil.
  • Additionally, they also caused all weapons to share the same firing sounds as each other (i.e. a suppressed TRG-20 with the 5.56 mm variant would sound the same as a suppressed Mk20C). Furthermore, many suppressors shared the exact same models and lacked camouflage variety.
    • The former issues were subsequently fixed in later overhaul updates both prior to and after the Marksmen DLC's release.
    • Unique models and camouflage finishes on the other hand, were not changed until the release of the Apex expansion.

Unused sound suppressor model, specifically for the 4-five pistol.

  • An alternate .45 ACP pistol suppressor model remains unused within the game files. Modelled after the real-world "Osprey" designed by Utah-based manufacturer SilencerCo, it would have supposedly been used for the 4-five pistol (Model name: acca_snds_osprey_f.p3d).
    • Likewise, the Vermin SMG also has an unused model which was presumably intended for its exclusive use, though its unused model (Model name: acca_mzls_smg_01_f.p3d) is strangely prefixed as a flash suppressor rather than for sound.

Unused Flash Suppressor icons for 6.5 mm (left) and 9 mm (right) weapons.

  • As seen in many of the pre-Alpha screenshots released to promote ArmA 3, flash suppressors for both rifles and sidearms were intended to have been included in the final game.
    • Based on their appearance, they were modelled after the "KX" series of flash hiders designed by Noveske Rifleworks LLC.
    • Models and inventory icons (Model name: acca_mzls_h_f.p3d) for both flash hiders still exist in the game files, though it's not known as to why they were excluded from the final game.
  • Following the release of the Contact expansion pack, the Stealth Sound Suppressor was made available to both the MX and Promet families of rifles as well. Oddly enough, no other 6.5 mm-chambered weapons like the Mk200 could be fitted with the suppressor (not even CSAT's own Katiba bullpup was able to utilise them).
    • Prior to Game Update 2.02, several of the suppressors like the Apex expansion's Stealth Sound Suppressor were rendered incompatible or were strangely excluded from weapons which were able to support mounting them by default.
    • The patch corrected this inconsistency and resolved underlying issues leftover from Game Update 2.00, such as allowing Katiba bullpup or Mk200 LMG to mount the Stealth Sound Suppressor.
