RCO

Sign in to edit

The RCO (full name: Rifle Combat Optics) is a low-powered riflescope used exclusively by NATO forces in ArmA 3.

Design[]

The RCO uses an illuminated crosshair reticle which is opaque enough to be seen when using thermal vision. It is optimised for all weapons chambered to fire the 6.5 mm NATO/non-NATO cartridge (both caseless and cased).[note 1] This includes:

  • CMR-76 bullpup marksman rifle (6.5 mm)
  • Katiba bullpup rifle (6.5 mm)
  • Mk200 light machine gun (6.5 mm)
  • The MX series of modular rifles (6.5 mm; all sub-variants)
  • The Promet series of modular bullpups (6.5 mm; all sub-variants)
  • Type 115 special purpose rifle (6.5 mm-chambered rifle component only; does not apply to the underbarrel .50 BW anti-materiel rifle module)

The main scope has a fixed magnification strength of 2x[CfgWp 1][CfgWp 2][Formula 1] and also uses a fixed zeroing setting of 300 m.[CfgWp 3][CfgWp 4] The primary scope's lens are thermally transparent; 'hot' targets will be visible through the sight if the user is wearing thermal vision-capable goggles.

The RCO also has a backup reflex sight with a red dot reticle that can be switched over to for use in close quarters. The backup reflex sight is set to a (also fixed) zeroing of 200 m[CfgWp 5][CfgWp 6] but its lens is thermally opaque ('hot' targets will not be visible when viewed with thermal optics).

It should be noted that RCOs will increase the inertia penalty of the weapon that it is mounted onto by +0.1.[CfgWp 8]

AI[]

NOTE: The information in this section only applies to the AI.

The RCO is classified[1] as a type 1 optical sight.[CfgWp 9] If the weapon is configured with AI-only firemodes[2], AI units that have the RCO mounted onto their weapon will have access to medium range firemodes but not far (type 2) range firemodes.[3]

Camouflage[]

  • Black: Standard matte black finish. Used by both Mediterranean and Eastern European NATO forces.
  • Khaki: Forest green paint finish. The reflex sight, scope mount, and turrets/dials are coloured in black. Exclusive to Pacific NATO forces.


Western Sahara Creator DLC only

NOTE: The following camouflage schemes will only be available if the third party-developed Western Sahara Creator DLC is activated.

This is a premium asset that requires ownership of the Western Sahara Creator DLC.

  • Arid: Desert camouflage pattern.
  • Lush: Woodland camouflage pattern.
  • Sand: Desert sand paint finish. The reflex sight, scope mount, and turrets/dials are coloured in black.
  • Snake: Snakeskin-style spraypaint camouflage pattern.


Trivia[]

  • The RCO is based on the real-life "Mark 4 High Accuracy Multi-Range Riflescope" manufactured by Leupold Optics. The top mount red dot sight on the other hand is based on Leupold's "DeltaPoint Reflex Sight".[4]
  • The Khaki RCO variant was not added until the release of the Apex expansion pack.[5]
  • After the Marksmen DLC's release, the top-mount reflex sight was upgraded to make use of the then-new collimator tunnelling effect[6] for its reticle (as part of Game Update 1.42).[7]
  • In previous versions of ArmA 3, the reticle markings on the primary scope would become extremely blurry and difficult to read under specific lighting conditions if depth of field was enabled in the player's graphics settings.
    • This was eventually corrected in a hotfix for Game Update 2.02, changing the RCO's model to use radial blurring instead of DoF.[8]
  • A unique Defunct variant (Classname: optic_Hamr_broken) exists exclusively for use in the First Contact campaign which has both the red dot and illuminated parts of the scope's reticle disabled due to storyline events.[9]
    • However, it cannot be equipped outside of the campaign even with the use of scripting commands, as it is only enabled if the player activates the optional Contact module of the expansion pack.
The information below details unused, pre-release or removed content.
  • When ArmA 3 was initially launched in Alpha, the RCO functioned as a traditional, ArmA 2-style 2D scope rather than 3D. The Beta's release would eventually replace it with its current 3D-style model instead.[10] Its original 2D scope reticle is still available in the game files[11], though it remains unused since the RCO no longer requires it.

Notes[]

  1. ↑ The RCO is technically compatible with 7.62 mm NATO-chambered firearms as well. However, the AK-12's (non-NATO) 7.62 mm cartridge will not be compatible due to the latter's greater bullet drop, particularly against targets located beyond 400 metres.
