NOTE: This article is about the Protector submachine gun in ArmA 3. For the Protector Helmet worn by conventional CSAT soldiers, see Protector Helmet.

« A lightweight, air-cooled, selective fire, delayed blowback operated submachine gun with a roller-delayed bolt. The compact size, accuracy and high rate of fire of the Protector are highly regarded and the gun is used in many variants by numerous military, law enforcement, intelligence and security organizations all around the world.
Field Manual
The Protector 9 mm submachine gun.

The Protector is a 9 mm submachine gun used by both the Tanoan Gendarmerie and L'Ensemble guerillas in ArmA 3. It was added with the release of the Apex DLC.

The Protector is a compact submachine gun chambered to fire the 9×21 mm round that uses a delayed roller locked bolt operation.

It loads from 30-round curved box magazines, and can achieve a fire rate of up to 895 rounds per minute with a muzzle velocity of 375 m/s. The Protector accepts top and side rail accessories and can also mount muzzle attachments.

Performance-wise, the Protector is lacklustre and is completely outclassed by every other SMG. It does not have the negligible recoil of the PDW2000 when firing on full auto, the stopping power of the Vermin's .45 ACP round, nor the fire rate/accuracy of the Sting/ADR-97 SMGs.

Its sole upside is that it retains slightly more energy than the Sting at longer ranges. But even this advantage is redundant at best due to its poor accuracy and the fact that they are both chambered for the same 9 mm cartridge. As a result, the Protector effectively has no positive qualities that would justify it as a better option against other SMGs in its class.



The Protector's ironsights allow for manual zeroing between two fixed range settings (either 100 metres or 200 metres). By default, it is always zeroed to 200 metres. Neither the rear nor the front sight is illuminated.

If an optic is attached onto the top rail, the Protector will only allow it to be zeroed up to an absolute maximum of 200 metres. The optic cannot be zeroed beyond that range even if it supports a higher limit (e.g. DMS).[note 1]

The Protector supports four types of magazines. They all share the same weight of 10 "mass" units:

9 mm 30Rnd Mag[]


Standard 30-round translucent box magazine designed for use with the Sting but is also compatible with the Protector.

None of the rounds fired will emit visible tracers.

9 mm 30Rnd Reload Tracer (Red) Mag[]


Alternate 30-rounder magazine loaded with a mix of 9 mm ball and tracer ammunition. The last four rounds of the magazine will always emit red tracers.

9 mm 30Rnd Reload Tracer (Green) Mag[]


Alternate 30-rounder magazine loaded with a mix of 9 mm ball and tracer ammunition. The last four rounds of the magazine will always emit green tracers.

9 mm 30Rnd Reload Tracer (Yellow) Mag[]


Alternate 30-rounder magazine loaded with a mix of 9 mm ball and tracer ammunition. The last four rounds of the magazine will always emit yellow tracers.


  • The Protector is based on the real-world "MP5K" submachine gun designed by Heckler & Koch GmbH of Germany (parodied as a product of an Armaverse company named "Sovak Arms"), but is fitted with the stock of an "MP5K-PDW" instead.
    • The model itself appears to be an upgraded port of the "SG5-K" submachine gun from DayZ, another title developed by Bohemia Interactive.
  • The Protector was initially unable to mount side rail accessories despite the fact that it has rails modelled onto both sides of the handguard. This was later rectified with Game Update 1.66, which finally enabled accessories to be fitted onto those rails.[1]
  • As of Game Update 1.92, the Protector loads the same translucent magazines used by the Sting and can no longer share them with the PDW2000.[2] Since the Protector itself was not updated with the new magazine proxies system however, the appearance of its magazines do not change to reflect this.
  • Prior to Old Man, the Protector was exclusively utilised by the Gendarmerie. The mini-campaign's release would later show L'Ensemble anti-government fighters also using the SMG as part of their default arsenal.[3]



  1. In the case of certain optical sights that have minimum zeroing limits greater than 200 metres (such as the LRPS), the Protector will default to the optic's minimum zeroing even if it is higher than 200 metres. However, zeroing settings will not be adjustable until the optic is removed.
