Viper (alternately called Viper Team) is an elite CSAT special operations force. It was added to ArmA 3 with the release of the Apex DLC.


« CTRG has been tracking a clandestine network of CSAT operatives. We know them as 'Viper'.

Though their exact purpose remains highly classified, Viper are known to be an elite special operations unit that serves under the mandate of CSAT. They are specifically deployed for use in destabilisation ops against foreign countries with friendly relations to the West.

Often, this involves embedding themselves into anti-government organisations to sow havoc in targeted countries. Their activities range from supplying dissident groups with arms and equipment, along with sabotaging vital infrastructure such as power grids or utility services.

The exact composition or size of the force is not known, but it can be assumed that they are at least comparable to or are equal in numbers to their NATO counterpart.


No official information is known about Viper Team's date of organisation or activities prior to the 2030s.

It can however, be assumed that they have been active for at least a year prior to the events of the The East Wind, as Viper form a key component of CSAT's so-called "Apex Protocol" destabilisation efforts against Western nations.

Post-Apex Protocol

« The evidence has little basis in reality. Even so, the actions of a few individuals must not reflect upon the progress made by the whole.
Xu Haifeng, Supreme Commander of Pacific CSAT forces

The public exposure of CSAT's "Apex Protocol" has put the fate of the organisation (and Viper itself) into question as the United Nations immediately launched an inquiry into almost a decade of CSAT's unchecked expansionism across the globe.

In spite of the "Apex Protocol" revelations, both CSAT itself and Viper continue to exist.


Viper are granted access to the latest in CSAT's experimental and prototype hardware. Their signature outfit is a special combat suit that offers superior (even in comparison to standard-issue CSAT fatigues) protection to small arms fire, and also camouflage the wearer against thermal sensors. They wear advanced helmets that not only provide the best ballistic protection, but also grant Viper operatives with a full panoramic view of their surroundings in both thermal and night-vision.

Viper operatives exclusively utilise the Type 115, a bullpup dual-role assault rifle that is chambered to fire caseless 6.5 mm ammunition and can disable vehicles with its underbarrel .50 BW anti-materiel rifle module.

For ground and air transportation, they primarily rely on Qilin LSVs and the Y-32 Xi'an (respectively) in order to travel in and out of their areas of operations.
