Deadly anomalies, dangerous mutants, anarchists and bandits... None will stop Duty on its triumphant march towards saving the planet!
- Duty propaganda aired on their intercom system

Duty (Долг) is a paramilitary clan of stalkers operating in the Zone with members living according to a code. They, along with Freedom, are also one of the most powerful stalker clans in the Zone. They appear in S.T.A.L.K.E.R.: Shadow of Chernobyl, S.T.A.L.K.E.R.: Clear Sky and S.T.A.L.K.E.R.: Call of Pripyat.


The founding members of Duty, as well as many of its subsequent members, were originally Ukrainian Military troops and Special Forces units sent into the Zone and left to die there after being nearly killed by the Zone's mutants and anomalies. Other members are ordinary stalkers who have seen enough of the Zone's horrors, and have decided to do something about it. Duty sees the Zone as an ulcer in the world that must be purged at all costs, as they believe that if left unchecked, mutants will soon break out of the Zone and attack the outside world. They achieve this by killing all of the Zone's manifestations, namely Mutants, in the process bringing them into conflict with factions such as Freedom, who believe the Zone is something beneficial. Duty also fights against other factions such as the Bandits and Mercenaries, who extort Stalkers for personal gain. With superior equipment and fervently dedicated members, they fully intend to achieve their goal.

Duty is at odds with everyone seeking to exploit the Zone and, as Duty sees it, spread its corruption. They opt for the complete destruction of the Zone through brute force, effectively attempting to "kill" the Zone. They are contrasted by other factions, such as Freedom or the Ecologists, who see the Zone as a miracle. They tolerate Loners, but are hostile towards Freedom faction members, seeking to undermine their efforts at every step. They also openly engage Bandits due to their hostility and extortion of free Stalkers.

They are, however, openly cooperating with the Ecologists at Yantar, transferring all recovered artifacts to them; so that the Zone can be better understood (and, as Duty wishes, defeated).

The faction has long been in fierce conflict with Freedom due to their conflicting ideals.


SHOC Dutyer

A Dutyer, ca. 2012

Duty is primarily made up of the survivors of military expeditions into The Zone, sent to take its territory under governmental control in the wake of the very first stalker incursions in 2009. Anomalies and mutants caused many casualties, while those who managed to survive eventually made their way to the Rostok Factory, where they stayed, fighting off monsters and coping with hunger and deprivation.

Duty was founded by then Captain Tachenko, the squad leader of a team of specialists who were tasked to destroy the center of the zone using nuclear explosives however were nearly wiped out by an emission that followed. A Captain at the time, he and his closest officers staged a communications breakdown, allowing them to desert the army and join stalkers in exploiting the Zone. While this ploy worked, the resulting chaos led to great casualties among soldiers, although it enabled Tachenko to create Duty.

Tachenko was never held accountable, the story effectively silenced by he and the other higher ups. During a routine artifact hunting trip, however, he and his fellow conspirators were trapped in a spatial anomaly. While they searched for a way out of the anomaly, a Colonel suffered a nervous breakdown and shot two other Duty officers before Tachenko could take him down.

With its original leader lost, General Krylov, one of the soldiers that served with Captain Tachenko in their failed mission, assumed leadership and set up a base of operations in the Agroprom Research Institute, initiating their research into the nature of the mutants the Zone breeds. The clan avoided contact with the military for obvious reasons. However, it should be noted that there were reports of stalkers dressed in black suits dealing with Ukrainian Spetsnaz troops.

Their research, while progressing slowly at first, was launched forward with the discovery of the archives beneath Agroprom, containing a plethora of new information (mostly pertaining to Soviet mind control experiments performed on local wildlife, and research performed on behalf of the Group focusing on the C-Consciousness project).

In 2012, Duty abandoned the Agroprom institute, relocating their base of operations to the Bar area in the Rostok Factory. Their wrap up was thorough, leaving only an empty shell of a building behind... and a nice, elegant rundown of their investigation into the activities of the Group in the Zone, to be recovered by Captain Maksimienko. Their war with Freedom did not escalate, as with General Krylov's resignation and Brigadier General Voronin's assumption of command, they pursued a policy of remaining static - they would continue to fight with Freedom, but would not actively seek to destroy them.

After Strelok opened the way up North, Duty and Freedom both sent a contingent to the Yanov station, while General Voronin continued to command his forces from a reinforced bunker within the Rostok Factory.


Duty is a well organized faction, with a strict hierarchy and bureaucracy. Every member has a rank assigned to him (based on military ranks) and clearly defined responsibilities. Equipment is cataloged and marked with serial numbers, while all sensitive data is encrypted, to prevent non-Duty personnel from accessing it. Apparently when becoming a Duty member one has to take an oath. This is it's content, based on Marked One's example (which would ironically influence his beliefs later in Call of Pripyat):

I, a stalker known as the Marked One,

swear to defend the goals and ideals of Duty.

To protect the Earth from the dangers of the Zone, to seek out and destroy anything it spawns within and beyond its borders.

To fight any nonconformists, be they individual stalkers or groups.

And to give my life in the name of justice and order on Earth!''
- Marked One's oath.

Notable membersEdit


Duty is one of the best equipped factions. As former Ukrainian Military operators, they prefer to use Soviet weaponry, which is yet another example of how they oppose Freedom, who prefer NATO weaponry.



  • PS5-M Universal Protection - a basic, lightweight stalker suit commissioned by Duty.
  • PSZ-9d Duty suit - a lightweight stalker suit commissioned by Duty. Offers good protection from anomalies and can stop pistol rounds. Comparable to the Guardian of Freedom Suit in Shadow of Chernobyl.
  • PSZ-9Md Universal Protection - Duty's variant of the SEVA Suit. Only obtainable for the player in Shadow of Chernobyl, but it is worn by Duty members in all three games. Has a great protection against radiation, anomoly, and a pretty decent bulletproof protection.
  • PSZ-9d Duty Armor - Duty's variant of the SKAT-9M Military Armored Suit. Features better protection from bites/scratches and better bulletproof than Guardian of Freedom Suit, with slightly worse protection from anomalies and radiation. Only available in Clear Sky and Call of Pripyat.
  • Duty Exoskeleton - Exoskeleton in Duty colors. Unobtainable to the player in all three games.


Shadow of ChernobylEdit


Duty wears characteristic black hazardous environment suits with red elements, primarily on their bulletproof vests. Their weapons are usually those of the former Warsaw Pact, including (but not limited to) the AK-74, OC-14 Groza (most common), Dragunov SVD and SVU variants and the AN-94 Abakan. Overall, they are among the best equipped factions in the Zone.

Clear SkyEdit

In Clear Sky, members of the faction come in several different flavors, ranging from the simple rank-and-file Dutyers, equipped with basic armor and weapons, to the mighty dreadnoughts clad in Exoskeletons. All carry either a Fort-14 or Makarov PM as a sidearm.

Call of PripyatEdit

Duty forces are located in Yanov, along with Freedom forces. Their HQ is located at the Yanov train station, where they share it with Freedom as a 'no fire' zone. In addition, the Loners there will act as a buffer between Duty and Freedom. Occasionally, the player may encounter small skirmishes between both factions outside of Yanov station. It is the player's choice to either assist Duty or Freedom, or leave them to their war.

Behind the scenesEdit

Development and cut contentEdit

  • Originally, Duty didn't wear black and red uniforms - instead, they had green-and-brown ones, a design later given to members of the Monolith faction.
  • According to the original website, Duty was supposed to give the Marked One an assignment, which included travelling to the Swamps and taking out the Phantasm, a mutant that could create phantom images to attack stalkers.
  • In the original STALKER SHOC website and in their script designations, they are called "Dolg" (The Romanized Cyrillic Word for Duty)
