Military Stalkers can be either expert Stalkers that have been contracted by the Ukrainian Military and have received military training and equipment - or Ukrainian Special Forces who have specialized experience operating inside the Zone. In the games they are typically ranked as experts, and may or may not sport Military Ranks attached to their names. 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.
Soldiers who underwent special training following their service in the Zone or stalkers who voluntarily signed a contract with the Army. Usually equipped with various support gear and well-armed. Used mainly to study the causes and effects of the catastrophe and to map out the Zone. They can work on their own or in small detachments of up to five people. Military stalkers do not allow normal stalkers to approach and open fire on sight.Shadow of Chernobyl PDA description
Typically working alone or in small groups of up to five team members, military stalkers are typically Zone veterans contracted by the military for special operations or Spetsnaz soldiers, who underwent specific training preparing them for combat drops in the Chernobyl area.
Military stalkers typically work in tandem with Spetsnaz operators, most often leading them into combat. They may also work in a squad composed entirely of military stalkers.
Military stalkers are either former stalkers contracted by the military, or actual active members of the military with extensive experience in the Zone. As such, they are valuable assets in the field, possessing extensive knowledge about artifacts, anomalies, and the Zone itself. For this reason Military Stalkers are given the best equipment that the Military has to offer. They often wear high-end SKAT-9M Military Armored Suits and Sphere-12M Helmets in the FLORA pattern, protective gear suited to combat in highly anomalous areas. Military Stalkers also utilize high-end Soviet weaponry, such as the SA Avalanche and Tunder S14 assault rifles. In addition to high-end firearms they have been known to use expensive F1 Grenades, allowing them to engage enemies at a distance with deadly force.
- Skat-9M military armoured suit: High-end armored suit designed specifically for use in the Zone. Features a PSZ-12p bulletproof vest, a built in compensation suit, and a Sphere-12M Helmet. Bullet/shrapnel protection is equal to that of the PSZ-12D Duty Armor and second only to the Exoskeleton. Protection from radiation and anomalies is above average. While this is the newest variant of the suit, it appears that it was only issued to the battalion that was present in Shadow of Chernobyl as it is not present anywhere else.
- Skat-9 military armoured suit: Also known as the "Bulat" armored suit and the current armor of Military stalkers at large. While older than the SKAT-9M, the suit still retains a high amount of protection and durability comparable to its successor.
Military Stalkers are only deployed in areas considered too hazardous for regular Military forces, and thus are not encountered until the later stages of the games.
During the course of Clear Sky's campaign, a small detachment of Military stalkers, along with the remnants of a Spetsnaz team was stranded in the Army warehouses. Another Military stalker was deployed into Limansk, leading a large squad of Spetsnaz operators.
Shadow of Chernobyl
Large units of Military Stalkers are deployed into Pripyat and the Chernobyl NPP area after Strelok disables the Brain Scorcher. At the Chernobyl NPP, they are supported by Mi-24 Hind Gunships and BTR-70 Armoured Personnel Carriers. Some Military Stalkers will appear at Cordon when you have deactivated the Brain Scorcher.
Call of Pripyat
The protagonist of Call of Pripyat, Major Degtyarev, is in practice a Military Stalker. Other, better equipped Military Stalkers later appear in Pripyat alongside conventional Spetsnaz as part of Colonel Kovalsky's rag-tag group of Military survivors, and the Quartermaster can hand the Major a typical Military Stalker uniform. Despite being significantly more experienced than the Grunts and even Spetsnaz they landed with, however, most are inevitably killed in Pripyat.
- Until the events of S.T.A.L.K.E.R.: Shadow of Chernobyl, Military Stalkers were highly secretive in their dealings. Thrush mentions rumors of Stalkers clad in black suits working with the Military, who were rumored to have mutual connections with some Dutyers.
- Spetsnaz — Ukrainian Special Purpose Regiments. Military Stalkers are classified as "Spetsnaz", being elite troops acting under the Ukrainian Government - though they are actually elite mercenaries rather than actual Ukranian military personnel.
- Military — The Ukrainian Internal Security Service. Military Stalkers are contracted by the Military for their services.
