Siege Extraction

"I've learned from experience that the place to save lives is in the field, not an office. And sometimes the only way to save a life, is to take one."
— Doc

Gustave "Doc" Kateb is a Defending Operator featured in Tom Clancy's Rainbow Six Siege.


Gustave Kateb was born on September 16 in Paris, France. Of Algerian and French descent, Kateb grew up in an affluent family in Paris' 16 arrondissement. He comes from a well-respected lineage in both the military and medicine. In his second year of medical studies with the prestigious Paris Descartes University, Kateb answered the appeal for volunteers in Médecins Sans Frontières (MSF). He has subsequently volunteered numerous times on emergency frontline aid missions around the world. At age twenty, Kateb declined a prominent private medical practice in favor of a career with the French Defense Health Service.

Kateb's main discipline is toxicology and ecotoxicology. He has authored studies on biological agents and their effects on at-risk populations and damaged environments, and contributed reports to the European Centre for Disease Prevention and Control (ECDC). Recognizing the ongoing need for doctors, Kateb continues to volunteer with MSF. He is a highly regarded medical officer for the French Army Special Forces Command.[1]

Psychological Profile

Kateb demonstrates a high degree of empathy for human suffering; he is a rare genuine altruist. He sees military service (especially the role of CTUs like the GIGN) as noble in their dedication to protecting civilians. He considers the front line his natural habitat, as it provides him with the opportunity to have direct influence and impact of the welfare of the unit. His proclivity for conflict resolution makes him a valuable asset.[2]

Psychological Report

Specialist Gustave "Doc" Kateb's wealthy upbringing could easily have turned him into a narcissist, yet he's one of the most accessible and thoughtful people I've encountered. Surprisingly, he didn't have much interest in being a doctor. The impetus seems to stem from family tradition, though it's clear his grandfather's military service was a strong motivation. Kateb admitted that he almost quit at the end of his first year because he didn't feel any passion for his work. I gather his father thought the mention of "passion" was absurd. […]

In his second year, Kateb volunteered for MSF and that first mission still resonates with him. The squalor, the chronic lack of supplies, the desperate need. He remembers how the look of worry on the mother's faces subsided as they gathered near the tents. That was when he found his passion at last. […] Encountering people with so little, it's understandable that Kateb said he felt shame. What's interesting is that he described embarrassment as well for the life he still had. […]

Field reports reflect Kateb's selfless acts, yet he has explicitly chosen a combat role. That piqued my interest. It was some time before he was willing to share his story with me. During a frontline op in East Africa, the hospital where Kateb worked was stormed by local militia. All of the patients he had fought so hard to save were killed. From this horrendous event he realized it was within his power to save lives with a scalpel or a bullet. […]

Kateb's proclivity for conflict resolution is just one of a dozen skills that make him an asset to Rainbow. It's clear the team trusts and respects him. He's developed a strong bond with Specialist Emmanuelle "Twitch" Pichon, due in part to Pichon's use of technology to lessen the risk on human lives. Unfortunately, there is also unresolved animosity with Specialist Olivier "Lion" Flament over quarantine procedures that saw several of Kateb's aid worker friends killed. For now, the situation is stable, if nonreciprocal. That may be the best we can hope for.

Gameplay Description

A Heavy Armored Operator, Doc's Unique Gadget is the MPD-0 Stim Pistol. It is able to revive and heal allies from afar.

  • The Stim Pistol heals 40 health to any Operator that Doc hits with it, including Attackers.
  • A Stim Pistol can Overheal a player beyond their health capacity (normally 100 health), granting an additional temporary health buffer beyond a player's normal maximum health. 
  • An Operator can only have up to 40 extra health from an Overheal (140 health), which decays at a rate of 1 health per second. 140 health is the maximum overheal health that can be obtained, even if multiple Stims are applied.
  • If Doc heals an attacker that is being affected by Lesion's Gu Mines, the Gu Needle will be removed from the attacker.
  • The Stim Pistol can revive any downed Operators from afar with a single shot.
  • If used to revive an Operator, it will revive them to 75 health, compared to a manual revive's 20.
  • In terms of health picking up an operator and then using a Stim on them would give 15 health less.
  • The revive process for the Stim Pistol is also shorter than a standard revive, taking only 2.75 seconds, compared to the regular revive time of 4 seconds.
  • When in hand, the action button (PS4: R1; XBOX: RB; PC: MMB) allows Doc to use the Pistol on himself, healing himself or even reviving himself if downed.
  • Pressing the action button again does not holster the Stim Pistol back to whatever gun Doc had switched out with. Meaning, he has to switch with the other action button (PS4: △; XBOX ONE: Y; PC: 1 (Primary) or 2 (Secondary)) to avoid accidentally using the Stim Pistol on himself.
  • Unlike other guns, the Stim Pistol's shots have a short travel time, though they do not have projectile drop.
  • The Stim Pistol shots can travel through bullet holes in walls.
  • The Stim Pistol also has pinpoint hip fire accuracy, thus not requiring to aim down sight to make accurate hits.
  • During a Multiplayer match, Doc only has 3 shots per round. In Terrorist Hunt, he has 5.



  • Doc works especially well with fellow GIGN defending Operator Rook and his Armor Plates, which grants those who wear the Plates heightened defenses and a greater chance of being downed than killed.

"Fires a hypodermic shot to revive himself or teammates from a distance. Can also provide a temporary boost."
— MPD-0 Stim Pistol Description

A handheld, trigger-operated pistol powered by a pressurized CO2 charge delivering a 1mg dose of epinephrine in a saline solution.

While careful close range medical care is obviously preferable in the case of a major combat injury, fast-paced real-world operations require a more flexible approach to treating field casualties. The reviving jolt that Doc administers with expert marksmanship can often spell the difference between mission success and failure when each second is precious.

The first thing we're taught in battlefield triage is MARCH, or looking for and treating in order: Major Hemorrhages, Airways, Respiration, Circulation, and Hypothermia. The first, blood loss, is always the greatest danger and while my stim pistol delivers the necessary dosage of epinephrine to stimulate the heart and dilate the cardiovascular system with adrenaline, the dose also includes micro-pellets that function as near-instant coagulating agents. They race through the circulatory system, sealing up internal bleeding and damaged blood vessels, and filling in wound cavities from the inside, preventing soldiers from bleeding out. I don't like the idea of keeping wounded soldiers on their feet, to be frank, but I also know that a soldier who can still fight will save more lives.

  • Doc is certified to practice in ten countries "Doctor's Without Borders"
  • Doc is at odds with fellow GIGN Operator and CBRN specialist Olivier "Lion" Flament, whose actions in an incident in West Africa in 2015 for reasons of safety caused the deaths of several medical personnel, including one of Doc's colleagues. Doc thinks Lion lacks the empathy necessary to help in medical crises, while the latter think's that the former's humanitarianism is a liability.[3][4]
