"Mobile Task Force Unit Epsilon-11, designated Nine-Tailed Fox, has entered the facility. All remaining survivors are advised to stay in the evacuation shelter, or any other safe area, until the unit has secured the facility. We'll start escorting personnel out when the escaped SCP's have been re-contained."

MTF Epsilon-11 ("Nine-Tailed Fox") is a Mobile Task Force squad composed of nine units separated into 3 groups. In SCP - Containment Breach, their primary task is to handle containment breaches by re-containing all active, hostile SCP instances, rescuing surviving Foundation personnel and terminating any rogue Class-D personnel.


Mobile Task Forces are groups of specially-armed forces dedicated to the Foundation, with each Task Force group performing specific functions. The amount of units in an individual squad can range from 3 to over 20. Each Task Force is assigned a unique combination of a Greek letter and a number. 

Mobile Task Force E-11 ("Nine-Tailed Fox") is an intensively trained Task Force specializing in the protection and recontainment of SCP items kept at Site-█. They are the primary MTF unit encountered in SCP - Containment Breach and are comprised of nine members, each member representing and identified as one tail in the group's namesake. They are identical to the Site Guards except having navy blue fatigues and the Mobile Task Force symbol located on their ballistic vest. They are also the only enemies who interact with the player's body in a death message.

In-game SPOILERSEdit

When the player finds themselves in the nearby vicinity of a site exit, the intercom will announce that the task force has entered the facility. At this point, the MTF will enter the site from the Gate A entrance. Once inside, the MTF will begin wandering around the site and upon locating the player, they will open fire at them, making them an active threat.

The player must use any means possible to avoid getting killed by them, be it by running from them or even crouching to hide. The Nine-Tailed Fox cannot go through Tesla gates without using the radio and communicating with their commander to deactivate the Tesla gates before proceeding, so the player can use the gates as a means of eluding the MTF.

If the player is shot but manages to escape, they will begin to bleed. If the player does not use a first aid kit or an SCP-500 pill to treat the wounds, they will die from blood loss. The amount of damage and blood loss is determined by where the player is shot, with headshots being an instant kill. However, the player can use a ballistic vest in order to protect themselves better from incoming fire. Be warned, as the vest will not protect the head or the legs, and getting hit in the torso will still cause injuries and deplete the player's stamina, making escape more difficult.

As far as interacting with NPCs goes, Nine-Tailed Fox will re-contain SCP-173 when they come in contact with it by using a steel cage. They will also re-contain SCP-106 upon locating it's containment chamber. In the event that they encounter SCP-049, one of them will be affected by his lethal touch, and the others will back off and flee. If the player is caught by SCP-049, a cutscene plays where the player, now an instance of SCP-049-2, will be seen hobbling toward an MTF soldier. Shortly after, the MTF shoots the player, killing them. In addition, in the rare event they encounter SCP-096 they will activate their SCRAMBLE gear. If they encounter an SCP-008 instance, they will also open fire on it.    

WARNING: The following may contain spoilers about the game.

When approaching Gate A, a group of MTFs will be stationed outside. They will focus their sights on an escaping SCP-106 if the player has not yet contained it. They will activate the H.I.D. Turret to contain SCP-106, then go back to focusing their attention on the player if they haven't made their escape yet. If the Player already contained 106, the MTF will go straight for the player, taking them into custody.

If the player has captured SCP-106 but proceeds to go underground through the walkway in Gate A, the tunnel's entrance will be blocked off with a standard SCP Foundation door, with an MTF operative guarding it.

During the Gate B ending, SCP-682 breaks out of containment, forcing the Foundation to nuke the facility. If the player disabled the warheads, two MTF operatives (presumed to be from a different unit, Cloud Nine) will come through the blocked door and terminate the player. One will also randomly spawn outside of Gate B pathway to block D-9341's possible attempt of escaping the room.

Spoilers end here.

  • Nine-Tailed Fox members have various lines of dialogue that can be heard on the radio's fourth channel.
  • Their old in-game model is the same as the Guards. Aside from the Nine-Tailed Fox logo on their vests, the only real difference between the two is their body suits: the MTFs have black ones, while the Guards have white ones.
  • A new model is currently being developed for Epsilon-11.
  • The Nine-Tailed Fox is a popular creature in Asian mythology going by the name(s) of Jiǔwěihú, Kitsune Kyūbi, or Gumiho. It is believed to be a fox spirit that can change into a human in order to manipulate other humans.
  • Their old appearance closely resembles the French special forces, namely the GIGN, who wear the iconic yellow face shield, dark blue uniforms and kevlar vests similar to earlier versions of the GIGN in the game Counter-Strike.
  • It should also be mentioned that even with only 1 MTF operative approaching SCP-173, it will still not attack the soldier, even if they blink. If the player is not looking at it, the soldier will still be able to lock SCP-173 in the steel cage.
  • The quote "JÄVLA HELVETE Come out" is a mix of swedish swearing (JÄVLA HELVETE) and english (Come out). JÄVLA HELVETE when translated can mean "F***ING HELL".
  • MTF units have a large amount of health, however can die if they are attacked by SCPs like Zombies although it takes time.
