Ghost Recon Wiki

Sentinel Corporation Security Services, or Sentinel Corp. or Sentinel, is a private military company that appeared during the events of Tom Clancy's Ghost Recon Breakpoint.

Initially contracted by Skell Tech to augment its limited security force in response to Outcast attacks, the company eventually took over the island with assistance from Skell's former military adviser, Cole D. Walker. Enforcing martial law onto the populace, Sentinel began conducting experiments on the population and kidnapped military specialists in an effort to pursue the "Wonderland" project. However, their actions soon attracted the attention of the United States government, whom eventually deployed Ghost Recon units following the sinking of the USS Seay. This resulted in the crippling of Sentinel operations on the island as the Wonderland and CLAW projects were terminated owing to the surviving Ghost personnel.

Eventually, after attempting to launch a chemical attack on the United States, Sentinel CEO Trey Stone was killed by Ghost operator Nomad.


Founded by Trey Stone sometime after departing from the army, Sentinel expanded rapidly as Stone utilized his connections, eventually securing an abandoned Soviet military base in Kazakhstan. Recruiting former special forces soldiers globally, Sentinel soon expanded further, with Stone personally recruiting individuals such as Ilsa Herzog and Ian Blake into its ranks. By the 2020's, the company had conducted operations in nearly every single continent excluding North America.

Eventually, Leon Fairrow, with backing from his fellow conspirators approached Stone, contracting his company with Project CLAW. Readily accepting, Sentinel units began kidnapping military specialists. With the assistance of Senator Michael Lomax, Sentinel secured a wide variety of contracts from the United States military, operating in regions such as Africa and the Middle East during which they gained an infamous reputation for their brutality. Despite this, they were nevertheless effective in their operations.

In 2025, shortly after a devastating explosion at the Skell Foundation head office in the Auroa archipelago that resulted in the deaths of several employees, Skell Tech contracted Sentinel at the advice of their then military advisor, Cole D. Walker. Initially serving to augment the local security force and hunt down Outcast members, Sentinel began quietly amassing thousands of troops within the abandoned US military bases throughout the island. During this period, Fairrow and Stone began expanding Project CLAW, with Lomax and Fairrow both funneling massive amounts of funding to Sentinel as they began quietly expanding their reach island wide. Owing to their recommendation provided, Walker's Wolves and Sentinel forces began actively co-operating with each other, plotting to overthrow Skell and establish martial law on the island.

Accusing Skell of collaborating with the Outcasts, Sentinel forces launched a coup, forcing Jace Skell into hiding as he fled. Appointing Ayana Puri to head Skell, Stone and Walker began aggressively enforcing martial law throughout the island, including dissolving the island's parliament and limiting civilian movement. With discontent and anger brewing among the population, Sentinel forces began randomly detaining civilians, often conducting night-time raids against suspected Outcast sympathizers. This culminated in executions becoming commonplace, which largely succeeded in reining in further discontent.

Having secured the archipelago, Sentinel and the Wolves initiated a communications blackout. Owing to the sizeable R&D projects that the United States military contracted Skell Tech, the US Navy deployed the USS Seay, which mysteriously sunk off the coast of the island. Having been manipulated by Wonderland and Project CLAW conspirators, the President authorized the deployment of Ghost Recon to the island, in an effort to investigate and discover the cause of the sinking. Alerted well-ahead of their arrival, Sentinel forces began deploying drone swarms to patrol the perimeter.

As the USS Wasp arrived to the archipelago, the Ghost Recon platoon was ambushed by the drone swarm and subsequently slaughtered by Wolves investigating the crash sites. Despite eliminating a vast portion of the initial strike force, Ghost commander Nomad survived the crash, and reunited with several other survivors in Erewhon. Amongst the crash site survivors, Sentinel forces successfully captured Ghost operator Midas and forcibly inducted him into Project CLAW.

  • During the hours of darkness, Sentinel contractors will automatically turn on a flashlight on their left shoulder to help them see in the dark even though most manned locations on Aurora already have various light sources.
    • Despite this, contractors will utter voice lines in which they complain about the darkness hindering their ability to see.
  • Despite Skell Tech producing dedicated combat drones, Sentinel is attempting to weaponizing Skell's existing civilian models such as the Skell-Farmer and Skell-Pollinator, the latter of which was re-made into the fearsome Legion drone.
  • Certain voice lines uttered during combat indicate that Sentinel contractors receive a bonus payment in an unspecified currency for confirmed kills ("Bonus to whoever kills the bastard!"; "Go for the head, easiest way to make a couple of grand!"; "Twenty grand for his scalp!"; "Whoever ends this asshole gets a fat bonus!"). It is not clear whether these bonuses constitute a general policy or a policy that applies specifically to the surviving Ghost operators on Aurora.
  • In Operation Amber Ruin, Sentinel’s surviving Commanders in charge of the Gas deals wear a Blue Beret instead of a Red one
  • If they are moving around, there is a chance that you'll hear one say something like "Heads up we are Oscar Mike".
