Peace Sentinel

The Peace Sentinels were a rogue unit within the CIA that was formed by Station Chief of Central America Hot Coldman during the early 1970s.

Origins
After being demoted from his previous position as DCI in 1964 and was exiled to Central America under the guise of becoming the Station Chief of Central America, an embittered Coldman decided to act out his belief that only machines could make decisions and act on them without fail and decided to create "a new world order", in which machines would rule over Humanity via "the perfect nuclear deterrant".

After 1972, Coldman founded the Peace Sentinels to help achieve this goal, forming an alliance with KGB agent Vladimir Zadornov to supply the group with equipment and additional manpower, in exchange for providing them land and money. He then recruited Doctors Huey Emmerich and Strangelove into the Peace Sentinels in order to develop the key components of the Peace Walker Project: Huey developed the outer frames of the models (Pupa, Chrysalis, Cocoon, and Peace Walker) and Strangelove developed the respective AI Pods for the models (GW-Pupa-5000, TJ-Chrysalis-6000, and TR-Cocoon-7000) and Peace Walker's Reptile Pod (AL-Aurelia-8000) and Mammal Pod (The Boss's AI).

Around 1973, the Peace Sentinels started covertly invading Costa Rica and also disguised their activities as acting as members of CODESA.

In 1974, the Peace Sentinels captured an FSLN-owned drug-purification plant in Costa Rica (disguised as a factory for banana and coffee), forcing the FSLN guerillas (led by Amanda Valenciano Libre) to retreat to their last remaining hideout in a boathouse. Several FSLN members were captured and interrogated on the whereabouts of their comrades, before being killed after giving up said information. The Peace Sentinels then made use of the drug smuggling routes that had belonged to the FSLN, and the refining plants they had captured, to ship drugs into the United States. Afterwards, the Peace Sentinels set up various bases throughout Costa Rica, including the facility in Mount Irazu, the AI facility in a Mayan pyramid, and the production facility underneath a mining facility, located near the border of Nicaragua. The Peace Sentinels also hired mercenaries to operate in the country and shipped in nuclear warheads. The formerly peaceful village of Aldea de los Despiertos was turned into a prison facility against the villagers' will.

The Peace Sentinels later captured French ornithologist Cécile Cosina Caminades, who had accidentally stumbled upon and recorded The Boss's AI while studying the native Quetzal. Afterwards, Zadornov (assuming the identity of Professor Ramón Gálvez Mena of the United Nation's University for Peace) and Paz Ortega Andrade used the tape recording as a bargaining chip for hiring the Militaires Sans Frontieres, convincing Big Boss (Naked Snake) and Kazuhira Miller to assist in the liberation of Costa Rica from the invading army.

The Peace Sentinels were then forced to deal with the MSF, and their attempts to stop their project. Coldman eventually captured Big Boss, after the latter attempted to speak with The Boss's AI. Coldman had Big Boss interrogated for information necessary for the AI's completion, after which he relocated Peace Walker to a U.S. missile base in Nicaragua.

However, the Peace Sentinels' so-called Soviet allies later betrayed them as Zadornov intended for Peace Walker to launch a nuclear strike at Cuba, in a plan to foment anti-American sentiment across Latin America. After being stopped by Amanda's FSLN guerillas' timely arrival and MSF's arresting of the Peace Sentinels, Coldman (who was close to death thanks to Zadornov's earlier gunshot) chose to activate Peace Walker anyway (despite its change in target) and MSF were able to destroy the weapon before it could launch and its transfer of false trajectory data to NORAD was subsequently halted, preventing the potential outbreak of a nuclear war. A short while later, some of the Peace Sentinels (likely hired by Zadornov) would remain on patrol in Costa Rica for sometime afterwards.

The Peace Sentinel members were also planned to be executed by Hot Coldman after the tests were completed.

Soldier Types
There were several types of soldiers within the Peace Sentinels that were encountered by the MSF unit and the FSLN group.

Patrolmen/Guards
The most common soldier within the Peace Sentinels are the soldiers that patrol or guard a specific operational area. They are referred to as Patrolmen for the outdoor areas and Guards for the indoor areas. Their senses are also finely honed so as to ensure that they do their job, and they also assume a more efficient alert posture if an alert is triggered. Their attire is also somewhat different depending on their specific duties. Patrolmen wear green jackets shirts, jackets, a utility belt, green pants, balaclavas, and (sometimes) a battle helmet. The guards wear a bit more bland clothing, which consists of a white shirt, green pants, and a gun holster. The latter are also one of the few types of soldiers whose faces are exposed. Sometimes they also wear headsets or shades. The Guards also sometimes wear vests and even helmets.

Commandos
These types of soldiers are an assault team that are often deployed if an Alert is raised. Well trained, heavily armed, as well as highly dangerous, these soldiers are relentless in regards to hunting down intruders, which involves searching every possible square area, even likely hiding places until they either find the intruder or the alert is called off completely. The Commandos also utilize body armor, meaning that a direct assault would be unadvisable against them. Commandos also tend to wear helmets and two-eyed balaclavas, and sport navy blue-black outfits, bulked up due to the body armor.

Shock Troops
A subset of the Commandos, these soldiers utilize shotguns as their primary firearm, and have an endurance level that can allow them to take a few hits and still keep charging at the enemy and firing shotguns. Their uniforms are primarily gray with green utility straps, and wear "t" balaclavas that are adorned with headsets and, should the situation arise, night-vision goggles.

Scouts
Soldiers that are specialized in ambushes. They wear primarily green clothing, in order to blend themselves in with the terrain and the vegetation. They only expose themselves when about to attack. Their fighting style is similar to the Commandos, including the use of clearing techniques to flush intruders out. Aside from normal weapons, the scouts also carry wires in case the intruder they are dealing with knows CQC, making CQC-related attacks on them heavily unadvisable if caught.

Ghillie Suit Soldiers
A subset of Scouts, these soldiers take their camouflage to the next level, where they utilize ghillie suits. However, their combat ability is not much different than the Scouts. Their primarily ability is presumably as Snipers, given the fact that they lie completely still and that they are using sniper rifles.

Sentries
Soldiers that are deployed in several layers such as watchtowers. These soldiers can attack from a distance such as rooftops and far-off vantage points. Also, their high distance also makes it extremely difficult for fultoning them to work, unless a specialized launcher is used.

Escorts
Also referred to as reinforced soldiers, these soldiers accompany Armored Vehicles, Tanks, and Helicopters when on operations. The soldiers themselves are not difficult on their own, but they are formidable in the sense that they know how to operate as a team, meaning that they have a tendency to gang up on any enemy soldiers that are spotted. The soldiers also often give commands to each other when on duty, which, if the enemy listens in, can give the enemy an advantage to winning against them if they know what they say. The escorts often wear reinforced armor, as well as white helmets adorning the Peace Sentinel logo, as well as wearing a face mask that is very similar to a gas mask. Original escort units carry M653's however when they are neutralised, extra escort units arrive as back-up and may carry different weapons. The most intense battles may allow up to 36 escorts, although only up to four at a time can appear.

In Main Ops only a small number can be allowed and carry basic small arms such as the M653 or M10 however in further extra ops they arrive in greater numbers, carrying different weapons, even more powerful weapons such as light machine guns, rocket-propelled grenades or even shotguns making them even more difficult to defeat.

Escorts are known to carry the following weapons: LAW, M10, M60, M653, PKM, RPG-7, SPAS-12 and the FAL. They also carry knives, as they seem to stab the intruder if in close quarters.

Commanders/Captains
The presumed leaders of the Armored Vehicle, Tank, and Helicopter units, these soldiers pilot the vehicles in question. The only notable difference in appearance from other escorts is that these soldiers adorn red helmets instead of white helmets. These soldiers don't pop out to fight until their entire unit has been neutralized. In the case of Helicopter units, the captains can also be exposed if the cockpit is blown off by bulletfire. For unknown reasons, the captains have a tendency to put their own comrades lives at risk by firing missiles around their comrades perimeter even when the intruder hadn't even been caught yet. Sometimes they will toss a grenade at players when exposed.

Shield Soldiers
These soldiers don't belong to a specific unit, but they are still formidable as they carry riot shields when attacking their enemies. They are susceptible at the legs or from armor piercing rounds, and can be blinded with flash or smoke grenades.

CIA Mercenaries
Although this name applies to the entirety of the Peace Sentinels, this is more referring to the type of soldier that wears orange jackets, olive pants, Military ball caps, and carrying assault rifles. These soldiers were primarily stationed around the del Alba area, guarding the Shipping Facility, although one soldier was stationed in Central Heredia, where he stole the ID card that Cécile Caminades swiped to escape from the AI Laboratory.

KGB Soldiers
Although not loyal followers of the Peace Sentinels, several of these Soviet soldiers were provided to the Peace Sentinels as additional manpower due to the alliance between Coldman and Zadornov. These soldiers wore brown pants, black boots, beige shirts (similar to office shirts) with a red tie and a red communist armband on the left arm, body armor, as well as a bulletproof helmet with a visor similar to the Battle Dress w/Helmet armor or Riot helmets. Underneath the helmets they wear two-eyed balaclavas. While the exact portion of the Soviet military that they serve is never actually specified, the fact that they were under Zadornov's command suggests that they serve the KGB.
