Peace Sentinel

The Peace Sentinels were a rogue unit within the CIA formed by the CIA Station Chief of Central America Hot Coldman. Their goal was to create a perfect Nuclear Deterrant through the Peace Walker Project.

Peace Walker
While in exile in Central America in order to keep him from leaking out to citizens the true reason behind Operation Snake Eater, Coldman decided that the only things capable of doing anything without fail are machines, and decided to create a new order involving machines ruling over Humanity. He decided the first place to start was to create the perfect deterrant. He then formed the Peace Sentinels to help achieve this goal. He also formed an alliance with KGB agent Vladimir Zadornov to supply the Peace Sentinels with several of their equipment and additional manpower in exchange for giving them land and money. Dr. Huey Emmerich and Strangelove were also recruited into the Peace Sentinels in order to develop the key components of the Peace Walker Project (the AI weapons, including the final model Basilisk, and the Mammal Pod).

The Peace Sentinels then captured a FSLN owned drug-purification plant (disguised as Banana and Coffee factories), forcing the FSLN group led by Amanda Valenciano Libre to hide in the last remaining hideout: the boathouse. During this time, they also captured several FSLN members in Costa Rica, tortured them to reveal their comrades locations, and then kill them as soon as they reveal where they went. It was also implied that the Peace Sentinels started using both the routes belonging to the FSLN and the drug refining plants they captured to ship drugs to America. after they captured them. The Peace Sentinels finally arranged for Mercenaries to arrive in Costa Rica, and also had Nuclear Warheads delivered to Costa Rica. They also set up various bases in 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 Costa Rica and Nicaragua. They also turned a peaceful village, Aldea de los Despiertos, into a prison facility against the villagers will.

The Peace Sentinels later captured a French Ornithologist named Cécile Cosina Caminades after she accidentally stumbled upon the Mammal Pod's AI impersonation of The Boss in the AI Facility while recording and watching sounds for the Quetzal. Paz Ortega Andrade, working for Cipher, uses this recording as a bargaining chip to infiltrate MSF and eventually attempt to convince Big Boss to join Cipher.

Stabbing his "ally" in the back, Vladimir (under the alias of the United Nations University of Peace professor Ramón Gálvez Mena) requested for the Militaires Sans Frontieres to get them out of Costa Rica, as well as to investigate what their activities are. The Peace Sentinels then are dealing with the Militaires Sans Frontieres and their attempts to stop their project. Coldman eventually captures Big Boss after he tries to talk with The Boss's AI, and reveals his plans. After Peace Walker was completed, he then relocated the Peace Walker unit to an American Missile Base in Nicaragua.

The Peace Sentinel's so-called soviet allies then turn on them as Vladimir reveals his betrayal and changes the previous false data setting, the Mother Base, for Peace Walker to launch at Cuba. Unfortunately, Coldman, after succumbing to bloodloss from the gunshot wound that Vladimir inflicted upon him, activated Peace Walker and nearly caused a Nuclear Catastrophe. What became of the Peace Sentinels after the events of project Peace Walker is unknown, although they may have been disbanded.
