United States Missile Base (Nicaragua)

The U.S. Missile Base is a base located in Nicaragua, near the southeastern shore of Lake Nicaragua. It is a Missile/Military Supply Base owned by the United States of America and stationed in Nicaragua. It has a communications tower, a heliport, a maintenance dock, a runway, and a security monitoring room.

Operation Peace Walker
During the Peace Walker project, Coldman, the leader of the Peace Sentinels, formed an alliance with a KGB Unit led by Vladimir Zadornov where he got Soviet Technology in exchange for giving the Soviets money and land. Because of this, the United States Missile Base had several Soviet Soldiers stationed at the area. Coldman later returned to the Missile Base with Peace Walker, now fully functional, in tow. Snake, who had earlier failed to stop Peace Walker especially with the death of The Boss's Horse, had snuck into the Missile/Supply Base's back entrance by disguising himself as cargo for a passing truck. After briefly talking with Kaz about the situation at Mother Base (which was to be targeted by Peace Walker), he then proceeded to go towards the communications tower, as that was where Coldman was to conduct his final test for Peace Walker. Along the way, he noticed that Soviet soldiers were stationed in the base, which didn't seem right at all. After sneaking by several Soviet soldiers and Kidnapper drones, Snake managed to arrive at a security monitor room and located Paz, as well as learning that Coldman went to the control tower to input the final data for the test. However, an alarm system went off shortly after she reveals this, indicated that the Soviets now know that Snake is on the Base. Luckily, the MSF was coming in the form of a large military force to aid Snake. Snake then had to battle his way back to the Small Maintenance Dock and all the way to the underpass until he reached the elevator. However, the guards also came prepared in the form of a Hind D Attack Chopper and a platoon near the Heliport. After shooting down the Hind D and dispatching the platoon, the blast doors to the Communications tower opened allowing for Snake to enter after defeating the reinforcements. Snake then encountered Coldman at the top floor of the Communications Tower. Coldman then revealed that not only was the data already set in place, but the data was actually false data used to trick Peace Walker into launching a nuke towards Mother Base, as it can't launch a nuke by itself pre-emptively due to it being a deterrent. However, he was betrayed Zadornov and his KGB unit, and changed the target to Cuba to make it seem as though America would launch the weapon at Cuba, one of the Soviet Union's biggest allies by the international committee, which would consequently cause Communism to spread throughout Latin America unchecked, and thus win the Cold War. Zadornov then forced Paz to shoot Coldman in the chest, deliberately avoiding the killing shot due to wanting Coldman to finish inputting the code, and then threatening Strangelove to change the target to Cuba. He then decided to execute Big Boss as he no longer had a use to him, as well as inspire more rebellions, wanting to repeat Che Guevara's death. However, he was stopped by the MSF and, ironically enough, the FSLN, the group that the KGB backed to further their goal. Snake stayed behind to "bury the Mammal Pod," although he then decided to go with Strangelove to find out the truth. However, they didn't get to Peace Walker before Coldman, while dying, activated Peace Walker, which not only caused it to target Cuba due to the false data, but also caused the Mammal Pod to transmit the same false data to NORAD, nearly causing a Nuclear War. Snake and Strangelove were then forced to destroy Peace Walker to prevent a nuclear threat, as Coldman died without revealing the Abort Code (as he intended to activated it on his death bed, knowing full well that he'll die before he could mention the abort code.). Although preventing the Nuclear Launch, the Mammal Pod was still transmitting the False Data. Even after removing all of the drives, it still didn't stop the transmission, and it only took The Boss possessing Peace Walker to sacrifice itself by drowning in Lake Nicaragua to end it. What became of the United States Missile Base after this is unknown.
