Unlike in the first game, his team's deployment on centers around the fictional country of Adjikistan. They were sent to investigate a village held by Adjiki paramilitary wing soldiers after a UH-60 Black Hawk was shot down carrying a CIA personnel on board. Due to the lack of law enforcement in the country, they also had their assignments extended to anti-illegal drugs operations against a local drug cartel. As the game progresses, it is revealed that Adjikistan's President, Ismail Karim, is indeed corrupt and is using his powers and ties with European mercenaries to kill those who were against him prompting the U.S. to turn their back and support the rebel group in overthrowing the government.
