Colonel Arkady Kirilenko (Russian: Аркадий Кириленко) is the main antagonist in Battlefield: Bad Company 2.
Kirilenko is a Russian Colonel and scientist that seeks the destruction of the United States of America. He is under the protection of the Russian Elite Forces and commands the local Militia to protect him.
Bravo-Two Charlie first encounters him at the start of the mission Cold War, where he executes a US soldier that Bad Company was supposed to rescue. Preston Marlowe had Kirilenko in his sights, but was not given authorization to shoot him.Later on, while speaking with Agent Aguire, Bravo-Two Charlie finds out that Kirilenko is searching for the "Black Weapon," a Japanese-designed weapon of mass destruction constructed during World War II. The squad is then sent to Chile to find the compound and Kirilenko. With help from the U.S. 1 Armored Division, they eventually find him by information given by a Russian prisoner, but Kirilenko manages to escape when the building he is in starts to be bombarded, which momentarily distracted Bravo Two long enough for him to escape.
The squad finds the compound in the old freighter, the Sangre Del Toro, and gives it to Aguire, who then double-crosses them and gives it to Kirilenko. Kirilenko then betrays Aguire and kills him, before ordering his troops to kill the members of Bad Company. However, after the timely arrival of Flynn's UH-60 Black Hawk which kills most of his troops, Kirilenko orders a soldier with an RPG to fire at him, downing the helicopter and causing it to explode, much to the squad's dismay.
Bad Company then move through a South American city to find Kirilenko and the "Scalar Weapon", the Weapon of Mass Destruction for which the compound was required, but as they find the scalar weapon, it is test fired, wiping out a large US Force inside the city. 'B' Company follows and boards the plane which Kirilenko and the scalar weapon are on. The plane takes off for the US to deliver the scalar weapon's deadly punch, but over the state of Texas, Marlowe destroyed the scalar weapon, which tore apart the plane and putting them and Kirilenko into a free fall.
