The Kremlin is the official residence of Soviet Premier Alexander Romanov. Throughout the Third Great War the Kremlin acts as the headquarters of Romanov and the Soviet military High Command, and it is here that the most important political and military decisions by the Russians are taken during the war. Subsequently, during the second annual victory parade celebrating the Russian victory in the war, Epsilon forces attack Moscow, capture the Kremlin and build a Psychic Beacon next to it to control the city.
- The Kremlin appears in the center of the map in The Conqueror, protected by several defenders from the Black Guard. Romanov flees to the Kremlin's grounds while awaiting a Borillo for evacuation, but he is killed by Epsilon soldiers sent after him by Yuri's Proselyte during the Epsilon takeover of Moscow, after which a Psychic Beacon is built next to the Kremlin allowing Yuri to take control of the entire city. Yuri himself then enters the Kremlin, inviting the Proselyte to celebrate in his new office.
- The name "Kremlin" means "fortress inside a city" in Russian, and the Kremlin of Moscow is technically one of many fortified structures bearing the same name, although the one in Moscow is unquestionably the best known of them all, so much so that the name "Kremlin" is often used metonymically to refer to the government of Russia, as is the case in the Mental Omega briefings as well.
