Federation

The Federation is a fictional country which Downtown engages in combat with its forces in Antarctica.

Involvement
The Federation is first introduced in the first Antarctic mission, the Flashpoint, as they open fire on civilian tankers. Apparently, the Fed fleet had trouble controlling their admiral, who finally snapped, prompting the Federation to disavow the fleet. They had a base in Mt. Cerberus, which was destroyed by IC bombers.

Trivia
The Federation seems to be a carbon copy of Russia or its predecessor, the Soviet Union, as their pilots speak in a Russian accent and refers to their country as the "Motherland", simillar to the inhabitants of the Soviet Union, both countries use Soviet/Russian aircraft and ships, the flag includes a double-headed eagle like Russia's coat of arms, and the presentday Russia is indeed a federation.
