Russia is a faction in Shattered Union. It is unplayable in the campaign but playable in multiplayer. It is one of two non-American factions, the other being the European Union, and was already in existence long before the breakup of the USA and the start of the Second American Civil War. The Russian flag in "Shattered Union" is red, black, and white with a red star in one corner, instead of the red, blue and white with no red star of the real-life Russian Federation.
Some four weeks into the Second American Civil War, the Russian Federation annexes the former state of Alaska. Some resistance does occur, but whatever locals or former U.S. servicemen choose to resist are disorganized and on their own, making the invasion relatively unopposed. The invasion is personally led by President Nikolai Vladekov, a former Soviet Army general and hard-line communist, who is quoted as saying: "Alaska was never really part of the former U.S., and Russia is only taking back its former territory." The United Nations made no comment at the time.
Nikolai Vladekov is revealed 8 weeks into the war to have been engaged in black-market arms dealing for nearly 30 years when INTERPOL announces the results of its investigation into the nuclear bombing that destroyed Washington, D.C. The destruction of the USA's capital city, the deaths of millions of people in the blast (the majority of Congress and President Adams among them), and the chaotic spiral of events that led directly to the Second American Civil War are all found to be President Nikolai Vladekov's sole responsibility. He is reported by news network ZNN to have "masterminded the U.S. bombing to further his goal to disrupt the world economy, so that Russia could regain its military dominance and more easily control Europe". Compared to these things, Vladekov being under investigation for election tampering in Russia seems minor, but it is further evidence of his rampant personal and political corruption.
The invasion of Alaska and the news of Vladekov's corrupt actions are far from popular in Russia itself; massive protests in Russia force Vladekov to declare martial law in Moscow. Nonetheless, the Russian Federation remains in control of Alaska for however long it takes for the player's faction to re-unify the former 48 continental states, and has to be forced out of Alaska by the player's faction. The fight for Alaska is anticipated to be "one of the largest battles in recent memory" by ZNN, and its outcome has a significant effect on both the end of the Second American Civil War and on Russian politics. If the player's faction succeeds in Alaska, Russia loses control of Alaska and its occupation force there is routed with high casualties; it is possible for every Russian unit to be destroyed in the fighting, making the Russian defeat a total disaster. If the Russian occupation force is able to repulse the player's faction, Russia successfully annexes Alaska into the Russian Federation. Either outcome makes Vladekov either much less or much more popular in Russia.
"Recent revelations of election tampering by General Vladekov in Russia, were overshadowed by unrest in the former US. Vladekov successfully delayed further investigation by creating an emergency in Alaska using the expanded operations instituted by the EU as a catalyst. Vladekov's occupation of Alaska is not supported by the Russian Federation but the outcome in Alaska may trigger a major political shift for or against Vladekov depending on your outcome here in Alaska."
The Russian Federation has no association with the former United States or the European Union in terms of where it gets its military units. Every unit fielded by the Russians is Russian designed and made, although the Spetznaz (Commandos), Pioneers (Engineers), and single-use units are just unique-named versions of the same units. Russia almost always has only one unit in each class, and has no units classed as medium armor. The Russian single-use infantry unit is called "Sympathizers", indicating not all Alaskans and/or former U.S. servicemen were against the Russian occupation of Alaska. Russian units present in their sole appearance at the end of the campaign and available in multiplayer are light-gray or white in color, and are:
T-90, T-55, Hind, Bear, MiG-35 Interceptor, Smerch, BTR-90, Vodnik, RU Defense Tower, RU Bunker, Sympathizers, Spetznaz, Pioneers.
