The Union of Soviet Socialist Republics was the communist superpower that attempted to liberate Europe during Great World War II, Great World War III and the real World War III. While gaining the upper hand initially, it soon found itself outmaneuvered and eventually defeated in the three conflicts by the Allied Forces.
The Soviet Union is a communist nation, following Marxism-Leninism version of the communist ideology, calling for world communist revolution to be brought.
The Soviet Generals usualy use "strength in numbers" tactics to defeat their enemies, believing that assaulting with a large number of untrained units (Conscripts) and heavy tanks are the way to go.
After erasing Einstein, the Soviets broke the Iron Curtain and stormed Western Europe. Without Einstein, the Allies were on the run, but the Soviets unknowingly spawned a new, Pacific-native, technologically advanced, anime-influenced superpower: Japan, in the form of the Empire of the Rising Sun. So, the Japanese invaded the USSR from the east and the Soviets was forced to push them out of their Motherland in retaking Leningrad, Krasna-45 Launch Facility and Vladivostok and other cities, which were attacked by Japanese forces.
But in Western Europe, the Allied Forces, with the help of the USA, pushed back the Soviets behind the Iron Curtain in Eastern Europe, which remained under Soviet influence.
The Soviets have also assassinated Emperor Yoshiro at Mt. Fuji (see: Operation "To Tame a Living God" for more info) and an alliance was made between the Allies and the USSR against the Empire. The two factions together pushed back the Imperials from Europe back to Tokyo and reduced the Empire into ruins of its former glory.
After President Ackerman made a failed attempt to destroy Moscow and Soviet retaliation plans were discovered to strike undefended Allied cities using H-Bombs from Cuba, the alliance was off. The end result was the Siege of Leningrad in Operation: "The Moon Shall Never Have Them".
By the war's end, the once-mighty Soviet Union had been reduced to no more than an occupied state, split into 15 different republics. Premier Cherdenko and General Krukov were captured and, for committing crimes against all of mankind, sentenced to Cryo-Prison permanently.
But even with the strong presence of Allied occupational forces, not all Soviet forces surrendered. As the Uprising began in ernest, some formed a resistance movement under Dasha. The Soviet Underground's efforts and existence were officially ignored by the European Union which claimed the occupied territories were adapting enthusiastically to socio-economic changes.
The Underground proved more capable or resilient than the Allies expected. The Soviets struck at a number of Futuretech installations and discovered the development of the Sigma Harmonizer, which EU President Rupert Thornley plans to use it to wipe the Soviet Union off the face of the Earth and time. The Underground eventually discovered the Harmonizer's location on Sigma Island and destroyed it before it could become fully operational. Since the Underground exposed Futuretech's dark secret, the Allies deemed the Soviet Underground to be trustworthy and pulled out their occupational forces out of Russia as a sign of goodwill.

Battle vs. Global Defense Initiative (by STRiiK3R115)Edit
No battle written
WINNER: GLOBAL DEFENSE INITIATIVE
The GDI was victorious because its soldiers were used to fighting in limited numbers, whereas the Soviets were more used to attacking in massive numbers. The GDI has trained in more diverse environments than the Soviets, as well as packed more advanced and damaging weapons, which in the end brought them the win.
