Anything related to the former Soviet Union, and, to a wider extent, the Warsaw Pact.
The Soviet Union (1917-1991), officially the Union of Soviet Socialist Republics (USSR), was a vast communist federated state in what is today Russia and other adjacent nations with a state ideology of Marxism-Leninism. The Warsaw Pact was a collective defense treaty created in response to the expansion NATO, led largely in the foreign policy interests of the Soviet Union, including the remaining communist states in Europe of the era, sans Yugoslavia and, later, Albania, with key world allies such as Marxist-Leninist Cuba, although the tag should not apply to states that did not constitute the Soviet Union.
This tag can refer to a) Soviet-related iconography, such as the Hammer and Sickle, Red Star, Soviet-stylized Cyrillic, Russian, or other text; or b) posts that either show a location within the Soviet Union during the period of its existence, or are indicated as being of the general era when the Soviet Union or Warsaw Pact existed (based on architecture, attire, technology, etc.), in which case the post would be tagged with this tag and the respective country tag (if one applies), e.g., like soviet russia or soviet ukraine.
