The Russian All-Military Union (in Russian Русский Обще-Воинский Союз, abbreviated РОВС, ROVS) is an organization that was founded by White Army General Pyotr Wrangel in the Kingdom of Serbs, Croats and Slovenes on September 1, 1924. This organization united all veterans of the Russian White movement, soldiers and officers alike, who were living abroad and desired to stay united for the purpose of purging Russia of the Bolshevik regime. The Union also tried to conduct operations within the USSR for the purpose of starting a national anti-communist uprising. The ROVS was formed outside of the Soviet Union.
Aside from anti-communism, the ROVS did not have an official political orientation, somewhat adhering to the old Russian military dictum: "The army is outside politics" (in Russian "Армия вне политики"), believing that the political orientation of Russia cannot be predetermined by émigrés living outside of its borders (the philosophy of "non-predetermination" or in Russian "непредрешенчество"). Many (but not all) of its members had monarchist sympathies but were divided on whether the House of Romanov should return and whether the government should be autocratic or democratic.
The ROVS, along with other similar Russian émigré organizations, became a prime target for the Soviet secret police, the OGPU. The OGPU even set up a fake anti-communist monarchist organization, the Monarchist Union of Central Russia, which was successfully used to confuse and later demoralize the ROVS. They also successfully instituted a secret provocational organization within the ROVS known as the "Inner Line" (in Russian "Внутренная Линия"), controlled by the double agent General Nikolai Skoblin, which masqueraded as a patriotic Russian intelligence organization.
