The Bolshevik Military and Battle Organizations (Russian: Военные и боевые организации большевиков) consisted of illegal armed formations ("revolutionaries") of Bolsheviks (RSDLP(b)) in the Russian Empire. They played a leading role among combat detachments of "working class" and revolutionary instigation in the Russian Armed Forces, with the goal of creation and fortification of the "Revolution Armed Forces".[1] Local committees of the Bolshevik Military Organization was also informally known as "Voyenka".[1]
The first military and battle organizations were created by Bolsheviks during the 1905 Russian Revolution in bigger cities of the Russian Empire: Saint Petersburg, Moscow, Ivanovo-Voznesensk, Kronshtadt, Sevastopol, Saratov, Krasnoyarsk, Nizhniy Novgorod, Tomsk, Warsaw, Vladivostok, Riga and others.[1] The statement of the 3rd Congress of the Russian Social Democratic Labour Party (25 April – 10 May, 1905), "About the armed uprising", had a significant meaning in the creation of military organization.

Officially, the Bolshevik Military Organizations were considered to be liquidated on decision of the 7th Congress of the Russian Communist Party (Bolsheviks)[1] in March of 1918.
