Prior to Revvoyensoviet, the two main military authorities had been the Supreme Military Council (Высший военный совет, Vysshy voyenny sovyet) and the operations division of the People's Commissariat on War and Navy Affairs.
The decree put all fronts and military organizations under the command of the chairman of Revvoyensoviet, with a commander-in-chief second-in-line to the chairman to lead strategic and military operations stateside. The chairman was appointed by VTsIK on to serve as People's Commissar (or narkom) of War and Navy Affairs.
On November 30, 1918, the Council of Labour and Defense was created with the goal of mobilizing the country's resources towards defense. Headed by Lenin, the council consisted of the premier (Lenin), the chairman of Revvoyensoviet (Trotsky), a representative of VTsIK (Joseph Stalin), and several narkoms.
Revvoyensoviet was dissolved under the Soviet Union in 1934.
