Despite being subordinated to a civilian police authority, Internal Troops are a military force with centralized system of ranks, command and service. The chief commander and staff of the Troops report only to the Ministry of Internal Affairs, maintaining their separate chain of command. Soviet VV units were predominantly formed up of conscripts drafted by the same system as for the Soviet Army. Modern troops in Russia and Ukraine are experiencing a slow transition to the contract personnel system. VV officers are trained in both own special academies and the Army's military academies.
