Commandant's Service was the name for the military police of some Warsaw Pact^[1] and other armies. Its principal duties were providing garrison security and traffic control. It is not to be confused with a similar organization called Traffic Regulators operated by the Transport Troops of the Rear Services.

The Komendantskaya sluzhba (Russian: комендантская служба) or 'komendatura' (Ru:комендатура) in the Soviet and Russian militaries were designated by a red shield on one or both arms bearing a yellow letter "K", plain red shoulder boards and a white helmet bearing a red star and broad red circumferential stripe.^[2] These helmets were generally painted at the unit level ^[2][3] The komendatura have been replaced by the newly established Military Police (Ru:Военная полиция России or Voennaya politsiya or VP).

At one time the komendatura members wore a black cloth or leather uniform with white helmets and gloves, and belts and holsters.^[4][2][5][6]
