The Medal "For Distinction in Military Service" (Russian: Медаль «За отличие в воинской службе») was a military decoration awarded in two classes by the Soviet Union and later by the Russian Federation (until 1995), to deserving military personnel of the Ministry of Defense, of internal troops and of border troops of both the USSR and Russian Federation. It was gradually phased out following the dissolution of the USSR being replaced by various ministerial awards.
