'''Soviet Border Troops''', ({{lang-ru|Пограничные войска СССР|Pogranichnyie voiska SSSR}}) were the [[military|militarized]] [[border guard]] of the [[Soviet Union]], subordinated to its subsequently reorganized [[Secret police|state security]] agency: first to ''[[Cheka]]''/[[State Political Directorate|OGPU]], then to [[NKVD]]/[[Ministry of Internal Affairs (Soviet Union)|MVD]]/[[Ministry for State Security (USSR)|MGB]] and, finally, to [[KGB]]. Accordingly, they were known as '''NKVD Border Troops''' and '''KGB Border Troops''' (with [[Russian language|Russian]] abbreviations - ''НКВД СССР'' or - ''КГБ СССР'' added on the end of official names). Unlike border guards of many other countries, Soviet Border Troops were a centralized force including also the marine units of the Border Troops (i.e., a [[coast guard]]).
