Rezidentura

   The Russian word for intelligence station is rezidentura (residency). Both the KGB and the GRU used the term. KGB rezidenturas were compartmentalized into “lines.” Line PR (Political Intelligence) was responsible for the collection of political and economic intelligence and active measures. Line KR (Counterintelligence) was responsible for the protection of the Russian diplomatic colony and for penetration of hostile intelligence and security services. Many Line KR officers began their career in the domestic counterintelligence components of the KGB. Line X (Scientific and Technical Intelligence) recruited and ran agents with access to scientific and commercial information.

   Line N (Illegal Support) supported the operation of illegals. It recruited agents with access to official documents and archives necessary for the identity of illegals. Line N officers also maintained contact with illegals through indirect means of communication such as dead drops.

   KGB and GRU rezidenturas had large support staffs, including dedicated code clerks. Rezidenturas also conducted signal intelligence operations from embassies, consulates, and the personal residences of diplomats.
