Main Intelligence Directorate (Russian:Главное разведывательное управление,romanized:Glavnoye razvedyvatel'noye upravleniye,IPA:[ˈglavnəjərɐzˈvʲɛdɨvətʲɪlʲnəjəʊprɐˈvlʲenʲɪjə]), abbreviatedGRU (Russian:ГРУ,IPA:[ɡɨ̞‿rɨ̞‿ˈu],[gru]), was the foreignmilitary intelligence agency of theGeneral Staff of the Soviet Armed Forces until 1991. For a few months it was also the foreign military intelligence agency of the newly establishedRussian Federation until 7 May 1992 when it was dissolved and theRussian GRU took over its activities.

The GRU's first predecessor in Russia formed on October 21, 1918 by secret order under the sponsorship ofLeon Trotsky (then the civilian leader of the Red Army), signed byJukums Vācietis, the firstcommander-in-chief of theRed Army (RKKA), and byEphraim Sklyansky, deputy to Trotsky;[1] it was originally known as the Registration Directorate (Registrupravlenie, or RU).Semyon Aralov was its first head. In his history of the early years of the GRU, Raymond W. Leonard writes:
As originally established, the Registration Department was not directly subordinate to the General Staff (at the time called the Red Army Field Staff –Polevoi Shtab). Administratively, it was the Third Department of the Field Staff's Operations Directorate. In July 1920, the RU was made the second of four main departments in the Operations Directorate. Until 1921, it was usually called theRegistrupr (Registration Department). That year, following theSoviet–Polish War, it was elevated in status to become the Second (Intelligence) Directorate of the Red Army Staff, and was thereafter known as theRazvedupr. This probably resulted from its new primary peacetime responsibilities as the main source of foreign intelligence for the Soviet leadership. As part of a major re-organization of the Red Army, sometime in 1925 or 1926 the RU (then Razvedyvatelnoe Upravlenye) became the Fourth (Intelligence) Directorate of the Red Army Staff, and was thereafter also known simply as the "Fourth Department." Throughout most of the interwar period, the men and women who worked for Red Army Intelligence called it either the Fourth Department, the Intelligence Service, theRazvedupr, or the RU. […] As a result of the re-organization [in 1926], carried out in part to break up Trotsky's hold on the army, the Fourth Department seems to have been placed directly under the control of theState Defense Council (Gosudarstvennaia komissiia oborony, or GKO), the successor of theRVSR. Thereafter its analysis and reports went directly to the GKO and thePolitburo, apparently even bypassing the Red Army Staff.[2]
The first head of the 4th Directorate wasYan Karlovich Berzin, a Latvian Communist and former member of theCheka, who served until 1935 and again in 1937. He was arrested in May 1938 and subsequently murdered in July 1938 during the so-called "Latvian Operation" ofJoseph Stalin'sGreat Purge.
The GRU in its modern form was created by Stalin in February 1942, less than a year after theinvasion of the Soviet Union by Nazi Germany. From April 1943 the GRU handled human intelligence exclusively outside the USSR.[3][4]
The GRU had the task of handling allmilitary intelligence, particularly the collection of intelligence of military or political significance from sources outside the Soviet Union. It operatedrezidenturas (residencies) all over the world, along with thesignals intelligence (SIGINT)station in Lourdes, Cuba, and throughout theSoviet-bloc countries.
The GRU was known in the Soviet government for its fierce independence from the rival "internal intelligence organizations", such as theMain Directorate of State Security (GUGB),State Political Directorate (GPU),MGB,OGPU,NKVD,NKGB,KGB and theFirst Chief Directorate (PGU). At the time of the GRU's creation, Lenin infuriated the Cheka (the predecessor of the KGB) by ordering it not to interfere with the GRU's operations.
Nonetheless, the Cheka infiltrated the GRU in 1919. That worsened a fierce rivalry between the two agencies, which were both engaged in espionage. The rivalry became even more intense than that between theFederal Bureau of Investigation andCentral Intelligence Agency in the US.
The existence of the GRU was not publicized during the Soviet era, but documents concerning it became available in the West in the late 1920s, and it was mentioned in the 1931 memoirs of the first OGPU defector,Georges Agabekov, and described in detail in the 1939 autobiography ofWalter Krivitsky (I Was Stalin's Agent), who was the most senior Red Army intelligence officer ever to defect.[5] It became widely known in Russia, and in the West outside the narrow confines of theintelligence community, duringperestroika, in part thanks to the writings of "Viktor Suvorov" (Vladimir Rezun), a GRU officer who defected to Great Britain in 1978 and wrote about his experiences in the Soviet military and intelligence services. According to Suvorov, even theGeneral Secretary of the Communist Party of the Soviet Union, when entering the GRU headquarters, needed to go through a security screening. InAquarium Suvorov alleges that during his training and service he was often reminded that exiting the GRU (retiring) was only possible through "The Smoke Stack". This was a GRU reference to a training film shown to him, in which he alleges he watched a condemned agent being burned alive in a furnace.,[6][page needed]
During theCold War, the Sixth Directorate was responsible for monitoringIntelsatcommunication satellites traffic.[7]
GRU Sixth Directorate officers reportedly visitedNorth Korea following the capture (January 1968) of theUSSPueblo, inspecting the vessel and receiving some of the captured equipment.[8]

Other collateral sources reported that a group of Soviet military intelligence officers from the Sixth Directorate (responsible for Soviet SIGINT matters) of the Chief Intelligence Directorate (GRU) visited North Korea shortly after the seizure of the ship and inspected the vessel. Later, the North Koreans were reported to have turned over some of the captured equipment to the GRU. Apparently, some of this equipment was taken to Soviet radio plants in Kharkov, Voronezh, and Gorkij for examination by technicians.
