Main Directorate of State Security

The Main Directorate of State Security (Glavnoe Upravlenie Gosudarstvennoi Bezopasnosti, Главное управление государственной безопасности, ГУГБ, GUGB) was the name of the Soviet intelligence service, secret police from July 1934 to April 1943. It was run under the auspices of the Peoples Commissariat of Internal Affairs (NKVD).

History

OO) of the GUGB-NKVD (responsible for counter-intelligence in the military) became part of the Army and Navy (RKKA and RKKF, respectively). The GUGB was removed from the NKVD and renamed Peoples Commissariat of State Security or NKGB. Following the outbreak of World War II, the NKVD and NKGB were reunited on July 20, 1941 and counter-intelligence was returned to the NKVD in January 1942. In April 1943 it was again transferred to the Narkomat of Defence and Narkomat of the Navy, becoming SMERSH (from Smert' Shpionam or "Death to Spies"); at the same time, the GUGB was again separated from the NKVD as NKGB.

GUGB Ranks
The GUGB had a unique system of ranks, a blend of position-rank system used in the army and personal ranks used in Militsiya; the rank insignia was also very distinct. Even though insignia introduced in 1937 followed the Red Army collar patch patterns, it assigned them very different ranks for GUGB and Internal Troops/political/specialist branches, with GUGB rank placed at least one grade higher than a similar army equivalent. .

When GUGB and Militsiya ranks were replaced with military ranks and insignia in February 1943, Major to Sergeant ranks were aligned with Colonel to Junior Lieutenant, and Senior Major and up were replaced with various degrees of Commissar. In 1945, General Commissar Lavrentiy Beria received the rank of the Marshal of the Soviet Union, and other GUGB Commissars received the ranks from Generals of the Army to Major General.
