Original Item – Only One Available. This rare badge was issued to commemorate the 55th anniversary of the Officer Advanced Training Courses (KUOS) of the KGB USSR, an elite special-purpose training program created to prepare selected KGB officers for operational-combat missions during special periods. 

KUOS was created in 1966 as a special training program under the 1st Faculty of the Higher School of the KGB and was initially conducted as intensive five-month training assemblies. The program was led from its inception by major Khariton Ignatievich Bolotov, its first and only head, who played a decisive role in shaping its doctrine and training philosophy. In 1969, the courses were approved as a permanent structure within the Higher School of the KGB while remaining under the operational control of the First Chief Directorate (PGU), and full-scale operations began in Balashikha in mid-1970.

Each year, approximately sixty officers completed the demanding seven-month training program, which included advanced physical conditioning, firearms training, airborne and mountain operations, special tactics, demolitions, topography, intelligence activities, and the study of partisan warfare experience. Responsibility for preparing this special wartime reserve was assigned to the 8th Department of Directorate “S” (illegal intelligence) of the PGU KGB USSR. In June 1979, one KUOS class was graduated ahead of schedule, and on 5 July 1979 nearly the entire group was deployed to Afghanistan as part of a special task force Zenit, commanded by KUOS Colonel G. I. Boyarinov. The unit later expanded to approximately 150 personnel and participated in the operation that resulted in the elimination of Afghan leader Hafizullah Amin on 27 December 1979.

Badges associated with КUOS were issued strictly for internal presentation to graduates, instructors, and command staff, making this a scarce and historically significant artifact of Soviet state security training, highly sought after by advanced collectors of KGB and Russian intelligence memorabilia.
