For the first time in the history of the Russian state and the USSR, the veil of secrecy is removed from some aspects of military counterintelligence activities in the book. In a new perspective, portraits of famous military leaders and political figures are given. The author draws an extensive picture of a large historical period, of which he himself was a participant. It is a service in the GSVG, Transcaucasia and other regions. At the final stage of the service, he headed one of the faculties of the KGB Higher School, where he generously shared his combat experience.
