"So always. The army thinks that we are the state security services, and the security services think that we are the army," complains the hero of the cult Soviet novel about military counterintelligence agents. In this sense, this is probably true. During World War II, special counterintelligence units of the NKVD and SMERSH fought the enemy on two fronts - an open front and a secret front belonging to the ranks of the Red Army. Counterintelligence veterans who saw the war with their own eyes have many memories. This book is a summary of their evidence and describes the other side of the war.
