Col. Vladimir Makarovich Izmaylov was a Soviet national serving as an Air Force attache at the Russian Embassy, who in the mid-1980's attempted to recruit an Air Force officer assigned to the National Capital Region as a spy. The officer reported this activity to the FBI and OSI, and both agencies agreed he should accept Izmaylov's offer in order to act as a double spy and uncover Soviet spy methods and build a case against Izmaylov. After more than a year collecting information, there was enough evidence for the U.S. to expel Izmaylov from the country in 1986.
