# TOP SECRET615. B. Views of Intelligence Personnel1. Statement by DERYABINa. IntroductionFormer KGB officer Peter Sergeyevich DERYABIN has followed closely the entire course of CIA's investigation of NOSENKO and his information. He took part in the interrogations of NOSENKO in April 1964, January-February 1965, and October 1966 as an observer and consultant, and he personally questioned NOSENKO during July and August 1965 concerning certain aspects of his personal past and early KGB career. On the basis of his direct, personal knowledge of conditions within the Soviet Union and of KGB organization and procedures prior to his deſection in February 1954, supplemented by continuing study of later information from a variety of sources, DERYABIN is of the opinion that much of what NOSENKO has said about himself and the KGB is purposefully false or distorted. Although DERYABIN has been able to offer authoritative comment on many aspects of NOSENKO's story, the following section of this paper is limited to his remarks concerning HOSEN-KO's entry into the KGB (then MVD) and his Communist Party affiliation, both of which fall into the period when DERYABIN was active as a KGB (then MVD) staff officer. DERYABIN personally interrogated NOSENKO on these topics in the summer of 1965. Since DERYABIN was a personnel officer of the KGB (then MGB and MVD) in Moscow, with long experience in Communist Party activities, at the time NOSENKO claims to have entered the American Department of the KGB Second Chief Directorate, he is particularly qualified to comment on these aspects of NOSENKO's story.DERYABIN, as a Soviet Army officer, was graduated in 1945 from the higher counterintelligence school of Smersh (counter-intelligence with the Soviet Armed Forces). Following this he worked in Naval Smersh in Moscow and in March 1947 began to work in the MGB as a case officer in the Central Personnel Directorate. Shortly afterwards, when his superior was appointed Deputy Chief of the Chief Guards Directorate for Personnel, DERYABIN transferred with him to the Guards Directorate. He served as a Guards Directorate personnel officer until May 1952, rising through the ranks from case officer to the position of Chief of Section. One of his responsibilities was the approval of personnel for service in various units of the Guards Directorate, and he was also in charge of supervising personnel and security matters concerning one of the Directorate's surveillance sub-sections.After requesting a change from personnel to operational duties, DERYABIN was transferred in May 1952 to the Austro-German Department of the MGB Foreign Intelligence Directorate. Until December 1952 he served as the Deputy Chief of a sub-section in the Counterintelligence Sektor (desk) of the Austro-German Department. He was then appointed Deputy Chief of the intelligence Sektor of the same department, a position he held until March 1953. From March until September 1953, DERYABIN was the Deputy Chief of the section in MGB Headquarters which was responsible for the security of Soviets stationed in Austria and Germany. In September 1953 he was transferred to Vienna, where he became Deputy Chief of the section in the MVD Legal Residency responsible for the security of Soviets in Austria. He defected to American authorities on 15 February 1954.
