Summary  
The document presents a classified study on Yuriy I. Nosenko, a KGB defector, detailing his alleged service within Soviet intelligence from 1962 to 1964, including roles in the Seventh Department of the KGB. It references interactions with other agents, internal KGB operations, and investigations into suspected double agents such as SLEESINGER, KOIEN, and ORMOLD. The text notes discrepancies in Nosenko’s accounts of his service, including conflicting claims about operational directives and recruitment activities. Redacted sections are present due to security concerns. A separate section discusses fragmented accounts of KGB operations during 1962–1964, referencing defectors like HOSEIKO, KOSEMOS, and NOSENKO, who provided inconsistent information about recall telegrams, operational directives, and interactions with the CIA. Disputes over the authenticity of a February 1964 recall telegram to an agent (HOSÉHKO) are noted, alongside evaluations of defectors’ credibility based on alignment with known records. KGB operations involving American tourists and internal conflicts within Soviet intelligence are also mentioned.
