Describes training techniques used by the KGB in logistical preparation of their operatives for assignments abroad. This article focuses on the employment history of the KGB agent codenamed “Halef.” Between 1955 and 1967, Halef was stationed in Hong Kong and Tokyo. In 1967, due to his insignificant feedback and a weak performance as a field operative, Halef was transferred back as a trainer. As a trainer, Halef traveled extensively. While in the United States, the KGB developed a fictitious identity for Halef – a so-called legend-biography – in case his activity aroused suspicion and he were detained by authorities. In the United States, France and Mexico, Halef’s objectives included developing and testing means of communication with the KGB, which could be used to inform the KGB of an operative’s arrival to and departure from a country, request a meeting, or announce an emergency. In addition to assessing the existing signal language used among operatives, the KGB also instructed Halef to collect the data necessary to set up new surveillance locations in a number of countries. In 1977, Halef was performing assignments in Pakistan and Burma. In 1978, he and his wife were engaged in assignments throughout the USSR. From the USSR, they were relocated to the GDR and then to Bulgaria, where they boarded a cruise ship going from Varny to Suhumi to survey the ports of the Black Sea basin. Traveling through Odessa, Halef photographed military vessels and observed the procedures of the border patrol and customs officers.
