The minimum number of staff for any GRU undercover residency is two the resident and a combined radio/cipher officer. Such a theoretical minimum exists also for the other organisations, the KGB and the Ministry of Foreign Affairs. Theoretically the Soviet colony in a very small country may consist of six people, three of whom, the ambassador and two residents, are diplomats, and the other three radio/cipher officers. Each of the three branches of the Soviet colony has its own enciphering machine and completely independent channel of communication with Moscow. Equally, each has its own boss in Moscow the Minister of Foreign Affairs, the chairman of the KGB or the head of the GRU. Supreme arbitration between them can only be carried out in the Central Committee, which in its turn has an interest in fanning the flames of discord between the three organisations. The Central Committee has the right to recall any ambassador or resident and this same Central Committee has to decide questions as to which slots, and how many, should be accorded to each of the three organisations. This is a difficult task, as the Committee must not offend the KGB on questions of security, on the shadowing of its own diplomats above all, nor must it offend the GRU, for without the acquisition of data on present-day technology the quality of the Soviet Army would remain static. Finally it must not offend the 'clean ones'. They also must have a sufficient complement to serve as a screen for the dark activities of the two residencies.
This is why Soviet embassies, consulates, trade representations and so on grow and multiply and swell. As the residency grows, the resident acquires several deputies in place of the one he had at first. The number of radio/cipher officers increases. A technical services group is organised, an operational group, a tech-ops group, a radio monitoring station on the networks of the police and counter-intelligence. The number of operational officers engaged directly in recruiting and running agents increases. In the very biggest residencies of the GRU, such as that in New York, there may be from seventy to eighty officers. Medium-sized residencies like that in Rome would contain between thirty and forty officers. All officers on the staff of a residency are divided into three categories - operational staff, technical-operational staff and technical staff. The operational staff are those officers who are directly concerned with recruiting and running agents. In the operational staff are included residents, deputy residents and operational officers. To the technical-operations staff belong those officers who are directly concerned with and responsible for the production of intelligence, but who do not have personal contact with agents, nor often with foreigners at all. These are radio/cipher officers, officers of the technical services and operational technical services and the operators of the radio monitoring post. To the technical staff belong chauffeurs, guards and accountants.
The Resident
He is the senior representative of the GRU in any given place, and answerable only to the head of the GRU and the Central Committee. He is the boss of all GRU officers and has the right to send any of them, including his own deputies, out of the country immediately. In this case he does not even have to justify his decision, even in front of the head of the GRU and the Central Committee. The resident is completely responsible for security, both as regards the work of each of his individual officers and recruited agents, and the security of the residency as a whole. He is chosen from among the most experienced officers and as a rule must have a minimum of three to five years of successful work as an operational officer and three to five years as the deputy resident before his appointment. A resident in a large residency will hold the military rank of major-general, in medium and small residencies that of colonel. This does not mean that a lieutenant-colonel cannot be appointed resident, but then, according to the GRU system, he will be paid a full colonel's or major-general's salary and, if he copes successfully, will have to fill posts commensurate with the higher rank. He is not afterwards permitted to return to a post ordinarily filled by a lieutenant-colonel.
The deputy resident serves as the resident's assistant and assumes his responsibilities when he is absent. He undertakes the duties given to him by the resident and carries on recruiting work in the same way as all other operational officers. Frequently a deputy resident heads teams of officers working in one or another specialised field. Sometimes the resident himself supervises the most experienced operational officers and the deputy residents the younger, less experienced officers. In some very large residencies, and also sometimes where there is great activity on the part of GRU illegals, there is a post called deputy resident for illegals. The undercover residency and the illegal residency are completely separate and the undercover residency has no idea how many illegals there are, or where or how they work. At the same time, on instructions from the Centre, the undercover residency continually gives them help and support, placing money and passports in dead-letter boxes, emptying dead-letter boxes for them, studying conditions and clarifying certain important questions. Very often the undercover residency is used to rescue illegals.
The military rank of any deputy resident is full colonel. At the same time the same rules apply as apply to residents. The deputy resident may be a lieutenant-colonel or even a major; however, from the administrative and financial points of view he is a full colonel with full rights.
The Operational Officer
This is a GRU officer who carries out the recruitment of agents, runs them and through them receives or acquires the secret documents and samples of weaponry and military technology. Every operational officer from the moment of his arrival in the country is obliged to recruit a minimum of one agent, as well as often having to take charge of one or two other secret agents who have previously been recruited by his predecessors. He must keep these agents and increase their productivity. An identical burden is placed on the deputy resident at the same time as he is fulfilling the obligations of a deputy. This system is applied in all small residencies. In medium-sized residencies, the resident himself may take a direct interest in recruitment or not as he wishes. The residents of very large residencies are exempted from personal recruitment.
Alongside his recruitment work, the operational officer carries on with the acquisition of intelligence material by all possible means. He converses with foreigners, travels around the country and reads the press avidly. However, the GRU's over-riding view is that recruitment work is the most important part of an officer's duty, and it calls it number one (in addition to certain other colloquial words). All other work-support and the performing of operations for others, however important- is known as zero. One may be added to zero if a 'zero' agent manages to recruit a foreigner, in which case he becomes a '10', which is clearly the best number to be. For this reason an operational officer who has been abroad for three years and not recruited a single agent, even if he has achieved outstanding success in collecting the most interesting intelligence material, is considered to be idle. According to the standards of the GRU, he has sat for three years doing absolutely nothing and therefore hardly merits consideration for another overseas posting.
