That these 'walk-ins' are an extremely unpredictable form of recruitment is perhaps best illustrated by two examples, both of which occurred at the same residency in West Germany. An American sergeant came to one of the Soviet observation missions in West Germany (each of which is a GRU residency), bringing with him the block of a cipher machine used in one of the American bases. The sergeant announced that for a certain sum he could bring a second part of the machine and added that there could only be a deal on condition that the GRU would not subsequently attempt to recruit him. The residency immediately accepted both proposals. The sergeant got his money and an assurance that the GRU would forget all about him immediately after the deal was done.
The cipher machine which was obtained, or more accurately two of its basic blocks, enabled the technical services of the GRU to decipher thousands of American radio communications which had been intercepted earlier but remained undeciphered. They also enabled them to study the principles of cipher work in the American Army and in the armies of its allies and, by exploiting the American principles, to create more complete Soviet examples. What about the sergeant? Of course he was immediately recruited....
On another occasion a couple of years later an American major approached the same Soviet residency proposing to sell an American atomic artillery shell. In proof of his good intentions he handed over free of charge to the residency detailed plans of the atomic depots and instructions on checking procedures and standing orders for work with atomic equipment. These documents by themselves were of great value, although the major's main proposal was of vastly greater interest. The major announced that he would demand a substantial sum for the shell, and imposed the condition that the Soviet side, having studied the shell, must return it after two months. Some days later, the specialists of the GRU information service confirmed the genuineness and very great importance of the documents which had been acquired. The GRU leadership decided to buy the atomic shell and to pay the price demanded for it by the American. A number of the senior officers of the residency were called to Moscow and given a crash course in American atomic technology. A week later, on a dark rainy night in a clearing in the middle of a forest, two motor cars met. In one was the American major, in the other three operational officers. There were two more Soviet cars hidden nearby, ready to intervene if necessary. Many people did without sleep that night. The Soviet Consul dozed by his telephone, in full readiness to come tearing out to the wood and in the name of the Union of Soviet Socialist Republics to defend the military diplomats. On the orders of the Central Committee, many highly placed officials in the Ministry of Foreign Affairs and Tass were also on alert. Of course they did not know what was going on or where, but they were ready to announce to the world that the imperialists had mounted yet another provocation against the Soviet Union. In fact, the Tass and Ministry of Foreign Affairs announcements were already prepared. But everything went according to plan. The American and the three Soviets transferred the shell from one car to the other, and a thorough check was carried out. The operational officers knew beforehand the serial number, the level of radiation, the exact weight and the markings which would identify it as a genuine shell. All was as it should be. The Soviets handed over a briefcase full of banknotes to the American and agreed to meet in two months' time for the return of the shell. Once the shell was in the Soviet car with diplomatic number plates, it was tantamount to being on Soviet territory. The police could stop the car, but they did not have the right to search it nor remove anything from it. Diplomatic immunity is not to be trifled with. In the event nobody stopped the officers, and the car drove peacefully into the courtyard of the Soviet diplomatic mission. Later the shell was transported in a diplomatic container under armed guard to the Soviet Union.
The GRU chief joyfully informed the Central Committee of the successful outcome of the operation. 'Where is the bomb?' asked a voice on the telephone. 'We have it in GRU headquarters.' 'In Moscow!?' 'Yes.'
A long and largely unprintable tirade ensued, whose import was roughly as follows: 'And what happens if there is a little spring inside this shell and it explodes right in the middle of the Soviet capital and turns Moscow into Hiroshima?'
The GRU had worked out the whole operation with the maximum number of precautionary measures and the plan to acquire the shell had been confirmed by all departments from the chief to the general staff up to the Central Committee. However, nobody had foreseen the possibility that there could be a timed device in the shell and that the Central Committee, the Politburo, the KGB, the GRU, all the Ministers and departments of State, the general staff, all the Military Academies, all the principal design bureaux, in a word, everything which constitutes Soviet power, could be instantaneously destroyed. There was no answer. No defence was possible. One shell and the whole system could have gone up, because everybody and everything is controlled from Moscow. The possibility of such an occurrence had only been realised in the Central Committee when the shell was already in Moscow. Instead of the expected decoration, the GRU chief received a 'service incompetence note' - a strong warning that in the future even the most trivial mistake would lead to dismissal.
The shell was taken for the time being to the central aerodrome and a military transport aircraft speedily transported it to Novaya Zemlya. The shell did not explode. At the same time there was no guarantee that it would not explode while it was being dismantled and destroy the leading Soviet specialists who were working on it, so the dismantling was conducted in a special pavilion hurriedly constructed on the atomic testing ground. Preliminary work on the shell had already disquieted the Soviet specialists, as it was much more radioactive than it should have been. After protracted arguments and consultations, the shell was dismantled with the greatest possible care. Only then was it found that it was not a shell at all - but a beautifully executed copy.
The American major from the depot for atomic armaments had known to the last detail how to do this. He had taken a written-off practice shell or, as it is called, a 'standard weight equivalent', had painted it as a real shell and put on a corresponding marking and number. Inside the shell he had put some radioactive waste which he had obtained. Of course he was not able to regulate this to the extent that the level of radiation would conform to the level of radiation of a genuine shell, but this was not necessary. At the time when it was first checked after having been handed over to the operational officers, there had been no attempt to determine the exact level of radioactivity. The officers had only been interested to see whether there was radiation or not. After all that had happened the officers who had taken part in the operation, of course, received no decorations but at the same time they were not punished and neither was the GRU chief. The Special Commission of the General Staff and Central Committee established that the forgery had been very skilfully and thoroughly executed and that there had been little possibility of exposing it at the time of the hand-over. All the same the GRU was not happy about it. It began a search for the American major. The first attempts proved unsuccessful. It was established that he had been posted to the USA immediately after the sale of the forgery, and it would not be so easy to find him there. He had apparently known of the imminence of his posting and chosen his moment perfectly. Steps were taken to find him in the United States, and at the same time the GRU asked for permission to murder him from the Central Committee. However, the Central Committee turned down the request on the basis that the major was incredibly cunning and could well outwit the GRU a second time as he had outwitted them earlier. They were ordered to forget about the major and stop searching for him. Now, whenever a 'walk-in' appears at a Soviet embassy and suggests the purchase for an exorbitant price of technical documents of exceptional importance, GRU residents always remember the American major.
That it is extremely difficult to find real volunteers is a simple fact. It is much, much harder to discover a volunteer than an agent whom the GRU has spent a year and more in processing. But real volunteers, however warmly they may be welcomed, do not take into consideration another simple thing. The Soviet operational officer, having seen a great deal of the ugly face of communism, very frequently feels the utmost repulsion to those who sell themselves to it willingly. Even amongst those few who still believe in communism, the intelligence officer will make a great distinction between the agent he has recruited by using a whole arsenal of tricks and traps, and the volunteer. And when a GRU or KGB officer decides to break with his criminal organisation, something which fortunately happens quite often, the first thing he will do is try to expose the hated volunteer.

Agent Communications
GRU theoreticians officially admit that agent communications -that complex of channels for transmitting instructions and material - is the weakest link in the chain. It is the fault of communications, they say, that there are so many failures, and to some degree they are right. Whatever the theoreticians say, however, we in the field know that by far the greatest damage to Soviet intelligence is caused by the defection of GRU officers. Enormous damage was done when Igor Gusenko went over to the West. By this one gesture the whole powerful current of technological intelligence on the production of atomic weapons, which was flowing like a river into the hands of Stalin and his blood-thirsty clique, was stopped dead. And historians will remember with gratitude the name of the GRU Colonel Oleg Penkovsky. Thanks to his priceless information the Cuban crisis was not transformed into a last World War. Nevertheless, it is indisputable that after the phenomenon of willing and mass defection to the side of the enemy, which was clearly absent in the old Russian intelligence service of the pre-revolutionary period, agent communications is the most vulnerable sector of Soviet intelligence.
