The Mobilisation Subdivision of the KGB of the LSSR (hereinafter – the Mobilisation Subdivision) was established in 1967 on the basis of the Mobilisation Groups of the Cadres Division of the KGB of the LSSR (active from 1954). It was directly subject to the Mobilisation Division of the KGB of the USSR; however, the personnel of the Division were in close cooperation with the management of the KGB of the LSSR as well as with the managers of all the divisions of the KGB of the LSSR. The main functions of the Mobilisation Subdivision were to coordinate the activities of the divisions of the KGB of the LSSR in order to be properly prepared for the special period (osobyj period), and to form the backup of the KGB of the LSSR. A great number of tasks was intended for the Mobilisation Subdivision, since in case of an emergency situation the backup of the KGB of the LSSR, besides the usual activities of the KGB, had to perform many specific functions. The Mobilisation Subdivision included the Lithuanian residents, who were the most dangerous to the Soviet regime, into the special records, and certain measures were planned to be taken against them in an emergency situation. In addition, foreign citizens located in Lithuania had to be arrested and interned in the emergency situation as well. In the summer of 1981 there were approximately 1000 foreigners in Vilnius and Klaipėda alone, and the Mobilisation Subdivision had their arrest plan prepared in advance. Another function of the Mobilisation Subdivision was to get ready for the evacuation of the structures of the Soviet government and the main apparatus of the KGB of the LSSR.
