The Russian government’s using the atmosphere of threat allegedly posed by NATO member states to the oblast is used as an excuse for the organisational changes in the Baltic Fleet launched in spring 2016. On 1st April the decision was taken to reform the 11th Army Corps on the base of existing ground units, and supplies of new weapons were promised. The Russian side has so far limited itself to creating the command structures and the staff for the new corps, but no new combat units have been developed. The deployment of new weapons systems has significantly expanded the spectrum of the Russian troops’ attack capabilities and has enabled the creation of a so-called Anti-Access/Area Denial (A2/AD) zone based on Kaliningrad Oblast. If the zone is created, the territories and airspaces of the neighbouring NATO member states and, considering the range of Kalibr missiles, also the entire Central Europe and Scandinavia will be within the range of Russian weapons. One consequence of the increasing militarisation of the oblast is the intensified activity of the secret services and other institutions of force. A special role is played by the structures of the Federal Security Service (FSB) and the Federal Protective Service (FSO) which are in charge of the oblast’s counter-intelligence protection and governmental special communication. Over the past few years the oblast has been playing an increasingly important role as a staging base for carrying out intelligence tasks in Lithuania and Poland. One proof that intelligence activity has intensified is found in the fact that tasks which have the nature of classical political intelligence are carried out by the FSB which, according to the competences act, is only tasked with shallow trans-border intelligence. The fact that proves that such actions are taking place is the indictment brought against the FSB officer Nikolai Filipchenko who was detained in Lithuania on charges of attempting to recruit officers of the Lithuanian services tasked with protecting the premises used by the president of Lithuania.
