The photographs could have been ironic for a long time, if not for the seriousness of the situation. Essentially, if Lithuania is a dagger against the Kaliningrad region, then Estonia is against St. Petersburg. Apparently, one of the main goals is to neutralize the Baltic fleet in future conflict. Now the DCFB is perhaps the most modern of all the operational and strategic associations of the Russian Navy: in ten years it received 5 units of patrol ships only (4 projects 20380 and 1 project 11540). Not to mention the fact that both Kaliningrad and the Leningrad Region are vital regions of the country.
There is something to think about. In the meantime, you can see exactly how the Estonian military are going to repel the hypothetical offensive of the Russian army.
