Finland is considering the possibility of creating anti-tank barriers to protect NATO's eastern flank amid the "restoration of Russia's military potential." The commander of the Finnish army Passi Vlimki said this in an interview with Bloomberg. Finland has a long border with Russia (1,340 km), and military leaders need to understand how fortifications - for example anti-tank trenches - will behave in harsh northern conditions and whether they will turn into "artificial ponds" due to the climate, explained Lt. Gen. RBC channel in "Max".
