Finland is considering the possibility of building anti-tank trenches and other defensive structures along the border with Russia, Bloomberg reports, citing the country's ground forces commander, Passi Valimki. The Finnish military is testing anti-tank barriers similar to those in Ukraine. The army is evaluating how the fortifications will behave in the harsh northern climate. The commander said that Finland's goal is to strengthen the defense of NATO's eastern flank within the "restoration of Russia's military potential."
