According to Ukrinform, this was stated by the commander of the Land Forces of Finland, Lieutenant-General Passi Välimäki, Bloomberg reports.
Russia has already begun to restore its military potential, even though its full-scale invasion of Ukraine is now in its fifth year.
In this conflict, Ukrainian troops used extensive defensive lines and anti-tank obstacles to slow the enemy's advance, Valimäki said.
With a 1,340-kilometer border with the Russian Federation, which is about half of NATO's land border with that country, Finland must determine how structures similar to those used in Ukraine will be handled in a strict northern weather.
“Conditions in Finland are more difficult,” said Valimäki. - If we build fortifications and dig anti-tank ditches or obstacles of the same depth as in Ukraine, how long will it take before our environment turns them into artificial ponds?”
