Concrete structures, also known as “Lego blocks”, will be placed along Latvia’s border with Russia and Belarus.
Construction is underway on the first phase of the Baltic Defence Line in Latvia’s easternmost region of Latgale.
Pyramidal obstacles made of reinforced concrete have been transported on trucks to the area, where they will be used to protect the external borders of Latvia and Europe.
For now, the army is placing the obstacles together in depots owned by municipalities or state institutions near the border with Russia and Belarus.
They will then be placed at intervals along the border in places the National Armed Forces considers necessary.
The countermeasure is to bury them with large bulldozers, but this still forces an insurgent army to cross within a focused area, as opposed to anywhere along the border. They buy time, advanced warning, and restrict enemy maneuverability.
