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.
Al lot of the same properties as a mine field. An unobserved mine field is quite quickly passed through. The issue primarily arises when you need to clear a mine field while under fire.
Combine them with ditches, barbed wire, possibly mines, and have forward observers directing fire on anyone trying to break through, and they’re a real PITA for attacking forces.
Essentially, they give just a couple forward observers the power to hold up an attacking force for quite some time while reinforcements arrive, at which point you’ve lost whatever advantage of manpower or surprise you had when attacking.
