Latvia is building anti-tank trenches and concrete dragon's teeth along its eastern border with Russia, with four of 89 planned kilometers of trenches completed so far. Ukrinform, citing LSM, reported on 10 November that the work forms part of the Baltic Defense Line. Trenches more than five meters wide have already been dug in the Balvi Municipality border area, where National Guard troops are completing deployment, and five kilometers of dragon's teeth have been installed so far. Each concrete obstacle weighs 1.5 tonnes and stands slightly over one meter tall. They are being placed in three rows, with trenches to be dug alongside them later. Latvian Television said the first 27 kilometers are expected to be finished by next spring. Fortifications will not cover the full border with Russia and Belarus, which exceeds 450 kilometers, because swamps, lakes and dense forests provide natural protection, so artificial obstacles are going where heavy equipment could most easily advance. National Guard staff sergeant Edgar Briedis said the obstacles are spaced so vehicles cannot cross them and linked so they cannot be pulled out individually, and that combining types forces an enemy to use different equipment. Work will continue through winter. A reported 303 million euros has been allocated through 2029, and the funding also covers other defensive systems. In October, parliament adopted a law establishing counter-mobility infrastructure for the line.
