Footage of the construction of defensive structures by the Russian army in the Krasnolimansky direction has been published. When creating dugouts, trenches, communication passages and weapons magazines, the engineering troops use the military mobile sawmill complex VMLK-1, more about it in the link to the video in the comments to the video. Since the war in Ukraine in some places turned into positional battles, quite serious defensive structures are being created. In the video you can see a system of trenches, the walls and floor of which are covered with boards, for protection from drones, and the upper part of the trenches is also closed. Along the entire length of the defensive structures, an electrical lighting system was created, drainage systems were installed, dugouts and firing points were created.
