Russian forces on the Ukraine-Russia front have shown their BTM-3 trench digger. Although this machine is very old, its efficiency in digging trenches is truly remarkable.
The BTM-3 is a classic military high-speed trench digger, developed during the Cold War era in the Soviet Union, and it is well known for its efficient operation in complex terrains such as permafrost. It was produced from 1957 until 1978. The BTM-3 can dig one kilometer of trench in an hour, with a maximum digging depth of 1.5 meters and a width of 1.1 meters. The work output of one hour by the BTM-3 is equivalent to the effort of hundreds of soldiers digging manually for several days or even half a month. This speed allows units to quickly build defensive positions or fortifications needed for offensives, greatly enhancing combat effectiveness. Russia later developed the BTM-4M "Tundra" trench digger, based on a more advanced chassis, further improving the operational efficiency, reportedly capable of digging up to 1200 meters of trench per hour.
The Ukraine-Russia conflict has brought the ancient trench warfare back to the center of the battlefield. In the era of drones and satellite reconnaissance, trenches have not become obsolete, but instead have shown new vitality through integration with modern technology.
