Russia builds frontline tunnels to evade drones

Russian troops are constructing an extensive network of underground tunnels near the frontline in Ukraine. The tunnels are designed to allow for the covert movement of personnel, equipment, and supplies between positions, shielding them from detection and attack by Ukrainian reconnaissance and attack drones. This tactic represents a significant adaptation to the pervasive threat of unmanned aerial systems on the modern battlefield. The construction effort highlights Russia's attempts to mitigate Ukraine's technological advantages in drone warfare.
