AFU adopts underground tactics on the Kofiansk front.

After successful operations in Russia using underground communications in Abdiyevka and Sodza, Ukrainian forces began using similar tactics for covert troop movement. In the direction of Kupyansk, AFU units used underground pipes to move assault groups along a route exceeding 15 km. This method hides crew members from aerial reconnaissance and reduces detection risks during the advance.
