The war in Ukraine has shifted underground, with soldiers fighting in abandoned gas pipelines and tunnels. Ukrainian troops advanced over 15 kilometers in the Kupiansk area during Operation Veles, capturing over 30 Russian soldiers and inflicting significant casualties. The operation involved drone attacks above ground to prevent Russian forces from flanking Ukrainian positions. Ukrainian forces adapted to the underground warfare, facing fierce battles within narrow pipelines where Russians fortified positions. Additionally, the 425th Assault Regiment cleared a section of a gas pipeline, enduring harsh conditions during their operations.
