Russian infantry use gas pipeline to infiltrate Kupiansk

Russian military forces are reportedly using a disused gas pipeline to infiltrate infantry groups into the Ukrainian city of Kupiansk in Kharkiv Oblast. The tactic is aimed at bypassing Ukrainian defenses by using old infrastructure that still runs into the city, specifically targeting the Holubivka route. This method allows for undetected movement of personnel into urban areas, representing an unconventional approach to ground assaults in the contested region. The development highlights the ongoing and fluid nature of frontline combat tactics in eastern Ukraine.
