These attempts at breakthroughs occur around the clock. The occupiers seek to use the speed and surprise factor to disorient Defenders of Ukraine and strike at the fortifications. However, the hope of surprise does not work - the border guards demonstrate cool composure, accuracy and technological superiority. The report is accompanied by a corresponding video, which demonstrates the skillful work of FPV drone combat crews in destroying russian troops:
Defense Express reported earlier, that Ukrainian forces were successfully pushing back Russian assaults in the Kupiansk sector thanks to precise and powerful fire from the Croatian RAK-SA-12 multiple launch rocket system. Operated by a fire support unit within the 3rd Border Guard Detachment, this system proved highly effective in halting enemy advances and disrupting their formations.
