Ukraine's Operation Vivaldi and Drone Tactics Drive Multi-Sector Gains Against Stalled Russian Offensive
Ukrainian forces have advanced in four frontline sectors, including near Kupyansk and Chasiv Yar, while Russian gains remain limited. The Institute for the Study of War (ISW) notes that Ukraine's Operation Vivaldi in the Lyman direction has successfully disrupted Russian plans to encircle the Donetsk Fortress Belt. This progress is attributed to rigorous operational security and a sustained strike campaign that degrades Russian electronic warfare capabilities, allowing Ukrainian drones to achieve tactical overmatch. Meanwhile, Russian forces are preparing mechanized assaults for the fall in the Dobropillya direction, though they have failed to advance in northern Kharkiv.
