The operation near Lyman relied heavily on unmanned systems and deep strikes before committing infantry, including 36,000 strikes on Russian supply lines and more than 15,700 ground robot missions, with heavy bomber drones dropping kamikaze ground robots more than 10 kilometers behind enemy lines. Units also conducted two mechanized raids behind Russian lines, including a 4.5 kilometer advance that inserted infantry to destroy Russian drone teams, though Biletskyi said armored assaults now require "extremely detailed planning" like a special operation rather than serving as a conventional reserve.
Across four disclosed phases, the 3rd Army Corps reported recapturing 277 square kilometers and 16 settlements, inflicting 8,000 Russian casualties and taking about 250 prisoners, though open-source analyst AMK Mapping visually counted 78 to 90 captives in released video. The counteroffensive blocked Russian plans to flank the Sloviansk-Kramatorsk urban belt and cut the Kharkiv-Sloviansk highway, while President Volodymyr Zelenskyy said overall Russian losses across the front rose to 42,000 a month during the campaign from 30,000 to 32,000 earlier in the year.
