A Ukrainian unit, reportedly the Biletsky Corps, has inflicted significant losses on an elite Russian drone unit, "Rubikon," leading to its withdrawal from the Lyman-Brovary direction. The "Vivaldi" operation by the Third Army Corps systematically targeted "Rubikon's" logistics, ammunition depots, drone launch points, and personnel.

The Ukrainian unit, identified as the Biletsky Corps, reportedly targeted "Rubikon's" logistics, ammunition depots, drone launch points, and experienced operators. This action is said to have significantly disrupted the unit's command and control system, leading to Russian soldiers abandoning positions and equipment. Consequently, Russian command decided to redeploy "Rubikon" to another front to preserve the unit.
