Russian forces maintain tactical pressure on Kupiansk front across Oskil River

Russian forces are conducting localized, sporadic advances on both banks of the Oskil River near Kupiansk, resulting in a fragmented front line characterized by small-unit infiltration. While Russian units have secured Radkivka, the surrounding areas and Holubivka remain contested gray zones with ambiguous control. This pattern indicates a shift toward attritional, small-group maneuvering rather than large-scale offensive breakthroughs.
