Ukrainian forces have conducted Operation Vivaldi since mid-2026 along the Lyman axis in northern Donetsk Oblast, recapturing roughly 176 square kilometers and multiple settlements through targeted strikes on Russian logistics, drone jamming, and ground robot deployments. Terny, a village near Lyman previously recaptured by Ukraine in 2022 and seized by Russian units in January 2025, sits amid this active sector where both sides contest approaches to the Kramatorsk-Sloviansk defensive line. Russian forces continue probing and infiltration attempts across the broader Donbas front, while Ukrainian commanders prioritize disrupting reinforcement routes and consolidating gains west of the Siverskyi Donets River. No verified Ukrainian advance into Terny has been reported in recent assessments, and resolution hinges on ISW mapping confirming territorial control by the market deadline amid ongoing positional warfare.
