Ukrainian forces launched Operation Vivaldi near Lyman, resulting in the recapture of between 125 and 176 square kilometers of territory. The operation forced Russian units onto the defensive and dismantled the northern arm of a Russian pincer movement intended to encircle Donetsk.
To achieve these gains, the Third Army Corps integrated drones with massive artillery formations to create a 'kill zone' that blocked Russian equipment and reserves. This maneuver preserved critical Ukrainian supply routes and prevented Russia from threatening the 'fortress belt' from the north-east.
