According to the source, the breakthrough was carried out by units of Russia’s 1st Tank Army, which managed to dismantle Ukrainian defensive positions in this sector. During the assault, a concentrated and coordinated strike was launched on Ukrainian positions, including fortified strongpoints held by formations of Ukraine’s 3rd Army Corps.
