Drones Reclaim Lost Ground and Guided Bombs Hit Bus: Battlefield Advances in Donbas Coexist with Civilian Costs

Russian forces attacked a bus in Kramatorsk, Ukraine, with a guided bomb, killing at least 30 and injuring dozens. The city is one of two fortress cities that Ukraine still controls in the Donetsk region.

According to NPR, the attack came as Ukrainian forces were announcing progress in their counteroffensive. Ukraine's 3rd Corps launched a counterattack codenamed "Operation Vivaldi" near Lyman, using electronic warfare, aerial drones, and unmanned ground vehicles to reclaim roughly 68 square miles of territory—an area about three times the size of Manhattan. Ukraine's claims about the size of territory reclaimed have not been independently verified, and the casualty figures from Kramatorsk come from local authorities and may be updated.

The operation's commander, 3rd Corps commander Andriy Biletsky, named the operation after Italian composer Vivaldi's violin concerto "The Four Seasons," and said the operation is still in its "first movement." According to video released by the 3rd Corps and cited by NPR, a soldier with the call sign "Jackson" said in Ukrainian: "As soon as they appear on our land, we quickly catch up with them and eliminate them."

According to NPR analysis, "Operation Vivaldi" took place in the Donbas region, which Russia has been trying to seize since 2014. Russia currently holds most of the region and is pressuring Ukraine to give up the remaining territory in a peace deal, a demand Ukraine has rejected. The report noted that "Operation Vivaldi" shows that Russia's full control over the Donbas is not inevitable and that Ukrainian forces can make breakthroughs on a drone-saturated battlefield.

But advances on the battlefield have not eased the sustained strikes on residents behind the front lines. According to Ukrainian officials cited by NPR, Russia has continued to strike Ukrainian energy and water facilities, causing power outages and supply shortages. Ukraine believes this is part of a broader Russian effort to make Ukrainian cities "uninhabitable"—an assessment drawn from Ukrainian statements and not verified by independent sources. Some residents are evacuating from cities under attack, including from the Ukrainian capital, Kyiv.

According to NPR's description, the Ukrainian operational flow is: first, electronic warfare and aerial drones disrupt Russian reconnaissance; then, they destroy Russian firepower and supply lines; next, small unmanned ground vehicles are sent in to weaken Russian positions; finally, assault groups clear the positions. On the battlefield, Ukrainian forces are using coordinated multi-domain unmanned systems to redraw the line of contact; behind the lines, Russian forces are pressuring cities with guided bomb strikes on buses and the destruction of water and power facilities.
