War intensifies amid Russia’s summer offensive. Ukraine has spotted a massive redeployment of Russian self-propelled artillery and air defense systems to Sumy Oblast. 

Ukrainian forces have recorded a large-scale transfer of Russian military equipment from Crimea and Kherson towards Sumy Oblast. According to Petro Andriushchenko, head of the Occupation Studies Center, this is the largest movement of weaponry in the past six months.

“More than 10 self-propelled artillery systems, air defense systems, and convoys of over 40 trucks carrying ammunition and personnel,” Andriushchenko says.

The equipment is being loaded onto trains and sent to Russia’s Kursk Oblast, effectively heading to Sumy. The Russians are now stationed approximately 25-30 km from it. If they reach the city’s border, they will use artillery to strike it. 

Special attention is drawn to the military equipment markings, which, with their dominant tactical symbol of a triangle within a triangle, indicate reinforcement of this specific direction.

Amid this buildup, Sumy faces heavy drone attacks. Konotop mayor Artem Semenikhin stated that on 8 June, the region endured the most powerful drone assault since the war began: “The entire sky over the region turned red with targets.”
