Ukraine's military dismissed the commanders of the 14th Separate Mechanized Brigade and the 10th Army Corps on April 25, 2026, after photographs showed emaciated soldiers, according to research from four sources. The scandal erupted when the wife of one soldier posted pictures on social media, prompting an investigation. The Ukrainian General Staff acknowledged command errors and deliberate concealment of conditions by officers. Soldiers at a bridgehead on the left bank of the Oskil River near Kupiansk went without food for up to 17 days and lost weight from 80-90 kg to approximately 50 kg, according to Anastasiia Silchuk, wife of a soldier. Russian drone attacks severed supply lines across the Oskil River, forcing supplies to be delivered by boat or drone, the Ukrainian General Staff said.
Russian forces made significant territorial gains in 2025, seizing 4,831 square kilometers of Ukrainian territory, according to research from four sources. This amounted to 0.8 percent of Ukraine's territory. Data from the Ukrainian General Staff indicates Russian forces suffered 416,570 casualties throughout 2025, an average of 78 casualties per square kilometer seized in Ukraine and Kursk Oblast. The average daily Russian rate of advance in 2025 was 13.24 square kilometers per day, higher than 9.87 square kilometers per day in 2024, according to research from four sources. However, Russia's slow grind in 2025 gained it less than an additional 1 percent of Ukrainian territory at a massive cost estimated at over 200,000 troops killed and wounded, according to research from four sources. The discrepancy between 416,570 casualties and over 200,000 killed and wounded likely reflects different counting methods: casualties include killed, wounded, missing, and captured, while 'killed and wounded' may be a subset.
Russia’s concentration of fiber optic drones with ranges of more than 20 kilometers in the Siversk direction enabled Russia’s seizure of Siversk.
Russian forces adapted their tactics in 2025, employing a new operational template relying on battlefield air interdiction, tactical interdiction, infiltration missions, and mass small group assaults, according to research from four sources. They began achieving BAI effects by using UAVs to interdict Ukrainian ground lines of communication in early Spring 2025. The Russian military proliferated elite drone operators of the Rubikon Center across the frontline in April and May 2025. Russian forces scaled production of fiber optic UAVs resistant to electronic warfare, increasing range from roughly 7 km in early Spring 2025 to around 20 km in Summer 2025, according to research from four sources. They also introduced 'mothership' drones that can carry and extend the range of FPV drones. Recent Russian technological adaptations extended the range of fiber-optic drones to between 50 and 60 kilometers. Colonel General Oleksandr Syrskyi, Ukrainian Commander-in-Chief, stated: "Russia's concentration of fiber optic drones with ranges of more than 20 kilometers in the Siversk direction enabled Russia's seizure of Siversk."
Ukrainian soldiers liberated from Russian captivity lost 40-50 kg of weight during their stay in Russian torture chambers, according to photographers Kostiantyn and Vlada Liberovs. The photographers released the photos with the permission of the defenders and sent some to the Peace Summit in Switzerland. The conditions faced by Ukrainian prisoners of war have drawn international concern, though the exact number of affected soldiers remains unclear.
Several unknowns remain unanswered. It is not known what specific actions were taken against the dismissed commanders beyond their removal. The exact number of Ukrainian soldiers affected by the starvation conditions at the Oskil River bridgehead has not been confirmed. The timeline between the posting of the emaciated soldiers' photos and the dismissal of commanders is unclear. It is also uncertain whether the emaciated soldiers reported by Svenska Dagbladet are the same as those at the Oskil River bridgehead. The current status of the soldiers who lost weight in Russian captivity has not been disclosed.
