Russian forces may be suffering losses along the entire front in Ukraine at a rate close to the rate at which Russia is currently generating new forces. Ukrainian Ground Forces Command Spokesperson Lieutenant Colonel Volodymyr Fityo stated on December 7 that Russian forces lost almost 11,000 personnel (presumably killed or rendered hors de combat by injury) in the Kupyansk, Lyman, and Bakhmut directions in November 2023. The operational tempo in the Kupyansk, Lyman, and Bakhmut directions is currently lower than in the Avdiivka direction. These reported losses suggest that the Russian casualty rate in the Avdiivka area may be even higher given the higher operational tempo there. Ukrainian officials previously reported that Russian forces lost 5,000 personnel killed and wounded near Avdiivka and Marinka (west of Donetsk City) between October 10 and 26, when Russian forces launched two waves of heavily mechanized assaults to capture Avdiivka. Russian forces are currently conducting mass infantry-led assaults to capture Avdiivka in an apparent effort to conserve armored vehicles despite the risk of even greater manpower losses. Ukrainian officials have notably indicated that Russian defensive efforts are resulting in significant casualties as well, with Ukrainian forces reportedly killing over 1,200 Russian personnel and wounding over 2,200 on the east (left) bank of Kherson Oblast between October 17 and November 17.Ukrainian forces continue counteroffensive operations in western Zaporizhia Oblast and are likely inflicting similar losses on defending Russian forces in this sector of the front. ISW cannot confirm Ukrainian-provided Russian casualty figures, and reliable figures for Russian casualties in Ukraine are not available. If the Ukrainian-provided figures are generally accurate they suggest that Russian operations in Ukraine are highly attritional overall and that high Russian losses are not just the result of the costliest Russian offensive operations near Avdiivka.
