Russian forces gained 4,168 square kilometers, largely comprised of fields and small settlements in Ukraine and Kursk Oblast, at a reported cost of over 420,000 casualties in 2024. Ukrainian Commander-in-Chief Colonel General Oleksandr Syrskyi stated on December 30 that Russian forces suffered 427,000 casualties in 2024.[1] ISW has observed geolocated evidence to assess that Russian forces advanced 4,168 square kilometers in 2024, indicating that Russian forces have suffered approximately 102 casualties per square kilometer of Ukrainian territory seized. ISW previously observed that Russian forces gained 2,356 square kilometers in exchange for an estimated 125,800 casualties during a period of intensified Russian offensive operations in September, October, and November 2024.[2] Russian forces made 56.5 percent of their 2024 territorial gains during the September through November 2024 period. Russian Security Council Deputy Chairperson Dmitry Medvedev claimed on December 24 that 440,000 recruits signed military service contracts with the Russian Ministry of Defense (MoD) in 2024, suggesting that Russia is likely recruiting just enough military personnel to replace its recently high casualty rates one for one.[3]
Russian advances have slowed in December 2024, however. ISW has observed geolocated evidence to assess that Russian forces gained 593 square kilometers or 18.1 square kilometers per day in December 2024, while the number of daily Russian casualties in December 2024 remained similar to the estimated daily casualty rate in November 2024. The Ukrainian General Staff reported a daily Russian personnel casualty average of 1,585 in December 2024, marking a fourth all-time high of Russia’s daily casualty rate following reports that Russia’s average daily Russian personnel casualty reached a new all-time high of 1,523 casualties per day in November 2024.[4] Russian forces were advancing at the notably higher rate of 27.96 square kilometers per day in November 2024.[5] Syrskyi stated on December 30 that Russian forces have suffered 1,700 casualties per day over the past week (since December 23), indicating the Russian forces may have suffered an even higher casualty rate in the last few weeks of 2024 even as Russian advances slowed.[6] The Russian military command likely tolerated record levels of personnel casualties from September through November 2024 to facilitate larger territorial gains, but it remains unclear if the Russian military command will be willing to sustain such casualties if Russian forces’ rate of advance continues to decline as Russian forces continue to advance on more heavily defended settlements such as Pokrovsk
