The General Staff of the Armed Forces of Ukraine reported on July 23 that Russia has lost approximately 1,434,690 troops since the full-scale invasion began on February 24, 2022. This figure includes 1,460 personnel losses recorded over the past day. The report also detailed significant equipment losses for Russia, including 12,191 tanks, 24,994 armored combat vehicles, and 423,588 drones. Ukraine's General Staff has not disclosed its own losses, citing operational secrecy. Independent Western think-tank reports, such as those from the Center for Strategic and International Studies (CSIS), suggest that Russian casualties significantly outnumber Ukrainian losses, with estimates placing the ratio between 2.5:1 and 2:1. A January 2026 CSIS report estimated Ukraine's total casualties between February 2022 and December 2025 to be between 500,000 and 600,000, with 100,000 to 140,000 killed in action. Ukrainian officials have rarely disclosed casualty figures, though President Volodymyr Zelensky stated in February that at least 55,000 Ukrainian soldiers had been killed in action.
