General Staff: Russia has lost 1,355,940 troops in Ukraine since Feb. 24, 2022

Ukraine's General Staff reported on May 25 that Russia has suffered about 1,355,940 military casualties since launching its full scale invasion on February 24, 2022. The tally includes roughly 1,020 new casualties in the last 24 hours. The report lists losses across equipment and platforms, including 11,953 tanks, 24,608 armored combat vehicles, 99,000 vehicles and fuel tanks, 42,687 artillery systems, 1,802 multiple launch rocket systems, 1,390 air defense systems, 436 aircraft, 353 helicopters, 310,245 drones, 1,465 ground robotic systems, 33 warships or boats, and two submarines. Ukraine has not disclosed its own losses.

Independent Western think tanks say Ukrainian losses are substantially lower, with most estimates suggesting Russia's casualties are higher by roughly two to a bit more than two. The Center for Strategic and International Studies estimated in January 2026 that Ukrainian casualties range from 500,000 to 600,000 from February 2022 through December 2025, with 100,000 to 140,000 killed in action. The figures illustrate the scale of the conflict and the uncertainty around battlefield data.

Analysts note that casualty figures are fluid and depend on reporting practices, while official numbers from each side remain incomplete. The data reflect a war that has persisted for more than four years and show the heavy toll on personnel and materiel for Russia since the invasion began in 2022.
