Russian Cumulative Losses Reach ~1,369,340 — Daily Attrition ~1,300 KIA+WIA — Day 1,561

Ukraine's General Staff reported on June 4, 2026 (Day 1,561) that Russia's estimated cumulative military personnel losses since February 24, 2022 reached approximately 1,369,340 killed and wounded — increasing by approximately 1,300–1,400 per day. The daily attrition rate reflects Russia's continued high-tempo offensive operations across the Donetsk, Zaporizhzhia, and Kharkiv fronts despite minimal territorial gains. ISW assessed that Russia's spring-summer 2026 offensive had largely stalled, with Russia's May 2026 gains a fraction of May 2025 gains. Russia captured Pokrovsk and Myrnohrad in early 2026 but subsequent westward advances have been marginal. Netherlands MIVD (April 2026 assessment) estimated ~1.2 million permanent Russian losses — figures broadly consistent with Ukrainian General Staff tallies. Ukraine's CINC Gen. Syrskyi noted Russia is struggling to find replacement soldiers, while Ukraine has seized the tactical initiative in several sectors with Ukrainian assault operations now outnumbering Russian assaults — a first for the full-scale war.
