A recent report from the Center for Strategic and International Studies (CSIS) confirms significant combat losses for Russia in its ongoing conflict with Ukraine. The report estimates Russian casualties at approximately 1.4 million, with about 450,000 fatalities, and notes that Russian advances have stalled. These developments highlight an extreme attrition rate and suggest a severely degraded offensive capability for Russia. The findings come as Ukraine has made substantial territorial gains, regaining more ground in recent months than Russia managed to capture in April 2026 alone.
