Total killed and injured in Ukraine war could soon hit 2 million — report

A new report warns that the number of soldiers killed, injured or missing on both sides of Russia’s war on Ukraine could hit 2 million by the spring, with Russia suffering the largest number of troop deaths recorded for any major power in any conflict since World War II.

The report from the Center for Strategic and International Studies comes less than a month before the fourth anniversary of Moscow’s full-scale invasion of Ukraine on February 24.

The CSIS report, released today, says Russia suffered 1.2 million casualties, including up to 325,000 troop deaths, between February 2022 and December 2025.

“Despite claims of battlefield momentum in Ukraine, the data shows that Russia is paying an extraordinary price for minimal gains and is in decline as a major power,” the report says. “No major power has suffered anywhere near these numbers of casualties or fatalities in any war since World War II.”

It estimates that Ukraine, with its smaller army and population, has suffered between 500,000 to 600,000 military casualties, including up to 140,000 deaths.

Neither Moscow nor Kyiv gives timely data on military losses, and each side seeks to amplify the other side’s casualties.
