Report by U.S. Think Tank: The Ukraine-Russia War Caused Nearly 2 Million Military Casualties or Disappearances

AFP, Washington, 27th. According to a research report released today by the American think tank "Center for Strategic and International Studies" (CSIS), Russia's ongoing aggression against Ukraine has led to nearly 2 million military personnel casualties, including deaths, injuries, or missing persons.

CSIS noted that since Russia's full-scale invasion of Ukraine nearly four years ago, Russia's losses have been even more severe, with an estimated 1.2 million casualties, including as many as 325,000 killed.

CSIS said: "Since World War II, no major power has experienced such a large number of casualties or deaths in a war. ... The Russian army's pace of advancement on the battlefield has been extremely slow."

CSIS also pointed out that Ukraine has also paid a heavy price. From February 2022 to December 2025, Ukrainian military casualties ranged from 500,000 to 600,000, with approximately 100,000 to 140,000 killed.

According to CSIS: "The total number of casualties from both sides of the war may reach up to 1.8 million, and by spring 2026, the total may reach 2 million."

In February 2025, Ukrainian President Zelenskyy told an American television media outlet that since 2022, Ukraine had lost nearly 46,000 soldiers, with tens of thousands missing or captured. Analysts believe this estimate is low.

British Broadcasting Corporation (BBC) Russian service and Russian independent media Mediazona confirmed that more than 163,000 Russian soldiers have died in the war over the past four years based on public information such as death notices, but they also stated that the real number may be higher.

This war has also caused significant civilian casualties. The United Nations (UN) monitoring unit found that the number of civilian deaths in Ukraine in 2025 was second only to 2022.

The Office of the United Nations High Commissioner for Human Rights (OHCHR) stated that more than 2,500 civilians were killed and more than 12,000 were injured in 2025, while noting that the United Nations has confirmed that the number of civilian deaths since 2022 is close to 15,000, but the actual total number is "likely much higher."
