According to a declassified US intelligence report cited by the Reuters news agency in December, the war in Ukraine had resulted in 315,000 dead and injured Russian troops.
The casualty toll accounts for nearly 90 percent of the personnel Russia had when the conflict began, Reuters reported, citing a source familiar with the intelligence.
The report also assessed that Moscow's losses in personnel and armored vehicles to Ukraine's military have set back Russia’s military modernization by 18 years, according to Reuters.
A top British military official said last summer that "Russia has lost nearly half the combat effectiveness of its army" since invading Ukraine in February 2022.

On Thursday, Ukraine's President Volodymyr Zelensky appointed Col. Gen. Oleksandr Syrskyi as the new commander-in-chief of the Ukrainian armed forces.
