11. More than 400,000 Russian soldiers are estimated to have been killed or wounded in 2025, according to a British defence intelligence update on Ukraine. In October 2025, defense intelligence put the overall number of Russian casualties throughout the full-scale war at 1,118,000, higher than the entire size of its army before the full-scale invasion. Russia has thrown men into “meat-grinder” assaults to seize land in eastern Ukraine inch by inch. The casualty rate has been particularly high in this year’s effort to take the key hub of Pokrovsk, which has still not entirely fallen. (Source: telegraph.co.uk)
