during the Korean and Vietnam wars combined.Almost one in 20 Ukrainian fighting-age men have been killed or injured because of the war, The Economist wrote.In September, the Wall Street Journal provided similar estimates, positing that Ukraine had lost 80,000 soldiers killed and 400,000 wounded. The outlet estimated Russia's losses at up to 200,000 killed and 400,000 injured.The exact figures for both sides are nearly impossible to establish as Kyiv and Moscow are secretive about their casualties. The last figure provided by Russian authorities was 5,937 killed soldiers as of September 2022.In turn, the General Staff of Ukraine's Armed Forces put Russian overall losses at over 735,000 as of Nov. 27. The losses Russia suffered in the full-scale war are believed to be greater than during all the wars since 1945 combined.According to The Economist, civilian casualties are even more difficult to establish but likely reach many tens of thousands.
