In late November 2024, based on all previous estimates of Ukrainian military casualties, The Economist estimated Ukrainian losses at between 60,000 and 100,000 killed and 400,000 wounded.[96] On 8 December 2024, US president-elect Donald Trump claimed 400,000 Ukrainian soldiers had been killed and seriously wounded so far during the war. Subsequently, President Zelenskyy announced 43,000 Ukrainian soldiers were killed and 370,000 were wounded, but that “approximately 50%” of these soldiers recovered and had returned to active duty.[9
