Kostiantyn Vlasenko was huddled in a hole under the boiler of a bombed-out school when he came to a terrifying conclusion: To survive, he needed to amputate his only remaining foot. The Ukrainian infantryman had already lost his left foot in a Russian drone strike in February. His right leg was broken and bent in the same attack, hindering his ability even to crawl. About three months later, after working up the courage, he grabbed his knife, sliced off his foot and applied a tourniquet to staunch the bleeding.
