Lutsk, Ukraine Reuters When Stanislav Hulenkov signed up for Ukraine’s border guard in 2021, he sought a stable job on the quiet north-western frontier so he could continue his career as a rising judo star. Two years later, the 22-year-old disappeared on an artillery-scarred battlefield on the other side of the country. Hulenkov’s remains were identified 10 months after that, making him one of hundreds of Ukrainian athletes killed in Russia’s full-scale invasion.
