yang kyoungjong () is the name of a supposed korean soldier who, according to historians, fought in the imperial japanese army, the soviet red army, and later the german wehrmacht during world war ii. he is, to date, the only soldier in recent history thought to have fought on three sides of a war, and this status has earned him recognition. although both popular news outlets and several historians have regarded this as a fact, a korean documentary said there was no clear evidence of his existence.
