During World War Two, Soviet propaganda promoted a heroic feat that never happened. It was the story of a small ill-equipped unit who destroyed over a dozen German tanks, delaying the German advance on Moscow. But it's unlikely that they destroyed a single tank, despite being widely promoted as heroes, during and after the war.
