Modern myths and legends about communist past in Poland

Interestingly, as far as I remember, only the Pole survives.

Silesian Vladislau, to my best knowledge, played by that action film actor, Bronson. And their commander, too, played by Lee Marvin.
That film was so late on the screen in Poland because it was colour while all Polish war films from 1960s and early 1970s were black and white.

Who served in the Polish army before the war.

Mission Imposible. :):):)

There is probably a scene in the movie where his colleagues ask him if this (rope climbing) was taught like that in the Polish army, specifically in the navy.

Yes, indeed, there is such a scene. But his mates laugh so it means they crack a Pollack joke on him.
