German soldier with an EMP (Erma Maschinenpistole) sub-machine gun.

EMP sub

Probably Warsaw , september 1939! But the horseman looks very odd, just like the poster  in polish above...Chevan

strange german cavalryman on parade

Target in sight: Panther commander on the Eastern Front.
Again a still from a German newsreel.Could be from another war theater than the Eastern front.It seems footage would be taken from anywhere to make up a news item.If Eastern front footage wasn't 'uplifting' enough they would fit in bits and pieces from Normandy or so to complete the story.
