To my mind this does not show him in Nort Afrika, but possible at the East front or in Ardenne some 1944-45.

The Bundesarchiv caption dates this image to 1941.  It is not possible to identify the German force carrying out this execution.  Since it involves a firing squad consisting, roughly, of two soldiers to each of the condemned, it seems very unlikely that this was a part of any "special action".  More likely a "collective punishment" for some action against the German forces carried out by the local population, or by early partisans in the area.  Best regards, JR.
