I dunno, could it be the Red Stripe was for position as well as rank?
I think he was higher up than his status as a colonel would indicate. Wasn’t he the adjutant of the Reserve Army?
As far as vehicles and equipment, the short North Africa sequence looked pretty authentic with a large spread of half tracks, what looked to be a Panzer Mark IV (possibly a mocked up one though), some armored cars and Kübelwagens --other than the fact that the vehicles were grouped too closely together made obvious by what takes place in that scene-- it did look at least superficially authentic. But I guess they wanted to get as much proverbially “in the shot” as they could.
One thing I did notice was that most, if not all, of the officers had Walther PPK sidearms. I would guess that the P-38 would have been more prevalent, but I’m far from up on that sort of thing…
Also, the sequences of the Reserve Army battalion looked good and even authentic in a general sort of way. But I wonder if the uniforms seemed a bit dated with the tighter fitting early WWII designs, but since they were primarily garrison troops, this may well be correct. They also had the typical Mauser rifles and MP-40 submachine guns, but I would also think that at least a few of the other numerous weapon designs might have filtered down by the middle of 1944 and it may have looked a bit more hodgepodge with the situation beginning to deteriorate? Then again, I recently saw “Downfall” for the first time and a lot of the Heer/SS soldiers (almost a majority) carried the MP-44 in it, in fact maybe it was just a little more prevalent than I would think it actually was…
