What I am looking for is a source of information on What if any of units of SS Panzerkorps were equipped with Stug III's and what camo patterns they(SS)were using at this time. Thanks in advance guys.

I'm sure someone out there can add more detail to this answer but its a start.

Using SS Armor squadron book as a reference.

photo's in the book show vehicles with a base of Sand yellow with red/brown overspray.. and sand yellow with simple to complex patterns of olive green,

there are also a couple of photos of panthers in the new regulation 3 color scheme authorized in the february before.. but this was just beginning to come into effect.. (noted about 1 photo)

and it does appear that the SS used some stug III but not any photos of them in the kursk section.

Info on stugs in this book from photo captions.

Leibstandarte ss unit had StuG III ausf B's photo time perions 39-42

StuG-Abt LAH armor photo taken outside mariupon in southern russia.

StuG III Ausf G somewhere outside kiev around winter 43-44..exact ss unit unknown.

hope this is a start..
