Absolutely fantastic collection, Patrick!
You really couldn't ask for more than that as a reference!
Peter - I came across this photo of a company tailor early on in North Africa on the Bundesarchiv site last week. Based on the photo - I'd kit figures in shirtsleeve order wearing no extra gear or carrying no weapons as they aren't fighting. Gear and weapons could be stacked nearby or on / in vehicles as part of a larger scene in a diorama.

Pretty sure the photo is exactly the reference you need since your collection focuses on North African subjects.
Hope this helps,
Fred
