In the background

[sapper740]

I've attempted to ID the vehicle in the background to no avail. The rims almost look CMP, although I'm not sure.. Perhaps it's a captured vehicle that has had a command box built on the back? This vehicle could be German, Italian, or British or perhaps even something else. It's an interesting picture, Rommel is awarding a medal to his Italian compatriots...perhaps these Italian officers can be found in the World's Thinnest Book? Any ideas as to what type of truck this is?
