Sdkfz 263 Fu (8-rad) - Click for larger version of the photo
A nice "action shot" probably from the early stages of the invasion of Soviet Russia.
Note the tactical markings painted on the front - The German Wehrmacht used a very elaborate system where symbols could be combined to mark the vehicle at its exact position within an organisation.
That would place this 263 with an armoured car unit (simplified drawing of armoured car in profile) it's a signals unit (rectangle around the car) it's serving with the 2'nd battalion (white pointed flag with the letter 2 on the far right), and attached to the Divisional staff (large pointed flag on the far left)
Above the tactical sign is a "Y", the divisional sign of the 7'th Panzer Division
