That is a Bergepanther Ausf D that was fitted with a turret in the field. The Bergepanther D was used as a tow vehicle for disabled Tigers, Panthers and other tanks, The Berge D came out first and was followed by the D version. Unlike the Bergepanther Ausf A, which had a winch and a spade to remove bogged tanks it could only tow a tank like an armored FAMO.
I have seen another photo of the same Bergepanther from a different angle. I have been told by others that the turret was welded in place and could not rotate. You can shot back atleast and you look like any other tank to an observer, park it near the line and they would think you have another tank and a new type also.
Thanks for posting the picture.
