I.Abteilung/Fallschirm-Panzer-Regiment “Hermann Göring”. If you look carefully you can see the Luftwaffe eagle on the crew’s caps. The tank’s commander in the turret (wearing a Knight’s Cross) would be the later Lieutenant Colonel, Oakleaf holder and commander of Fallschirm-Panzer-Regiment “Hermann Göring”, Karl Rossmann (1916-2002). Note that the tank (Panther Ausf. G, serial number 121081) is painted in the rare “disc pattern” which means your picture was taken not earlier than autumn 1944. Nice photo you got there!
