The Germans were big on re-use of captured material. This leads to very interesting scenes for modelers or diorama builders.
One interseting photo showed up in a book on Patton's attack on Metz, France in the fall of 1944. A Russian 76.2mm field gun had been captured by the Germans and used by one of their units, then the gun was captured by the US Army and the photo shows it being fired by GIs against its former captors.
