During the Battle of the Bulge, the Germans disguised several Panther tanks as U.S. M10 tank destroyers (“Ersatz M10”). Part of the Operation Greif created and commanded by Otto Skorzeny, Panzer Brigade 150 deployed these Panther Ausf. G tanks which had been extensively modified and painted to resemble U.S. M10 tank destroyers.
