Operation Greif (German: Unternehmen Greif; pronounced [ɡʀaɪ̯f], meaning "Griffin") was a special false flag operation commanded by Waffen-SS commando Otto Skorzeny during the Battle of the Bulge in World War II. The operation was the brainchild of Adolf Hitler, and its purpose was to capture one or more of the bridges over the Meuse river before they could be destroyed. German soldiers, wearing captured British and US Army uniforms and using captured Allied vehicles, were to cause confusion in the rear of the Allied lines. A lack of vehicles, uniforms, and equipment limited the operation and it never achieved its original aim of securing the Meuse bridges.
