The Panzer-Lehr-Division was an elite German armoured division during World War II. It was formed in 1943 onwards from training and demonstration troops stationed in Germany, to provide additional armored strength for the anticipated Allied invasion of western Europe. On 4 April 1944, the division was officially designated as the 130th Panzer Division; however, it is usually referred to as the Lehr Division. It was the only Wehrmacht Panzer division to be fully equipped with tanks and with halftracks to transport its mechanized infantry. On several occasions it fought almost to destruction, in particular during Operation Cobra, and by the end of the war in Europe bore little resemblance to the unit that had originally been activated.
