High Quality Content by WIKIPEDIA articles! The East Prussia Panzer Unit was an ad hoc combined arms unit created for operations out of East Prussia during the Invasion of Poland in 1939. It was generally called Panzer Division Kempf after General Werner Kempf assumed command, though it was only about half the strength of the other panzer divisions of the time. A panzer division is an armored division in the German Army. Panzer divisions are combined arms formations having both armor and infantry as organic components, along with the usual assets of artillery, anti-aircraft, signals, etc. that are common to most military divisions of the industrial era. However, the proportions of the components of a panzer division have changed over time.
