High Quality Content by WIKIPEDIA articles! 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. Although initially the formation of units larger than a panzer regiment proposed by Heinz Guderian were rejected by the inspector of motorized troops Otto von Stuelpnagel[1], on his replacement by Oswald Lutz, Guderian's mentor, the attitude gained more support in the Army, and after 1933 was also supported by Adolf Hitler. On the 15 October 1935 the first three panzer divisions were formed. The 1st Division was formed in Weimar and commanded by Maximilian von Weichs, the 2nd Division was formed in Wurzburg and commanded by Heinz Guderian and the 3rd Division was formed in Berlin and commanded by Ernst Feßmann.
