The panzerkampfwagen I sIG.33 Ausf. B with 150mm self-propelled gun was developed to provide armored infantry with immediate fire support from a self-propelled armored platform which could follow them closely in action. Used to equip sIG(Sf) Kompanien (Heavy Infantry Gun (SP) Companies) 701-706, which were allocated to six Panzer divisions before the campaign in Belgium, Holland and France in May-June 1940. Deemed obsolete later in the war, several were still in service in mid 1943 with the schwere infanteriegeschutz Abteilung 704 of 5. Panzer Division then serving in Russia. Sold Out!
