| Notes | The Brummbär was a heavy self-propelled support howitzer mounted in an armoured citadel on the chassis of a Panzer IV tank. It was armed with a Skoda 150mm StuH 43 howitzer. Early versions were prone to breakdown, this was mainly due to the excess weight. It took four series to iron out most of the problems and the main modifications were; extra armoured protection for the driver, more ventilation added, two steel rimmed road wheels, a lightened version of the main gun, cupola and ball mounted MG added to the hull from. Chassis from five versions of the Panzer Mk. IV were used and these were Ausf G, E, F, H & J. The Brummbär was issued to Sturm battalions and fought on the eastern, western and southern fronts. |
