| Notes | The StuGIG33B was another attempt to mobilise the 150mm sIG33, this time on the chassis of a StuG III. Some sources say that the chassis of various StuG IIIs were modified and used. The gun was mounted in an armoured citadel built directly above the superstructure, which gave it an advantage over the previous models buy having all round protection and armoured roof. Traversing the gun was limited to only 3° left and right and 30 rounds were carried. The StuGIG33B served on the Russian front with one company taking part with in the battle of Stalingrad, whilst another company took part in the failed relief attempt. |
