The first dozen were delivered by the end of October 1942 and assigned to Sturmgeschütz-Abteilungen (Assault Gun Battalions) 177 and 244, then fighting in Stalingrad. The remaining dozen vehicles could not be delivered to Sturmgeschütz-Abteilungen 243 and 245, also fighting in Stalingrad, after the Soviets surrounded the German 6th Army on 21 November. Instead, the vehicles were formed into Sturm-Infanterie-Geschütz-Batterie/Lehr-Bataillon (Assault Infantry Gun Batterie/Demonstration Battalion) XVII. The battalion was assigned to the 22nd Panzer Division as the Germans attempted to relieve the trapped 6th Army. The division was virtually wiped out in the fighting and the battery was assigned to the 23rd Panzer Division where it became the Sturm-Infanterie-Geschütz-Batterie/Panzer-Regiment 201 (also known as 9. Kompanie/Panzer-Regiment 201) for the rest of the war. The last strength report to mention them lists five remaining in September 1944.
A 150 mm heavy infantry gun (with an actual caliber of 149.1 mm) from the World War II era. The abbreviation stands for schweres Infanteriegeschütz 33 (heavy infantry gun, Model 1933). It was used to destroy fortifications and eliminate enemy personnel.
If you want to use the 3BR in your research, keep in mind that the reload time will be comparable to that of the KV-2.
If they apply what they did to the open top version of this then they will ignore the slow speed issue and use the enclosed hull and the mg just like the jagdpz4 short barrel
The more armor on ISU-152 isn’t that much better to begin with since it’s only slightly angled 90mm and this vehicle would be much faster than ISU-152 since it used Stug 3 chassis which is basically a Panzer 3 chassis.
So turns out that StuIG 33 B was so overloaded by 15cm gun with thicker armor that it’s max speed was severely hampered, the max speed was indeed only 20km/h i didn’t know that this tank was that slow because the Sturmpanzer 4 was actually still quite fast despite all the armor and 15cm gun i guess i underestimated the chassis difference between Panzer 3 and Panzer 4.
One small correction tho, ISU-152 has 35 km/h max speed in Enlisted not 40 km/h.
I’ll say this, if StuIG 33 B gets the same reload speed as Sturmpanzer 2 it should be still BR 4. If it gets slower reload speed than the Sturmpanzer 2 then i’m fine with it on BR 3.
