What if, after a long night of Schnapps and Schuhplattler, a Sturmpanzer II and a Stug made sweet sweet love, and had a big baby boy that was fed a diet of the best Knockwurst and Strudel in Bavaria every day, and grew bigger, and stronger than his Mama and Papa. Then that baby boy would grow up to be the Sturm-Infanteriegeschütz 33B!
The Sturm-Infanteriegeschutz 33 was a heavy infantry gun carrier designed and produced by Alkett. From December of 1941 to October of 1942, total number of 24 s.I.G.33 auf Fgst. Pz.Kpfw.III (Sfl.) was made (chassis number 90101 to 91400). A new, fully enclosed, and heavily armored boxy
casemate superstructure was built on the chassis of the
Sturmgeschütz III. Its design was based on Stug III Ausf B’s chassis, while production models on Stug III Ausf E (12) and F/8′s (12) chassis.
It was armed with 150mm L/11.4 heavy infantry gun. It mounted the improved sIG 33/1 infantry gun, offset to the right side, for which 30 rounds were carried. It could only traverse 3° left and right, elevate 25°, and depress 6°. A MG 34 machine-gun was fitted in a ball mount to the right of the main gun with 600 rounds. Its traverse limits were 15° left and 20° right, and it could elevate 20° and depress 10°.
Storage space allowed only 30 of 150mm rounds and 600 rounds for MG34 to be carried inside the vehicle. Stug 33s were operated by the crew of 5 and were used exclusively on the Eastern Front. 12 of 24 Stug 33s produced were used in fighting in Stalingrad with Sturmgeschutz Abteilung 177 and 244, where they were all lost. The other 12 were used by Sturm-Infanteriegeschutz-Batterie Lehr Battalion XVII (training battalion) and then with 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.
Of the five remaining in September 1944, one vehicle survives at the Kubinka NIIBT Research Collection at Russia.

Most of the shells used by the sIG 33 were unexceptional in design, but the
Stielgranate 42 was different in fundamental ways from ordinary shells. The driving rod was loaded into the muzzle so that the finned projectile remained in front of, and outside, the barrel entirely. A special charge was loaded and would propel the projectile about 1,000 metres (1,100 yd). At about 150 metres (160 yd) distance, the driving rod would separate from the projectile.
The primary purpose of the Stielgranate 42 was the demolition of concrete fortifications and for the clearing of minefields and barbed wire. Unlike the Stielgranate 41 it was not a
shaped charge anti-tank weapon. In an emergency, the Stielgranate 42 could be used in an
anti-tank role to great effect but due to its short range and poor accuracy the gun crew would be dangerously exposed to enemy fire.
In summary, this would be an excellent fun addition to the German Ground Tree. Halfway between a Sturmpanzer and a Stug, it sounds so much fun. Almost the same gun as the Sturmpanzer, but actually slightly upgraded. The turret is fully enclosed, unlike the Sturmpanzer. Not as compact as a Stug, but still great 80mm of frontal armor. I'd have to put it somewhere between 2.3-3.3. At least 2.3, because, on paper, it is better than the Sturmpanzer in every way, but I can't see it any higher than 3.3, cause I can't see it being much more combat effective than a Stuh 42.. (I'm looking at you Brummbar at 4.7 for no reason.) Finally, to really make the Sig33B really stand out from the Sturmpanzer II, I would love for it to get a limited supply, their choice, of Stielgranate 42 in battle. Kinda like ATGMs on some mbts late game, it would only have a small supply for balance reasons. I think a nice donkey kick from 27kgs of TNTe, would be a fun game mechanic if you ask me. And, if anyone complains about numbers, the last surviving Sig33B is in Kubinka in Russia, so someone can drive over there to measure anything for themselves.
Well, this was fun. And, before anyone asks, yes this has been asked for before, but it has never made it on the list, so I'm trying, hopefully, one last time to get this beauty on there. Hopefully others will want this as much as I do! Cheers!!
