I would like to sugges the Raupenschlepper Ost/3 armed with a 15 cm s.I.G. 33 L/12.
This would add one of many of the armed versions (2 cm - 15 cm) and be a fun fully tracked mid war
this quite basic vehicle would add a fun array of usabel to derpy and usable guns to the lower Brs.
It would show the need of the German army to specifically develop a vehicle for the eastern Front as well as to arm every and each vehicle possible to get more guns mobile.

The RSO was a specifically designed for the Eastern front, all tracked transport vehicle from December 1942 which was produced 1000 a year and came in 3 basic versions.

The /1 was the first standart vehicle with a fully enclosed cabin and Ottomotor.
The /2 which was the classc Open and often armored variant with a 7,5 cm Pak 40 L/46
and the /3 i am suggesting which was used in trails for a wide array of guns, including this 15 cm s.I.G. 33 L/12, furthermore the /3 as a vehicle itself was equipped with a half open simplefied cabin and a new Dieselmotor which was more powerfull and accessable as well as reliable at the cold temperatures of the eastern front.

The 15 cm s.I.G. 33 L/12 was a early developent of a 15 cm gun as light and mobile as possible to be pulled by light Halftracks/trucks or horses, accessable to the infantry and give high firepower.

However it was still quite heavy as such it wasnt the best to go to muddy ground and was often put on vehicles of many kinds, including tank chassis such as Pz I, II, III and IV.

The results of the Trails of a couple of guns are sadly lost to history (or i didnt find them)
But the only 2 versions that went into full production were the 7,5 cm Pak 40 and 2 cm Gebirgsflak 38 armed ones, the /2 and /3.
