Seems I picked a popular model, I blame Tamiya
JSU-152:

The ISU-152 was an absolute nightmare for the Wehrmacht. Much like the SU-152, it was capable of blowing the turret off of even the Panther and Tiger, as well as blowing the casemate of the Ferdinand, and Jagdtiger wide open. It could even knock out the King Tiger! However, what made the ISU-152 inherently better than the SU-152 was its superior armor and towing power. It had three major roles – assault gun, tank destroyer, and mobile artillery, which made it one of the most versatile heavy vehicles of the war. After the war, it remained in service well until the 1970s, and some even saw some unconventional action at the Chernobyl liquidation, 1986.

The ISU-152 came about for two main reasons – the success of the SU-152, and the arrival of the IS heavy tank hull. Seeing as though the IS was an upgrade of the KV series, which the SU-152 was based on, it made perfect sense to mount the same weapons on the newer platform. This would mean that maintenance would be easier with a sort-of standardization of late war tanks. Shortly after the SU-152’s deployment, the NKTP (Ministry of Transport Machine-Building Industry) ordered design teams in Chelyabinsk, in cooperation with the Mechanized Artillery Bureau, and General F. Petrov, to design two new heavy assault guns based on the IS-2 hull on May 25th, 1943. The development for this tank was undertaken by the famous Joseph Kotin, and G.N. Moskvin as the main designer – the first prototype was ready in only a month.


Much like the ISU-122, when field guns were in short supply, the ISU-152 was able to perform preparatory shelling to help out with Red Army advances. The Soviets never had any specialized, mass-produced vehicle for this purpose, but the ISU-152 was as close as they would get for the time being. Whilst towed artillery units were given to mechanized divisions, they were vulnerable and slow to field compared to the ISU-152.


Will attempt to build the white-washed "Mockba" version, shown above.
