This is my first batch of Heavy Assault Guns. At the last minute i decided to magnetize the guns. I have 8 more to do, so I'll take more pictures of that process and post a brief tutorial. I am really happy with how these guys came out! The models were quite easy to work with, and I am a huge fan of the exaggerated details on these guys.
ISU-122 From Wikipedia
The ISU-122 was used as a powerful assault gun, a self-propelled howitzer, and a long-range tank destroyer, the same as with the SU-152 and ISU-152 heavy self-propelled guns in general. However these vehicles differed in their combat use. The primary application of the ISU-122 was as a tank destroyer, while the SU/ISU-152 tended more towards the assault gun role. With the same hull as the IS-2 the ISU-122 had good armour performance but more importantly very good performance with high-explosive rounds. The 121.92-mm gun had great potential, although the gun's abilities were somewhat reduced by the available projectiles and its lack of accuracy. In 1944 the BR-471 was the sole armour-piercing round available (the Germans had armour piercing rounds also, including ballistic nose and sub-caliber variants). An improved version, the BR-471B (БР-471Б) was developed in early 1945, but was available in quantity only after World War II ended. In extremis the ISU-122 engaged enemy heavy armour with OF-471 (ОФ-471) high explosive projectiles. These shells had a mass of 25 kg, a muzzle velocity of 800 m/s, and were equipped with a 3 kg TNT charge. Mechanical shock and explosion was often enough to knock out enemy AFVs without any armour penetration.
For urban combat ISU-122's were utilized as assault guns, but with a lower efficiency in comparison to the SU/ISU-152. In general Red Army commanders viewed the ISU-122 as a good assault gun. The OF-471 projectile was powerful enough against unprotected and entrenched infantry, pillboxes, and fortified buildings. In urban combat the long barrel of the 121.92-mm cannon sometimes made maneuvering difficult.

I love the Battlefront IS-2 model. Just look at this thing in all its majesty.
ISU-152 From Wikipedia
The ISU-152 self-propelled gun combined three battle roles : heavy assault gun, heavy tank destroyer and heavy self-propelled artillery. The 152.4 mm gun used a number of powerful (shell and charge) ammunition. Some of these ammunition had a 43.56 kg high-explosive shell, or a 48.78 kg armor-piercing shell, or the heaviest of all, the 53-G-545 (53-Г-545) long range concrete-piercing ammunition with a 56 kg shell. The ISU-152 was used for infantry and tank support, and attack on fortified positions in a direct fire role, for support on the battlefield in an indirect fire role, and for fight against tanks with a direct fire.
