Usage
This is a truly wonderful general-purpose weapon. It can function on the front line with tanks, using its gun at close range to knock out enemy armor. It can hang back when the tanks advance, using its long-range cabapilites while staying out of danger. And it can also stay in the rear with the long range artillery, functioning like a  howitzer.
 * It lacks a turret, so Immobilization will severly limit is usefulness. It also lacks a machine gun, so it requires protection from infantry. Small storage space for large shells means it can't hold much ammo, so it relys on  trucks to remain in combat.

Usage
This is a truly monstrous weapon. It is the same as the ISU-122, except the cannon size has been increased by 30 mm. This makes all the difference. One shot can take out a Panther, and it has all of the benefits and drawbacks of the ISU-122. The shells are so large that only 20 can be stored at a time, so it is very dependent on supply vehicles for ammo. The range is also smaller, but by an insignificant amount in random missions.
