Assault guns incoming! Don't let them fire on our base!
- Kowalski, The Grande Finale!

The Soviet ISU-122 (Istrebitelnaja Samokhodnaya Ustanovka) heavy assault gun was armed with an 122mm gun that was able to fire enormous explosive shells at far greater ranges than its foreign equivalents. It was roughly equivalent to a 75mm field gun, but five times more devastating. The ISU-122 can quickly pulverize any building or unarmored units in spite of its slow rate of fire. Heavily armored, the ISU-122 can escort infantry, even under fire from light anti-tank guns.

History

A prototype of the ISU-122 (in Cyrillic ИСУ-122) heavy self-propelled gun was built at the Chelyabinsk Kirov Plant, (Chelyabinskiy Kirovskiy Zavod (ChKZ), Chelyabinsk, Russia), in December 1943. The design shared the chassis of the ISU-152 self-propelled gun and differed only in armament, having an A-19S 121.92-mm gun as its main weapon instead of the ISU-152's ML-20S gun-howitzer. Towed versions of these guns used the same carriage: 52-L-504A (Russian designation 52-Л-504А), so installation of an A-19 instead of an ML-20 gun was not a difficult task. After completing development of the ISU-152, ChKZ engineers mounted the A-19 gun on the ISU-152 chassis to create "Object 242" — the first ISU-122 prototype. It was successfully tested but not immediately launched into mass production.

Strategy and Tactics

These assault guns can murder infantry in campaign (on both sides) and can do serious damage to vehicles and buildings. ISU-122s should be utilized in numbers of 4 or more and supported by artillery, tanks, and aerial recon. When attacking, concentrate all the assault guns on one target, and then blast away.

Be careful in case infantry ambush them from the trees or cities. Also, they are particularly vulnerable to air assault.
