Because I may be attacking infantry lists I need some punch to deal with soft targets. These SU-122s are one of the most optimal units in
Red Bear, the late-war Soviet compendium. Although they also suffer from the "Hen and Chicks" rule they have two potent characteristics. First, they can use the Soviet "volley fire" special rule. If the SU-122s remain stationary this rule allows them to re-roll to hit against any target within 16". Each SU-122 gets two shots so this is very nice indeed. Second, the guns are obr.1938 122mm howitzers. These are classified as breaktrhough guns which means that unarmored targets receive no saving throw. I'm a big fan of this unit, and evidently Team England is as well because
one of their lists has sixteen SU-122s!
