When the heavy guns of the artillery batteries are otherwise occupied, it is useful for the infantry to have their own indirect-fire weapon. The 82mm And 120mm Mortars can be just as good as the bigger guns at digging infantry out of cover. Soviet mortars have built-in wheels, so the mortars can move quickly to keep up with the infantry that they are supporting. Includes three 82mm and three 120mm Teams and two Unit cards.
