Heavy Mortar

The heavy mortar of the Atomic Age blurs the boundary between portable infantry support and towed artillery — a wide-bore tube on a reinforced baseplate that requires vehicle transport but delivers warheads approaching light howitzer effect. American 4.2-inch and Soviet 120mm heavy mortars could hurl shells of twelve to fifteen kilograms to ranges exceeding five kilometers, dismantling field fortifications and creating casualty zones lighter mortars could not approach. Cold War armies retained these systems for their flexibility and simpler logistics compared to towed guns. A battery in prepared positions could saturate a grid square with plunging fire faster than any comparable artillery, striking targets in defilade that flat-trajectory guns could never reach. In the game it is a devastating indirect-fire asset excelling against fortifications, bunkers, and tightly grouped formations. Its weight demands transport support; without infantry protection it is helpless against fast-moving attackers.
