Based on the weapon used by infantry for centuries, the Mech Mortar fires a small shell in a high arc that falls onto the target. Though the Mech Mortar was created by the Terran Hegemony, by the time of the Succession Wars it had been relegated to history. Like Long Range Missile launchers, the Mech Mortar could fire on a target directly or indirectly, but LRMs proved to be more reliable, easier to aim, and could fire more projectiles at once.
With the reintroduction of the Anti-Missile System engineers revived the Mech Mortar concept. The munitions used by the mortars, though often possessing limited guidance packages, weren't destroyed by AMS systems in tests. Mortar shells also proved very adaptable, accepting several types of payloads including Anti-Personnel, Armor-Piercing, Flare, Smoke, and Semi-Guided. In addition the sheer number of mortars in use made them very cheap to produce and resupply. These benefits do not overcome the fact that the largest Mech Mortar weighs as much as an LRM-20 and takes up the same amount of space while offering less than half the salvo size and only two-thirds of the ammunition capability.
