The Mortar is a manned stationary siege defense mechanism which launches 1-round artillery mortar shells at any enemy that enters its 500-tile firing radius but it will not fire once the enemies have reached within 30 tiles, or can be manually set a forced target. The range indicator of mortars is not its actual range, but the size of its blind spot. It cannot fire if covered by a roof. It has a 5.8-second warmup time, a 28-second cooldown, and an 11-tile forced miss radius. Mortars explode in a 4.9-tile radius when destroyed and deal 50 damage. Loading different shells into it will produce different effects. These shells can be manually extracted from the mortar. Mortars can be set to accept different types of shell.
Mortars require a pawn each to load and fire shells. Their skills have no effect on accuracy, however pawns incapable of violence will refuse to man them. Unlike drafted colonists, mortar personnel do not relieve their position once the battle is over and must be manually unassigned, or they will become exhausted, starve, and potentially suffer a mental break. There is no way to increase mortar accuracy.
It is possible to loot mortars from siege attacks, so long as the enemy builders complete construction, by reinstalling them in your base. Pawns assigned to construction will haul them to their new location but haulers won't.

Version history
In Beta 18 the three types of mortars (Incendiary, EMP and explosive) were replaced with a single type, which fires different types of shells that achieve the same effect. In addition, two new shells are added, the firefoam shell and the antigrain warhead.
