I'm not sure this is a good idea.
It's probably a terrible idea, to be honest ...
But I loved using these in Jagged Alliance 2

So prepare yourself for some outrageous suggestions.
MortarHas to be dropped on the ground for 3AP.
Has to be set up using science for 10AP.
Mortar shell has to be in the active slot.
Can be fired for 8AP by using the shell on the mortar.
Chance to hit relies on either Big Guns or Traps.
Can be packed up again using science for 10AP.

Damage: 60 - 80
Range: 40 - 70
Perk: Knockback

Can't target players directly.
Since you can't actually see that far,
you'd either have to rely on good faith,
or have a spotter in view range who can direct you.
Mortar and mortar shells should be pretty heavy,
