Mortar weapon

A mortar is any weapon or class of weapon that utilizes the firing of a projectile or other device in an arc-like fashion at a target.

Traditionally, in the military, a mortar is a pipe in which a round (high explosive or not) fitted with a self-detonating charge is dropped in, and a firing mechanism at the bottom of the pipe launches the round in an arc like trajectory.

The paradox of mortar weapons is that all weapons are limited to arc-travelling projectiles, except the mortar is a classification of which that arc is incredibly profound.

The only mortars in Halo that are mentioned are of Covenant make: the two examples are the standard Wraith's gun and the Fuel Rod Gun from Halo: Combat Evolved multiplayer.
