Plasma mortar
From Halopedia, the Halo wiki
Exclusively outfitted on Wraiths and Brute Wraiths, the Plasma mortar fires huge balls of slowly moving superheated plasma with a large explosion radius and slow rate of fire. It is extremely powerful and usually kills in a single hit.
It uses indirect fire, meaning that it can be fired just about anywhere on a battlefield without having to worry about obstructions such as hills.
A giant stationary plasma mortar was seen destroying buildings in the Halo 2 E3 Demo video. Sergeant Banks called in an airstrike and a group of Longsword fighters flew in and destroyed it.
