Heavy plasma mortar

The heavy plasma mortar, also known as plasma mortar cannon, is a type of plasma mortar and the primary armament of the Wraith. The United Nations Space Command's Office of Naval Intelligence has typically type-classified encountered heavy plasma mortars based on the type classifications of Wraiths under the designation of Directed Energy Mortar (DEM). It is nicknamed PM, Comet, and Brimstone.

Design details
The heavy plasma mortar is extremely powerful and is one of the most powerful ground-based application of Covenant energy weapon technology. The plasma blast is typically a blue-white or red orb that is 0.91 m in diameter, which burns the air it passes. The plasma blast travel rather slowly in the air, so it can be out-maneuvered easily by a fast vehicle, including Warthogs. However, upon impact, the plasma blast obliterates everything—titanium battle plates, concrete, or flesh—within 20 m at the point of impact, all the while leaving a large crater on ground in its wake. The blast has a kill radius of 6.09 m, and damages any targets caught in a radius of 15.24 m.

Usage
The heavy plasma mortar is attached to the rear of the Wraith; the vehicle's propulsion drive can absorb almost all of its recoil. The plasma mortar's main use lies in shelling and vehicular warfare, as it can destroy heavily reinforced defenses from a long distance. However, it is also fairly effective in closer engagements, especially if in the hands of a skilled operator.
