Cheru-pattern Tyrant

The Type-38 Anti-Aircraft Cannon, nicknamed the "Tyrant", is a type of anti-aircraft emplacement used by the Covenant. It fires extremely powerful bolts of superheated plasma at a high velocity.

Design
The T-38 AAC differs considerably from the more sleek Type-27 Anti-Aircraft Cannon. It is significantly heavier in construction, and as such is more difficult to transport and deploy, though its firepower is generally considered to made up for these disadvantages. The weapon is able to fire three bolts in a rapid succession before cooling down. Unlike the unprotected observation balconies of the Type-27 cannon, the Type-38's heavy base structure effectively doubles as an infantry fortification. The base structure has two levels, with a small command center in the ground level, with slopes leading to the second level which also serves as an observation platform.

Each time the cannon fires, a bolt of plasma is generated in the core and fired up into the gun. The gun's vulnerable pinch fusion reactor is encased in a shielded power core in the center of the base structure. The destruction of this will cause the gun to explode. Alternatively, the back of the cannon is weak, and anti-vehicle weapons such as the Scorpion's main gun or the Wraith's plasma mortar will easily penetrate it and destroy the gun. To prevent this, the Covenant Army routinely stations large amounts of infantry around the gun.
