35mm autocannon

The 35mm Semi-Autocannon is a Covenant Loyalist weapon mounted on the Brute Chopper which originally used Brute Spikers mounted on the sides after the chopper's recent creation.

The 35mm Autocannons are the primary offensive asset of Brute Choppers, and each Brute Chopper is mounted with four linked forward-firing 35mm autocannons.

This cannon is surprisingly powerful, and its ammunition is probably a larger form of the Spiker round, fired at a slower speed.

It most likely uses a Gast firing mechanism.
