The M638 Autocannon is an aircraft-mounted gun in service with the United Nations Space Command Defense Force.

Design Details
The M638 Autocannon is employed in both anti-personnel and anti-armor roles, and is exclusively mounted as a chin gun on the UH-144 Falcon. It fires explosive rounds that can injure targets close to the impact area. It is effective against both infantry targets and stationary gun emplacements like the Shade turret, and even allows the Falcon to hold its own against multiple Banshees. Sustained fire from an M638 is capable of destroying Phantom dropships.
