M638 autocannon

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

Design details
The M638 Autocannon is used as a chin-mounted gun on the UH-144 Falcon and some D77-TC Pelicans. It is employed in both anti-personnel and anti-armor roles. It fires explosive shells that can injure targets close to the impact area. The weapon is effective against both infantry targets and stationary gun emplacements like the Shade turret. It is also powerful enough to allow the aircraft to defend itself against multiple Banshees. Sustained fire from the M638 is even capable of destroying Phantom dropships.
