The M638 autocannon is an aircraft-mounted gun in service with the United Nations Space Command.[1][2]

Design details[edit]

The M638 autocannon is used as a chin-mounted gun on the UH-144 Falcon. 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 Shade turrets. 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.

Though this weapon is capable of dealing with more heavily armored targets, destroying vehicles such as Phantoms and Wraiths to a lesser extent requires prolonged fire on target, and if a Falcon is firing from stationary position they become vulnerable to return fire from such enemies. Though powerful enough to take down larger targets with concentrated fire, most enemy vehicles have exposed drivers or gunners that if take out can often disable and vehicles or leave it almost defenseless against airborne threats.
