I wonder if it would be better to have a 3-barrelled 7.62mm Gatling and a conventional light autocannon or even a grenade machine gun. It would open up the range of viable targets and allow for the successful engagement of infantry and light AFVs.



(The primary problem with the default minigun armament for the Cadillac-Gage V100 was that its ammunition consumption was rather high. Aircraft can simply flee if they run out of ammo, ground vehicles aren't so lucky.)
