Any vehicle/aircraft/boat/ect in Aces High dies when its "pilot" is killed. Makes sense in planes, but can get a little wonky in GVs. A vehicle's "pilot" is in the driver's seat, so if you can get your lead stream down through the open turret and have a round hit the driver's head, the tank explodes. This is why Jeeps can kill Tigers; drive inside the Tiger, pour a few .50 rounds into the control panel (driver), Tiger explodes.
