Then it is misrepresented - if you note the AC says out of ammo and requests continued support - perhaps that was where the 30mm and hellfire came from - an apache on the scene as well.
Nope, listen to the sound of the aircraft’s gun when it fires (which is pretty obvious when it does). A Gatling has a distinctive ripping, tearing sound where the Apache’s 30mm chain gun has a dut-dut-dut-dut sound and the rate of fire is much slower, 600-650 round per second versus 1500-4000+. The camera vehicle is an Apache.
