Ooops!
Turned the sound on and listened again....
The 7.62 minigun is first, then 30mm, then a coupla 2.75 rockets.
Curious, the minigun at around 20 seconds into it seems to be different than what I hear at 43 seconds. The latter sounds like it has a higher rate of fire. Maybe it's just the accoustics. Definately wouldn't want to be on the receiving of any of it!.
