The CV9040B and C. One of the largest guns on an IFV, with some neat tricks up the sleeve of the C Model. Note: After recording, I found a CV9040 gunner. He says the gun is actually stabilised.
Again, using Steel Beasts Pro PE, if you are/were a crewman of a vehicle modelled in the sim which I haven't covered, please reach out to me.
