Even tho, the housing of the AA Missiles on the Cheetah could hold 2x4 Missiles it currently only Holds 2x2 and only the lower part of the Missile Case is used.
I don't know, why any Army would not use the full potential of a Vehicle, also 4 Missiles seem a bit few, and may not even be enough to sucessfully engage a Jet.

Since the Opfor AA Tank got the Same Turret, this should also affect it. {F26778}
