downer pretty much has it completely covered.

As a GM, I'd rule in an RPG that a CAG type would be responsible for the overall mission planning. The execution would rely on the individual pilots, so the CAG wouldn't add anything.

Now, for a Mass Combats type event, or in a large scale combat game of any type (minis, forex), the CAGs command rating could invoke a positive or negative modifiers to the success of the mission.

Frankly, in a fighter furball, the CAGs ability to command is close to nil, beyond a general decision to withdraw. Maybe not even that.
