I was thinking that a stationary manned turret would be great to have. Maybe a maximum of 2 (or 4?) on a map. Give it 360 horizontal rotation and able to shoot from straight up to down at a good angle. The jets need something to balance them since it takes quite a lot of fire from current weapons to destroy one while they can tear up the enemy for quite a while. Allow maybe 2 shots from the turret to destroy a jet (or ground vehicle) but with a low rate of fire so it's not exactly OP. Also make them so the map creator can place them on the ground or on a tower.
Just a thought.
