Maybe helicopters could be called in for mini gun support, like a transport help comes in and when I hovers over your flare, you can direct it to watch direction you want it to point towards, and there would be a gunner on the side that shoots anything in its line of sight, but you have to point them to the target, or make them rotate around. That way the heli gunner can be useful, but if a squad leader doesn't manage it a bit every now and then, it won't be effective. That way, a squad leader will have to watch out for RPGs and stuff, and point the gunner the right way to take them out, or the heli will risk destruction.
