I imagine that the not-too-distant future of close air support is drones with guns and rockets. These could potentially be operated by soldiers on or near the front lines. It's not too much of a stretch to imagine a soldier with a tablet tapping on things for the drone to shoot at.

Not needing a pilot could make them smaller, cheaper, and able to enter (and remain in) dangerous areas in a way a helicopter or plane never could.

This seems like something the Army could operate themselves.
