Harriers would be cool but they are usually operated from aircraft carriers, too bad glest doesn't have a carry ability, then you could have the harrier land on a ship to reload, a suggestion for aircraft, unless VTOL, they could circle above the point where they should be standing instead of just hovering in one spot, kinda unrealistic, the harrier could replace the f22 but the A-10 should stay, another aircraft idea, the OV-10 bronco as a scout aircraft with a machine gun for defense, large line of sight, good to pair up with the A-10 for to keep watch of whats ahead.
