IMHO, the whole concept of field capture needs to go away, at least as the one and only method to "win the war." Except for a few rare historical incidents, air power never occupied territory. Rather, it made it possible for land forces to take the territory. We need to break the WB paradyme of field capture.
Divide the terrain into a good old fashion hex-grid, ala tabletop wargames. Create a dynamic ground war campaign engine such as Falcon 3.0 and 4.0 use. In those stand alone games, the progress of the ground campaign was INFLUENCED by the airwar. Air Tasking orders (ATO) are generated by the campaign engine for each side, and posted. These ATO's specify mission type and targets, including intercept of enemy strikes. Depending on how successful your side is in executing the ATO, the campaign engine shifts the "front" as time goes on. Do well, and the front will generally shift in your favor. Allow a major strike to hit your factories, or an armored thrust to roll into your lines unhindered by CAS or interdiction of second echelon forces, and your rear area will soon BE the front line.
This still allows the lone wolfs to cruise for kills, but will reward the side that accepts the tough ATO's and executes them in organized fashion.
Example: The Rooks' Air Operations Center (AOC) generates ATO-9903R, ordering a particular bridge to be captured by paratroops, in order to allow your countries armored forces to quickly forde a river and make a break out into the enemy's rear area. The Buccaneers send a message to the AOC, accepting ATO-9903R, and begin a five minute planning session. Four pilots volunteer to fly Gooney Birds. The remain 8 Buccaneers "on-duty" at this time divide into a group of two (Jabo's to take out a radar site, and clear a lane for the C-47s) and a group of six (escort for the drunks). They send out a request for any available pilots to form a scratch force to hit the nearest nme airfield to the target bridge. Their goal is to close it for at least 15 minutes, in order to allow for the troop drop and egress of the strike force.
The strike goes off like clockwork (like all Buccaneer missions

); as a result, the campaign engine adjusts the frontline in their favor. Not only does the bridge now belong to the Rooks, so does a big chunk of territory around it, including that enemy airfield supressed during the commando raid. It was "overrun" by the Rooks' armored thrust. Just a few random thoughts.
