Suggestion: Field Capture like Warbirds?

[majorfailure]

If it does not have to be capured in the same mission, then DCG can do what you want.
In DCG when one of your tank colums is near an enemy airfield, and you destroy the enemys defenses (AT-guns if present) and take out most or all of the FlaK (depending on what tank you attack the field with and if that can be killed by enemy guns) you can capture the airfield. You also need to make sure the enemy is not resupplying his field by air (cargo planes) or land (supply column). And you should of course keep enemy ground attack planes away from your precious tanks. Sidenote: Do not set the maximum virtual troop count to high in DCG, or it will take forever till you capture the airfield.
