As Choker mentions, an NOE raid is very effective with a few people, and is a very quick way to capture a field.
First, pick a field with no activity at it. You won't succeed if there are defenders already there.
Sneak in as a group. Stay low, under radar, until about 5 miles out, when you can zoom for a little altitude. The goon should stay low. When close have the goon loiter outside the town a few miles while everyone else rushes in and swarms the town. It's best if he loiters in an out-of-the-way area, not directly in line between the two fields. Kill the town guns first, then level the town. When you have it down except for just a few buildings, call the goon in so he can arrive as the last buildings get leveled.
Timing is important, any delay in getting the goon in can mean defenders lifting.
GV's will not be an issue. They can't get to the town in time if you do this right. Ignore base ack too, but make sure the goon doesn't fly over/through it.
If you have an extra guy, he can fly a figter to defend against a lifter or two. Or you can fly planes that will do duty as JABO's and then as fighters which can also strafe the town. F4U's, or P47's.
Defenders lifting? Action getting to hot? Did you take too long and attract too much attention? Go try again at a different field. This option works very well if a friendly or two will head towards the initial target. This guy is a decoy, and his dar-bar will convince the defenders you'll all be on the way back. Meanwhile, you've found another "back door" to sneak into.
