Single 'Dynamic' Mission - Liberation

[Seeker]

I'm not quite sure what I'm supposed to do in this mission, I've tried it 3 or 4 times now.

The first time I just followed the waypoints, the Anson's appeared but got shot up on the runway

I've tried leaving it on auto pilot, but the Ansons rarely turn up

One time there was a seemingly endless supply of 110's appearing.

And of course the AI wingmen are bloody useless

Do you want to us to attack enemy armour in a Spit II?
