Here's  an  easy  way  to create a British fighter ace. Using the
mission  builder  create  a mission with six BF-109s on one runway and
six  on another runway nearby but only to thell them where to take off
and  land  and  don't  give them anywhere to fly to. Fly in a Spitfire
MkII  and start the mission near the runways. Strafe the planes on the
ground.  Destroy  them  all.  Return  to  base  and you should get 152
points. Repeat this milrun mission 10 times and you get all the medals
and should be promoted to Group Captain.
