Use TacEdit to add squadrons to the campaign of your choice.
How To... I edited the standard Rolling Fire (removed all the default F16/F15/F5 etc) to include the Sufa and HAF F16D, the Kfir, both Viggens and the Grippen, the F4F and MIG29G, and RAF and Luftwaffe Typhoons and Tornados. Rockin'!!!!
PM me if you want the campaign file.
