These are mostly the same mission with different spawn points. ia=in air spawn, hv=heavy, ft=fighter, nav=naval target, vb=vehicle base target, mf=medium field target and sf=small field target. iahvftvb means a mission with in air spawn, heavy fighters and a vehicle base target. Three sets of allied fighters and 2 wingman pair of axis fighters and the naval one includes a flight of TBM's at 3000 feet if you want to try a torpedo. Craterma terrain. Using the mission arena settings should set the ack to minimum. All available for download from the server or to use in a custom arena. Note that the attached are .mis files and they have to be opened with the mission editor. Hope this will help the transition.
