Ideas:
1. If you can manage the map, a Sri Lanka campaign, where Indian AF Hinds, Mi-8s etc were used. This campaign can only be based on choppers, so will add a new dimension, as most campaigns are based on fighters.
The campaign would also be short 20 missions max. If you dont want to sticjk with actual history, you could also extrapolate the campaign to add elements of CAP, escort and napalm.
2. Bush wars: South Africa, Angola, the works, again if you can manage the maps.
3. India Pakistan (

) 1971, where you had MiG-21 F-13s and Folland Gnats against Mirage IIIs, F 86s and the J-6.
4. If you want a really far-out campaign, you could also try a fully naval campaign, with the user in charge of a gunboat/ ship. That would be tough, but if you could manage, it would be awesome!
5. 1980s Iran Iraq, I PGW, the original Gulf war. Amazing material at
www.acig.org, lotsa common planes, real scenarios.
