If I remeber right all aspects of modern combat are included although the long range artillery is "off board"
Air support had aircraft counters flying around the map with entry and exit points pre-planned, target could be laser targeted by ground units.
You could also use laser targeting with helicopters and ground units. One game I played had an infantry unit laser target a T80 and a ATGM from a hele' hovering behind a hill took the tank out. It was a blind moderated game and my opponent never knew where the shot came from.
I also believe AH produced a second game call IDF (Israeli Defence Force). Whether it was an expansion or a seperate game I don't know.
Slightly off topic of scale: Cold war central Europe would have been a good location for CMSF. All the major players are involed. Much of the equipment then is simply older version of todays stuff. I'm sure the modders out there would be able to transform such a game to anywhere in the world.
Example 1: Falklands 82-Goose Green, Historical infantry action with limited support.
Example 2: Falklands 82, as above but throw in a tank platoon for a "what if" battle.
