yup. DCG should be your first choice.
a part from the readme:
"This program can also generate single mission as well as missions for the on-line "Dogfight" and "Coop" modes (there are two "on-line" friendly campaigns available for use). Over time, the front lines will shift, airfields may be captured and recaptured and objects appear and disappear. Squadrons will transfer closer to the front as friendly ground forces advance or bug-out should the enemy break-through. Armor, truck columns, and trains will also move from city to city during missions and ships from harbor to harbor, starting the next mission at the city or harbor moved to in the previous mission. Build ups of guns and armor will also appear at the "front" and captured locations will have new defences generated.
IL-2 DCG will also track plane losses, pilot deaths, and the replacement of both, awards and promotions, as well as the destruction and replacements of moving vehicle and tank columns, trains, and ships, and static ground defenses. All in all, DCG offers IL-2 players a fully dynamic world in which to fly. "
in short: all that you destroy (or not..) has a direct influence on the next mission and the campaign outcome.
