That sounds very like one of the original IL*2 Sturmovik missions, which I remember from flying it for the soviet side. Yeah, they are pretty much aces I think (what does KI mean?), I think the 100 guy is slightly better than the other, but they both seemed to be much better than my squad mates, who typically got shot down by the 109s and 190s.
All the original game's missions are scripted. In the Forgotten Battles campaigns, missions are randomly generated, and any enemy aces that turn up are given names at the end of the mission if they were shot down (I think not names of real aces). You can tell Forgotten Battles campaigns, they have names like "*Fighter", or "*Fighter(Leningrad)" for the soviets, and "*Fighter (central)" for the axis, whereas the original Sturmovik campaigns are called "Fighter".
Have fun!
