uhoh, I just attemped your first scenario (Abkhazia), but was shot down before I got to do much. From what I saw, however, it was fairly impressive, a lot going on all around you. One critique, however:
***SPOILER***
I like how a pair of MiG-25's were scrambled for air support. I was confused, however, by why it was taking them so long to reach the battle. Then I saw that they were flying all the way at 500kmh (and at about 10 degrees AoA, struggling comically to maintain altitude at such low speed). Perhaps 1000kmh-1500kmh would be more appropriate?
