Was so:
Enter ' Tornado '-> ' S-300 ' strikes with damage = 250 points --> another rocket launcher ' S-300 ' (missed is properly that they have at the same time shot) --> ' Tornado ' move 1 hex --> Rocket launcher * 1 S-300 ' launch one more rocket --> ' Tornado ' damage 200 point (total 450 point) --> ' Tornado ' flame and down.
Now mass attacks of the Air Forces are very effective are a problem.
The first aircraft take away to themselves all AA-fire, rescueing that the others.
If it is possible, it is necessary for correcting somehow.
By the way, with helicopter is not present such: they at once destroy at sufficient received damage (there is no extra expense ammo at AA-unit).
To make as for aircraft vs AA-unit.
