Presenting the "concept" of FSX as "Strategy Combat Simulator". A similar concept withBoard Strategy Games :
In this Mission, the 2 Flaks are just the 2 "pieces on the board map",
while the chance of hitting the player is defined by "dices" (RandomAction) with 25%
chance of downing player, each time he enters the attached to each Flak area (here defined
to a 900m radius). By defining these parameters (size of areas, chance of incidence, player's
hight, speed, Gs, etc) you create the FSX "Simulated Military Combat Events" as I mean it.

The right "tool" for this case, would be the A-7 with laser guided bombs to take out the
flaks from distance and then "papahoomamaoo". The successful attempt in video, was
a 50% total chance of player being hit, since I entered AA flak controled areas twice...
I was with the "lucky" 50% here...
