It is as Flamingknives described.
I am sure there is a call for 2 IL-2's to attack ONCE. But I was bombed 3 times, missled 3 times and strafed (actually more than 3 times as each attack includes multiple strafes).
I have CMBB Special Edition that I patched with the latest from Battlefront.com.
I have not seen this bug with other reinforcements that the AI gets during a scenario, only with aircraft.
If no one else has ever had this happen, then it must be something pecular to my program, which must mean something happened during the patch, etc. Sounds like I should reload and see what happens.
