Hmmm, tried with various groups attacking at same time (same side and different allied sides), with SU33, F18, F15... and the Backfires are the only ones who makes sinks.
You put a great barrier with those escorts
One time a SU33 get closer, really close... 2 miles! and didn't attack.
In my opinion you have two options: simulate the attack with a damage script, or use backfires. :hmm:
