So my experience so far with RB-40E (for AI), is that the AI need to be pretty high (400m ASL) to get all their missiles off before they close the distance and get frazzled(they star trying to make repeated runs but never shoot).
Haven't had any luck with the BK90 pattern modes(Wide, Long, or Compact). I've tried several different scenarios.
CAS with search and engage group,
Ground Attack(Bombing. Auto weapon select, Auto release
Ground Attack(Bombing, Cruise-missile, One release
Ground Attack(Bombing, Cruise-missile, One release, Attack From 180
No joy on any pattern selection. All the above test were on a long road bound convoy. all test that achieved a launch impacted with the default square pattern.
