Hi, I observed the same problems. Wingmen of a single flights or two flights flying around doing nothing. I give command and command - but at least flight 2 never takes any action. Its very frustrating not to accomplish the mission because my direct wingmen and me have missed the target and the other AI-pilots are flying around looking in the greens. So after the attack you rejoin a squadron that shows 50% fully armed wingmen. Another big bug is the assistance: even if the escort is very close to you they never engage in air-combat by command or by themslves if they are not attacked directly. My solution is to fly with one wingman only if possible, to destroy the targets exclusively by myself and to send home that stupid AI-wingman on reconnaissance-trips as he is literally a magnet to enemy´s interceptors and - very depressing - not to trust that he is covering my six; in most cases he did not do his duty, with or without the command.
One of the reasons why I switched over to LockOn :-/
