When flying as a wingman in a flight with and AI leader, the AI doesn't give commands like attack, orbit, go to waypoint 4, etc....  As far as I know it didn't do this without DCG either but with DCG the AI sends me a message like "What the hell? Follow the leader" whenever I vector too far off course or maneuver to engage an enemy (even when the leader is engaging the enemy).  So is there something broken here?  Is the AI supposed to issue commands with DCG?  If not what I am doing wrong?  How am I supposed to know when to break formation and attack?

Has nothing to do with DCG and its an old annoying thing in il-2! Look in the samples/speech/"service"/actors folders after this sound files and take them out, should work! But before make a safe copy of that folders!
