Hello

Supposing i wanted to do a map with four players, but i wanted to add NPC's, in fairly large forces. I'm hoping to learn how to make these NPC's fairly challenging; i don't expect to make them have detailed, complex bases, of course, but i'm also not satasfied by putting Ferengi and Breen ships in random spots... Is there any way of "scripting" them, to move in a tactically sound manner?
So far, i can get them to delay attacking the PC's en masse, but eventually they do swarm the PC's bases at seemingly random moments... which leaves the points i intended them to guard, unguarded.
My short term solution has been to set the groups of NPC's into different fleets, so that certain groups will fire on other groups of NPCs; thus giving the PC's a small edge in early-game battles, but this isn't really the long-term plan i hoped for...
Now, i've noticed that under the "Map Dialogue" screen, there's an option to name a "Start Location" as a "Type: AI Mission."
Does anyone know what AI Mission means? I'll be doing some experimenting to try and figure it out myself, but if anyone has some insights or advice and such, i'd appreciate some more knowledgable assistance

Thanks for your time.
