Simple Object/Trigger help

Im having a slight problem with something very simple which I thought I knew how to work.
Does anyone know how to make it so a unit doesnt auto-aquire a target? haha Ya its a n00b question, I know..

If you dont know what im asking for just think about snipers or archery tactics. I need the unit to NOT auto attack anything that comes near it and only attack specified targets via *Attack*.

Make it so that they arent enemies until the game starts, like they arent enemies at the beginning.

OOC: Do you play AQ?

I was afraid I might hafta make them allied... *sigh* AQ? I dont think so, I may have played it though. Whats it like? errr...stand for? lol

AQ stands for Adventure Quest. But you would know if you played it. Reason I asked is cause that avvy you have is a popular sprite there.

oh.. ok

do you know of any other way to keep them from auto attacking enemies? Besides making them allies? I thought perhaps changing the Attack - Combat Aquisition range to a low number might help but it didnt..
