Scratch

I don't know if this is 'advanced', but it seemed advanced to me, so I posted it here.

Anyways, I'm making an Advance Wars-style game (http://uk.ds.ign.com/objects/949/949669.html) and I need help programming an AI. I'm kinda in a hurry, so uncomplicated help would be best, but, if complicated is whats needed, I'm all ears. 

The main difference that I have is that I'm not using 'squares' to move. I'm setting each unit a distance to move, and then letting the player/AI move it in any direction they wish, until it runs out of 'movement points' for that turn. Attacking is done by 'if distance to [unit] is less than [range]'. Any more questions, feel free to ask, and I'll add the answers to them here.
