Well i think it is not a best choice of showing AI,cuz i never experienced self targeting.
I think good idea will be - you cant shoot ,AI will do it for you.But u can upgrade it as times goes on.So u can make it more accurate,more powerful or more fast shooting for ex.Or make it moves on some trajectory to closest enemy and you do shooting youself? In current state i dont even understand a point to use AI in this game.Dont be mad at me,its just my opinion,
