This also be implemented.

   sort_units(); /* to let explorer move before other units */
   for_each_unit
   {
      while(current_unit_can_move())
      {
         think_about_best_direction(); /* could use dry_run */
         result=move();
         /* if dry_run was used before if should succeed */

         if(is_enemy_unit_near())
             if(enemy_can_be_killed()) /* is there a unit with attack>0 near */
                try_to_kill_it();
         if(is_enemy_unit_near())
             retreat();
      }
   }

The server ai is programmed in this model. So the model can be as good
as the current server ai. The code above is just a sketch. For example
if a unit can kill one of two enemy untis the code have to choose the
"right" one.
