Any chance of improving tactical engine?

"You can also use Guard Commander to move your troops backwards and sideways, to pull enemy arrow fire where you want it (if the enemy is using Fire Closest), or even to get enemy flankers pulled into the middle of your army."

Hey, thanks for the idea, this seems really useful. I can see how the Hold/Attack pattern would be good for keeping a rein on your overeager troops.

However can you explain how to get your commander to move backwards and sideways using this technique? I would think retreat might work for moving backwards, but I am guessing that this would pull the troops off the field with you.
