This rule was first brought forth in 2002 by ActionJackson. The VL or Deploy rule intends to restrict deployment for both sides to areas that are connected by a Victory Location. For example, after a battle there may be a patchwork of small deployment areas far behind enemy lines. If these small patches are not connected to a Victory Location, you may not deploy troops to them. Deployment zones that are connected diagonally to a Victory Location are also considered out of bounds. The Victory Location rule must agreed to prior to starting a Grand Campaign or Operation. Only though mutual agreement can this rule be changed after the game has progressed. I have added some Photoshopped examples to demonstrate where you can and cannot deploy troops when you use the VL rule.
