One obscure possibility for the MN Corps is to advance after combat which might allow it to get to Tirane or Mostar.
True. It could go back to the reserve box if SR'd.
However if it ever gets out of Cetinje it has to be asked how it is supplied.
The Montenegrin Corp is always in supply.
14.1.5 Always in Supply: The following units are always in supply and do not need to trace supply:
• The Montenegrin, British ANA, and Turkish SN units. When operating outside the NE, ANA and the SN unit must trace supply normally.
