The Short Supply card forces a unit to retreat to the last row on his side of the board in his section. What if, by some chance, all the hexes in the back row are filled? Does he lose that whole entire unit?
If no hexes are vacant on the edge of the battlefield, place the unit in a vacant hex one row forward of the edge. Please also note, if the unit that is being short supplied is your unit, it may not battle this turn.
