Sent to backers of the 2015 Kickstarter campaign for Quartermaster General: Air Marshal. Details on this card: You may remove an Air Force from the board at the beginning of your Supply Step to prevent an unsupplied Army or Navy from being removed this turn. Game designer notes: (First FAQ - No, the Air Force does not have to be supplied.) I'd expect to see this rule used about once per game, Can allow for some strategies that have hitherto been a bit to dependent on supply. Can vastly decrease the impact of supply in certain situations. (Second FAQ - an Air Force can only save one piece; it doesn't put a piece back in supply, to supply other pieces.) Of course the rule is optional, as are all the "tiled" rules.
