can you explain this line, "if a formation marker isnt pulled, its owner keeps all but one end turn marker in his possession when the formation and end turn markers are return to the cup."End Turn markers. The ones with national flags on them. Usually there are two in the cup with the formation chits. When the second one is drawn, the turn ends, regardless of which formations have activated. There may be 3 of them.
keep all of what?
If you never get an activated formation in a game turn, you keep all but one (1 or 2, therefore) of the end turn markers until such a time in the next game turn that the first of your formation chits is drawn. You then add the chit or chits you've been holding to the draw cup, allowing the current turn to end normally, and play that formation.
