At what point can the positions of formations in a stack be altered?
Stacking order can be changed anytime during your turn. It is not considered movement and requires no order. It cannot be changed during combat. You cannot change stacking order when it is not your turn. Q: When using an order (or text such as Assemble) to play a stack from the hand to an objective/base, do the attachments have to be already allocated (attached) to a unit in the stack, or can you play the lot and then decided where to attach the company and leader cards? A: You can do it either way. Once the attachment is declared however, it may not be changed to a different card.
