The text for the Move + Activate action for the Yellow Squad reads,
Your Space Marines may move to any position in the formation (instead of just to adjacent positions).
I'm just not sure whether to shift the formation after moving the space marine or to swap positions with the space marine that already holds the target position.
When the rules explain the normal movement of space maring into adjacent positions, the text reads,
To move a Space Marine to an adjacent position, he simply picks up the Space Marine card, and switches its position with any adjacent Space Marine.
Based on that text in the rule book, I've been making the assumption that swapping positions is also what was intended for the Yellow Squad. Is that correct?
