Playing Home Front from the Return to Hoth campaign. The red deployment point is active, but occupied by a snowtrooper. The other two snowtroopers are ready to kill the last refugee when they activate (3 dmg already to refugee, but refugee has bonus +1 health due to boon bonus). Jann is hurt badly and needs only 3 more damage to be killed, and therefore end the game in a loss for the IP. The Rebels will activate first and only need to inflict 3 damage on Jann.
As I get to deploy before their activation, I decide to deploy a double sized unit. Since the red deployment point is occupied by a snowtrooper, I must place the new unit in the next closest spot. I choose to place the unit so that it occupies the closest square to the deployment point, but also is adjacent to Jann, which allows her to survive the next attack, since her special ability is to choose an adjacent figure to be the target of her attack if she is declared as the target. The rebel players concede defeat, because they understand that their first attack won't be enough to kill Jann and I will then kill the last refugee with my snowtrooper activation.
After this there was some sour grapes about the loss and the rebel players first made me account for every threat accumulated and spent. When this didn't work, they told me that the double sized unit needed to be rotated to occupy two spots that were both closest (rotated 90 degrees), which would mean that it would not be adjacent to Jann, and therefore she would be killed before I could kill the last refugee.
I guess I'm looking for a ruling on what happened. Is there an official FFG rule clarification that proves either way what is correct? I'm ok with losing if the rules make it so, but just want to be sure my victory was not done by abusing the rules.
I've attached photos of the recreated scenario. Before and after placement of the newly deployed figure.
Thanks!
