Are unsupported fighters able to retreat?
I started a thread on the BGG forums ( boardgamegeek.com/article/27711294 ), but no conclusive verdict was reached.
Capacity is not checked until the end of combat. Retreats happen as part of combat.
67.7 of rules reference:
QuoteTo retreat, a player takes all of his ships in the combat and move them to an adjacent system.
49.8 of rules reference:
QuoteIf an ability moves a unit outside of the “Movement” step of a tactical action, players follow the rules specified by that ability; neither a unit’s move value nor the rules specified above apply.
This seems to indicate that unsupported fighters can retreat (capacity would then be checked in the system they retreated to), but this is a little odd from a thematic standpoint. It's not clear that this is what was intended.
