There have been questions about the
nature of the retreat movement and about the
Aura of Dirge of the Mourner. Geof came and gave answers
here:
-A Retreat ends up being a Run Action with a particular trigger. Once the one-sided attack resolved, the Retreat is a Run for all intent and purposes. Technically the Russian trapper 'Traps' Order did not need to specify that a Retreating model could be targeted (since it works on Running targets), but specifying it makes sure that the Order may be used even if the target hasn't moved from base to base contact yet.
-There was a misunderstanding on the Aura of Dirge wording, namely what models end up being Immune to it. I picked the wrong interpretation when I translated it, it is now fixed in the
consolidated thread.
