Hi
It bothered me greatly from our las regionals. Was trying to found clear answer on this but fail.
Situation:
We have tie fighter trying to shot on A-wing in debris field. Both bases are all hiden in obstacle and toucheach other.
Question:
Does debris field obstruct LoS during Tie attack and a wing counter attack?
In my opinion No (but this is my opinion-judge on tournament say Yes). For me there is unobstructed LoS (small but still)
