The wording on Autothrusters is that:
When defending, if you are beyond Range 2 or outside the attacker's firing arc, you may change 1 of your blank results to an evade result...
However, in the Rules Reference, it is noted that for secondary weapons:
Range combat bonuses do not apply during secondary weapon attacks.
Now, it's obvious that Autothrusters triggers for all out of arc turret attacks. What's less obvious is whether Autothrusters would trigger for an in-arc, but range 3 attack from a secondary weapon, such as a cannon.
To me, a reading of the rules would indicate that Autothrusters would not trigger for such an attack, but FFG has published, in Interceptors and Autothrusters that:
Autothrusters increase your ability to evade all of their out-of-arc shots. (emphasis mine)
I've tried to google an answer on this topic, and could only come up with vague interpretations, or with marketing speak that seems to be contrary to what the words on the page say.
So, which is it, would Autothruster be used to avoid a secondary weapon attack at range 3?
