What arc choices do you have when attacking with a ship that has both a standard primary arc, and an auxiliary arc?
Some ships have an auxiliary firing arc identified by dotted lines printed on its ship token. These ships also have a unique primary weapon icon printed on their Ship cards. When attacking with its primary weapon, a ship with this icon may attack an enemy ship that is at Range 1–3 and inside its standard or auxiliary firing arc.
Consider a generic firespray equipped with a tactician that is next to a huge ship. The firespray is at a slight angle, so that one arc hits the huge base at range 1, while the other has to go a bit further and hits at range 2. Do I get a choice between the extra die for range 1, or the tactician stress at range 2? If not, which am I forced to use? Then, consider the same question but with a YV-666.
I've always played it as if I had a choice between the two on the firespray, but not for the YV, which isn't consistent. I'm not seeing anything in the rule book either way. Turrets specify that you measure closest point to closest point, but there's no clarifying language for auxiliary arcs.
Thanks for any input!
