@Parakitor Could this be what we ve been looking for; under page 4 of the rules reference.
Firing Arcs
A ship’s firing arcs include all shaded arcs on the ship’s ship token plus all
? arcs, if any.
Cloud this mean that the shaded arc on the ships base is considered range 0 inside the arc for that ship?
I understand that an object "under" the base is not in arc, but that does not cover the base itself.
