Range And Arc

First, determine the range between the two starships (counted in hexes) and the arc of attack. For every range increment beyond the first, the gunnery check takes a cumulative –2 penalty. The attacking starship can fire a weapon against only ships in the same arc as that weapon; see the diagram on page 318. If the targeted starship is in a hex that lies in two arcs (the shaded hexes in the diagram), the gunner decides which arc’s weapons target it; it can’t be targeted by weapons in two arcs.
