Each tray has four firing-arc lines used to measure a unit’s firing arc. A unit’s firing arc is the area formed by extending the firingarc lines from the two firing-arc lines on the front corners of a unit’s front rank. A firing arc extends across the entirety of the play area.
- If any part of a unit’s tray is inside a firing arc, the entire unit is treated as being inside that firing arc.
- The lines that compose the boundaries of a firing arc are treated as being inside that firing arc.
- When a unit is determining line of sight, both points by which line of sight is determined must be within that unit’s firing arc.
