A.15 FIRST/FINAL FIRE: Even though Defensive First Fire occurs during the MPh and Defensive Final Fire usually occurs during the DFPh, qualifying units may fire in both without violating the general rule that no unit can fire in more than one phase per Player Turn (7.1).
EX: A 4-6-7 squad firing during the opponent’s MPh as Defensive First Fire may still fire in its own DFPh at adjacent or same-hex units as Defensive Final Fire (provided it is not already marked with a Final Fire counter [EXC: FPF; 8.31]). An AFV firing its CMG as Defensive First Fire may still fire its MA in its DFPh; if it changed its CA to fire the CMG, the appropriate Case A DRM would still apply to its MA shot (D3.51).
