Bombardier3

A ship with this keyword printed on its deckplate card has a special bombardier cannon that has a printed rank but is not associated with a mast. The special cannon cannot be eliminated, cannot be targeted by enemy effects, and cannot be assigned equipment. If the cannon roll for the special cannon is a 1 it jams and cannot be used again until the ship is given a repair action specifically to fix it. After placing ships at your home island but before the game begins, choose whether the special cannon will be an artillery cannon (use the artillery piece) or a flamestrike cannon (use the flame piece). This choice cannot be changed after the game has begun. The artillery cannon has the Extended Range keyword. The flamestrike cannon has a range of S (you may measure using the S-length flame piece); when it hits, replace one of the target's masts with a fire mast.
