Card Text/Abilities Edit
During setup, after the "Place Forces" step, you may discard any number of your equipped Bomb upgrade cards. Place all corresponding bomb tokens in the play area beyond Range 3 of enemy ships.
When Minefield Mapper is used, the player chooses a number of equipped Bomb Upgrade cards to discard. Each card can only be chosen once, so if a ship equipped with Extra Munitions uses Minefield Mapper to discard cards, it can choose to discard the ordnance token instead of discarding the card, but cannot choose and discard the card again.
