Suppressing Fire

When you deploy it, choose how many of your ready Mercenaries and/or Gliders that aren't dispatched to exhaust, at least one, in any mix: that number is X. They stay exhausted until your next stoke phase. A crew that came on board this turn can pay it too (306.5d).

Choose an expedition on board when you deploy it, whoever launched it; without one, you can't deploy it. For the rest of this turn, your opponent can't dispatch a crew there whose hull left is X or less, checked as they dispatch; plating doesn't count. Their bigger crew, the other battles and your own crew aren't affected, and crew already dispatched there stay. It works in either player's turn. If the expedition has left the board by the time this resolves, nothing happens (703.7).
