PDS fire

After the active player has finished moving his ships into the activated system (and after any Space Mines rolls), all enemy PDS in range may fire at the active player's fleet. For every "hit," the activating player must assign a hit to his fleet.

After enemy PDS units have fired, any PDS in range owned by the active player may then fire at enemy ships in the activated system.

Note that when firing your PDS units during another player's activation, you may only fire at the units controlled by the activating player. It is thus not possible to draw third party PDS fire at an enemy fleet by simply activating its system from afar. For more details on PDS units.
