Purifier Squad

During the Declare Battle Formations step, if every model in a unit has this ability, you can set it up in Reserves instead of setting it up on the battlefield. If you do, in the Reinforcements step of one of your Movement phases you can set up this unit anywhere on the battlefield that is more than 9" horizontally away from all enemy models.

If a unit with the Deep Strike ability arrives from Strategic Reserves, the controlling player can choose for that unit to be set up either using the rules for Strategic Reserves or using the Deep Strike ability.

If your Army Faction is **^^Grey Knights^^**, at the end of your opponent’s Fight phase, you can select a number of units from your army that are on the battlefield (excluding units that are within Engagement Range of one or more enemy units), providing every model in those units has this ability. The maximum number of units you can select depends on the battle size, as follows:

Incursion - Up to 2 units
Strike Force - Up to 3 units
Onslaught - Up to 4 units

Once you have made your selections, remove those units from the battlefield and place them into Strategic Reserves.
