(Rule)Description: At the end of your opponent's turn, you can select a number of NECRONS units from your army (excluding units that are within Engagement Range of one or more enemy units). The maximum number of units you can select depends on the battle size, as follows:
Incursion - Up to 1 unit.
Strike Force - Up to 2 units
Onslaught - Up to 3 units
Once you have made your selection, remove those units from the battlefield and place them into Strategic Reserves.
