If your Army Faction is NECRONS, at the end of your Command phase, each unit from your army with this ability that is on the battlefield activates its Reanimation Protocols and reanimates D3 wounds. Each time such a unit reanimates a wound: ■ If that unit contains one or more models with fewer than their starting number of wounds remaining, select one of those models; that model regains one lost wound. ■ If all models in that unit have their starting number of wounds, but that unit is not at its Starting Strength, one destroyed model is returned to that unit with one wound remaining. Once such a unit is at its Starting Strength and all of its models have their starting number of wounds, nothing further happens.
