• Each time this unit Advances, until the start of your next turn, models in this unit have a 4+ invulnerable save against ranged attacks.

If this unit has the Grim Resolve Chapter Tactic, or it has the Inheritors of the Primarch Successor tactic and it is using the Chapter Tactic of the Dark Angels, then:
