If the army includes a model with Hunting Call, the owner may: • Choose to roll for Ambush for units with one or more models with Pack Tactics starting from the owner's Player Turn 1 (but still at the end of step 2 of the Movement Phase Sequence), unless the owner has the first Player Turn. • Reroll Ambush rolls of 1-2 for units with one or more models with Pack Tactics. Hunting Call is in effect even if the model is Ambushing and has not arrived on the Battlefield yet.
