The Hidden Hand

While a Warlord with this Trait is in Reserves, the controlling player may choose to re-roll all failed Reserves rolls and when deployed to the battlefield the Warlord and all models in any unit he has joined gain the Fleet(2) special rule. In addition, an army whose Warlord has this Trait may make an additional Reaction during the opposing player's Movement phase as long as the Warlord has not been removed as a casualty.
