The more aggressive Necron Overlords fight not on foot, but rather from the deck of a Catacomb Command Barge - an armoured, repulsor-driven skimmer. While embarked upon a Command Barge, a Necron Overlord is able to oversee the battle, ensuring that his troops are engaged with appropriate targets and that everything is going to plan. More often than not he will become bored of watching the battle and command the barge's pilot to fly him into the midst of the action, where he can launch daring attacks on unsuspecting enemy units, his warscythe decapitating his foes as he flies past.
