Antaro Chronus is the most gifted of all the Ultramarines tank commanders. While most such warriors dedicate themselves to the mastery of a particular type of armoured vehicle, Chronus' abilities extend to almost any tank in the Armoury of the Adeptus Astartes. Few other commanders can match the precision of his bombardments when at the helm of a Whirlwind or a Vindicator. No living man can hope to be as coldly precise when unleashing the baleful weaponry of a mighty Predator.
