The Locutarus Storm Squad carried the Ultramarines' doctrine of decisive tempo to its sharpest edge. Equipped with jump packs and led by a standard-bearer whose vexilla broadcast the Legion's battle-cant above the roar of war, these veteran assault troops were schooled to arrive at the exact moment a foe's cohesion began to fail. Rather than blunt slaughter, the Locutarus practised surgical aggression, descending upon command posts, gun batteries, and rallying officers to unpick an enemy's order thread by thread. Guilliman valued them as instruments of timing as much as violence, warriors who understood that a battle turned on the seizing of a single fleeting moment. Through the treachery of the Heresy their swift descents blunted many a traitor advance, buying the Legion the breathing room its shattered companies needed to reform and answer betrayal in kind.
