Centurion - Centurion Assault Squads: Into the storm of battle march the Assault Centurions, servos whining in their mighty armour, rubble crunching beneath their heavy tread. Encased in their exoskeletal warsuits, these hulking close support assault specialists are protected from all but the most overwhelming enemy firepower. Even a direct hit from heavy artillery will do little more than stagger a Centurion, and small arms fire patters from their armoured hides like hail.Centurion Assault Squads excel at storming enemy fortifications and advancing through the broken and crumbling terrain of an embattled city. They eschew long-ranged weapons completely, favouring close-range firearms and Flamers that they use for flushing enemies from cover. Instead of heavy guns, they wield Siege Drills -- heavy-duty tools of destruction that can swiftly shatter a building to rubble, tear a breach in a strong point's adamantium-reinforced walls or reduce a living opponent to a bloody mass of broken bone.Striding toward the foe, the Assault Centurions rake their enemies with bolt shells and fiery blasts. Barricades are smashed down with contemptuous ease, and as the enemy's fortress walls loom, the Centurions' Siege Drills roar to life. These weapons are capable of reducing enemy warriors to a flesh-and-blood blizzard with a single blow, and can make short work of even the thickest ferrocrete bulwarks. In moments, the Assault Centurions force a breach, allowing their brothers to pour in around them as they stride into the heart of the enemy's stronghold like conquering kings.Assault Centurions are normally deployed in fortified battle zones where sight lines are too crowded to bring siege tanks to bear, and routes of advance too constrictive to deploy an Ironclad Dreadnought. Under such circumstances, Assault Centurions form the vanguard of the attack, using their breaching tools to tear through any obstacles in their path, while drawing the defenders' fire away from the Tactical Squads that follow in their wake. Once the fortress walls have been breached, the Tactical Squads spread out to secure the area. Meanwhile, the Assault Centurions engage and pulverise anything foolish enough to stand in their way.Wherever the rapid-strike tactics of the Space Marines are foiled, the heavy stride of the Centurion Assault Squads can be heard. In the bitter street fighting that took place on Skataurus, the Silver Skulls Chapter found that Centurion Assault Squads spearheading the attacks were the only way to make headway in the rubble-filled corridors that were once proud avenues.Although their indomitable advance through the hive city was subjected to numerous ambushes, nothing could stop the inexorable Centurions from continuing their slow, steady progress. Dug-in tanks and reinforced bunkers fell before the grinding Siege Drills, while massed Chaos Cultist ambushes met their end as twin-linked Flamers washed them over with waves of flames.Not surprisingly, the Imperial Fists -- masters of siege-craft -- have made extensive use of their Centurion Assault Squads, deploying them in all manner of line-breaking spearheads. The Salamanders Chapter, with their penchant for slow and steady advances, have used their Centurion Assault Squads as their hammer, but have also had some success in driving foes onto them as an immovable anvil of firepower.Centurion Assault Squads are led by a Centurion Sergeant.
