Astra Militarum - Super-Heavy Tanks: Each super-heavy tank is a monument to the destructive power of the Astra Militarum. They are the Emperor's undying wrath cast in steel, holy weapons with the power to obliterate anything in their path. Few commanders have earned the honour to field one of these glorious relics in battle, and fewer enemies can withstand their destructive power.The largest and most destructive weapons of the Astra Militarum are its super-heavy tanks. Powered by enormous multi-fuel engines and driven by ferociously bellicose Machine Spirits (artificial intelligence), they are remnants of the Dark Age of Technology that continue to exemplify the implacability of Mankind. The hull of a super-heavy tank is layered with plates of adamantine steel armour, and bristling from this near-impenetrable casing are a multitude of armaments. Each of these monstrous machines boasts enough firepower to eradicate entire enemy formations single-handedly, and certain patterns have even greater offensive potential, with added sponson- and hull-mounted weaponry. Ubiquitous to all variants is a colossal main gun protruding from the turret. Some of these fire ultra-explosive shells, whereas others emit beams of immolating directed energy or a superabundance of mass-reactive bolts. Regardless of their payload, these weapons are capable of bringing utter ruination to the most fearsome enemies of the Imperium.During the Great Crusade, entire regiments of super-heavy tanks were fielded in battle. The rumbling of engines rolled like thunder so that the enemies of the Imperium felt their advance long before the armoured wave broke over the horizon. Now, only a handful of Forge Worlds possess the sacred STC databases required for their construction and maintenance. As such, they cannot be deployed on every one of the Astra Militarum's many war fronts. Only in the most crucial theatres, where failure is absolutely unacceptable and the sheer weight of Guardsmen corpses has not yet won victory, are these steel behemoths unleashed upon the enemy.A single super-heavy tank is a dominant presence in an Astra Militarum battle line. As it ploughs inexorably forward it lays down a wide path of destruction. Enemy ranks shatter long before it reaches their position, and those unlucky few who are able to maintain their defensive formations are ground to paste under the slab-like plates of its tracks. To witness such merciless punishment meted out against their foes provides a huge boost of morale to nearby Astra Militarum forces. Though they face unimaginable horrors, they are given hope by the vessel of incarnate devastation that fights alongside them.The Baneblade is the most common variant of Imperial super-heavy tank. Its primary weapon -- the fearsome Baneblade Cannon -- is capable of delivering apocalyptic bombardments at a terrifying range. At close range, armoured vehicles are blasted to scrap by its hull-mounted Demolisher Cannon, and enemy infantry and xenos beasts are blown to pieces by its Autocannon and twin Heavy Bolters.Each other pattern of super-heavy tank has armaments that make it dominant in specific battlefield roles. The Banehammer is the ultimate equalizer when facing a highly mobile enemy force. The massive shells of its Tremor Cannon are primed to explode only once they have been embedded below ground. The sundering effect of their detonations makes rapid redeployment impossible. The Hellhammer and Stormsword are both designed for use in siege and urban warfare, their respective cannons making a mockery of defensive barricades. The Hellhammer also mounts a Demolisher Cannon, whereas the Stormsword's Siege Cannon alone provides reliable devastation. Similarly, the Banesword's Quake Cannon can pulverise enemy armour and reduce fortifications to rubble. The Shadowsword is equipped with one of the most fearsome primary weapons -- the dreaded Volcano Cannon -- and is capable of taking down Titans at extreme ranges. Nothing short of the most powerful energy fields can hope to stop a direct hit from its blasts. The Magma Cannon of the Doomhammer is a smaller version of the Volcano Cannon. Though it has a reduced range of fire, its compact size allows for troop transport space within the hull. The Stormlord, on the other hand, is almost entirely dedicated to troop transport, its cavernous bay capable of carrying forty Guardsmen, while its Vulcan Mega Bolter makes it particularly potent against enemy infantry.
