Legion Fellblade

When the Imperial Fists faced a fortress even their siege train could not swiftly crack, they answered with the Legion Fellblade, a super-heavy battle tank whose scale and firepower belonged to the reckoning of a siege rather than a skirmish. Its colossal fellblade accelerator cannon could bring down a curtain wall or annihilate a strongpoint in one earth-shaking detonation, and secondary weapons swept away any defenders who survived to man the rubble. To Rogal Dorn's Legion, masters of both raising and razing the mightiest defences, the Fellblade was the ultimate siege-breaker, a weapon that turned months of grinding assault into a single decisive blow. Each was a treasured relic committed only against the most obdurate objectives, its advance heralding the collapse of walls that had defied every lesser gun. Behind its shattering barrages the disciplined companies of the VII would surge forward, storming through breaches the Fellblade had opened by main force alone.
