Kataphron Breachers are among the most heavily augmented servitors in the arsenal of the Adeptus Mechanicus, their fragile human origins all but drowned beneath slabs of plating, tracked chassis, and integrated siege weaponry. Built for the destruction of fortifications and armour at close range, they mount torsion cannons and heavy arc-weapons that shred bunkers, tanks, and infantry with equal indifference.
Guided by the cold imperatives of the Cult Mechanicus, a phalanx of Breachers advances with grinding inevitability, absorbing punishment that would obliterate ordinary troops and answering it with overwhelming return fire. Their minds are little more than obedient doctrina wafers, wiped of fear and hesitation, leaving only the will of the Machine God's servants. Where a battle-line must be broken open, the tech-priests loose their Kataphron Breachers as a living siege ram, an iron tide that neither slows nor questions until the objective lies in smoking ruin.
