The Legion Rapier Weapons Battery was siege warfare distilled to its patient essence, and the Iron Warriors deployed these crewed weapon-carriages in disciplined lines that turned any position they held into a killing field. Whether mounting the arcing quad launcher, the armour-slaying laser destroyer, or the searing power of a graviton cannon, each Rapier was dug in and ranged with the meticulous care that defined Perturabo's Legion, its carriage anchoring a firebase that ground the enemy down shot by measured shot. The IV Legion prized such weapons for their remorseless efficiency — no glory, no risk beyond the necessary, only the steady arithmetic of attrition tallied in enemy dead. Emplaced amid ferrocrete and razor-wire, tended by crews as unglamorous and unbreakable as the guns themselves, the Rapier batteries embodied the Iron Warriors' cold creed: that a war is won not by heroics, but by the patient application of overwhelming, calculated force.
