High-yield Missile Pods were developed during the Tau Empire’s Great War of Confederation after initial setbacks were encountered fighting the Ork menace, where the sheer mass of attacking Greenskin waves and the light nature of their vehicles meant that the Heavy Rail Rifle, although deadly, could not stem the overwhelming tide of attackers. By arming XV88s with High-yield Missile Pods, the Battlesuits sacrificed range and damage for the ability to lay down faster barrages that proved more than adequate in destroying the crude scrap-armoured Ork vehicles.
