Changes

===Belicosa pattern===

Carried on arm mounts by Mars-Alpha pattern Warlord titans. Too large and powerful to be carried by lesser vehicles or titans, it requires the plasma reactor of a mighty Warlord titan to feed its ravenous appetite for energy.{{Fn|13}}

===MkIV Phaeton pattern===

The '''Type 22-S, MkIV Volcano Cannon, Phaeton pattern''' is the Volcano cannon mounted on [[Imperial Guard]] [[Shadowsword]]s.{{Fn|1b}} Due to the immense power requirements to fire the weapon, the Shadowsword must be stationary so that the main drive can be disconnected and the generator connected in its place, allowing power to transfer to the vehicle's capacitors. Firing the weapon just once will completely drain the capacitors, again requiring the vehicle to remain stationary so that they may be recharged.{{Fn|1a}}

===MkIII Synne pattern===

{{Fn|11a}}
