TEXT: APOCALYPSE
  With a weapons configuration suited for comparatively
  short-range firefights, the Stormlord’s primary combat role
  is that of close support to infantry assault waves. As a
  result, Stormlord tanks are a rare sight in most Imperial
  armies. Super-heavy tanks are all but irreplaceable, and only
  the boldest and most confident commanders are prepared
  to jeopardise their careers (and lives) by risking such a
  valuable war machine in the very teeth of the enemy. 
  Even so, the Stormlord’s devastating close-range firepower
  and vast transport capacity makes it highly sought after by
  the more mobile Imperial Guard regiments, such as those
  raised on Catachan, Tallarn and Tingoya. Not only can the
  Stormlord’s embarked Imperial Guard squads traverse the
  battlezone in relative safety, they can also be pressed into
  service to defend the Stormlord against waves of tank-
  hunting enemy infantry.

  OPTIONS: A Stormlord may be given the following upgrades
  from Codex: Imperial Guard: hunter-killer missile, pintle-
  mounted heavy stubber, pintle-mounted storm bolter.
  A Stormlord may replace its two side sponsons with armour
  plates, increasing its side armour to 14 at no extra cost. It may
  instead add two extra sponsons, each with one lascannon and
  one twin-linked heavy flamer or heavy bolter for +100 points.
  SPECIAL RULES:
  All Power to Weapons! The Stormlord’s commander can order
  all power from the tank’s formidable reactor to be directed to
  the main weapon. If the Stormlord does not move, it may fire
  its Vulcan mega-bolter twice in the following Shooting phase
  (at the same target or at different ones).
