  APOCALYPSE
  The crews of Predator Battle Tanks are the unsung heroes
  of the Space Marine armies. It is they who neutralise the
  Titans and traitor war machines that would otherwise
  gouge huge holes in the Astartes ranks. It is they who
  breach the impenetrable fortresses of the foe, allowing
  their comrades to strike deep into the heart of the enemy
  force, and it is they who scythe down the elite of the
  enemy reinforcements when their battle brethren are
  outnumbered almost beyond countenance. Though it is
  easy to appreciate the sheer scale of destruction a whole
  squadron of battle tanks can achieve, few truly realise the
  precision with which they enact their role.
  When the Space Marines mass for war they collate as much
  intelligence as they can about their target. Guided by the
  ancient tenets of the Codex Astartes, the leaders of each
  strike force give careful thought to how best to engage and
  destroy each element of their foe’s forces. Predator battle
  tanks, bearing the optimum configuration for the
  destruction of a certain type of enemy, are eminently suited
  to particular roles in this battle plan. As a result Predators
  of similar or even identical configurations are often pooled
  into Assassin class squadrons, tasked with the destruction
  of a single enemy unit above all others. They are supplied
  with as much intelligence and tactical guidance as possible
  concerning their target, and fine-tune their weapons
  systems in a manner to best utilise this knowledge. Though
  they see it as no more than the enactment of their
  Emperor-given duty, a Predator crewman would rather die
  than see his allotted quarry escape his battle tank’s wrath.
  PREDATOR ASSASSIN SQUADRON
  POINTS: 50 + MODELS
  FORMATION:
  3+ Predator Annihilators
  OR
  3+ Predator Destructors
  One Predator must be designated as the command tank.
  SPECIAL RULES
  Strike Force: All tanks in the squadron must be deployed within 6” of the command tank or, if coming on from reserve, they
  must enter the table within 6” of the point entered by the command tank.
  Target Acquired: A Predator Assassin Squadron is tasked with the destruction of a single entity, war machine or squad, and
  makes its destruction a priority above all else. Declare an enemy unit before the battle begins to be the Predators’ target. The
  Predators in the Assassin Squadron may not fire at any other target until their nominated target is destroyed. If a Predator in the
  Assassin Squadron is within 6” of the command tank when they are firing at their nominated target, all failed To-Hit rolls made by
  the squadron may be re-rolled.

  ‘Furious Vengeance’
  ‘Consummate Force’
  ‘Boundless Hatred’
  Over the last century of war in the
  annals of Imperial history there have
  only been three recorded instances of
  an Assassin class Predator Squadron
  failing to destroy its allotted target.
  Two of these were during combats
  fought within the Eye of Terror, where
  physics itself is the plaything of the
  Chaos Gods. The third was during the
  War of Quile’s Folly, where a
  premature declaration of Exterminatus
  ensured that not only the squadron’s
  target was destroyed, but also an
  entire Battle Company of Mantis
  Warriors and six hundred thousand of
  their Valhallan allies.
