  enemy units for each Reiver unit from your army that is within 3" of 
  that enemy unit (to a maximum of -3).’
  Shock Assault  
  Add the following ability to all datasheets (excluding Servitors

  Intervention, add 1 to the Attacks characteristic of models in this unit 
  until the end of the turn.’

  from the Tactical Reserves matched play rule.’ 
  Deathwatch – Special Issue Ammunition
  The following errata was published in a previous update, but is reprinted 
  here for your convenience:
  ‘Page 64 – Special Issue Ammunition
  Change the first paragraph of this ability to read: “When this unit fires 
  any ranged weapons from the following list, you can choose for it to 
  fire special ammunition. If you do so, the Bolter Discipline ability 
  does not apply when resolving their shots, but you instead choose 
  one kind of ammunition from the table to the right and apply the 
  corresponding modifier.”
  Designer’s Note: Note that the normal rules for Rapid Fire weapons, as 
  described in the Warhammer 40,000 core rules, continue to apply when 
  shooting a Rapid Fire weapon with special issue ammunition.’
  These rules updates are appropriate for the brutal assaults of Space 
  Marines, regardless of their organisation or allegiance. Therefore, the 
  following updates also apply to the appropriate weapons and units in 
  Codex: Grey Knights, Imperial Armour – Index: Forces of the Adeptus 
  Astartes (including the following datasheets: Relic Sicaran Omega Tank 
  Destroyer, Relic Sicaran Arcus Strike Tank, Gabriel Angelos, Carab Culln 
  the Risen, Casan Sabius), Codex: Chaos Space Marines, Codex: Thousand 
  Sons, Codex: Death Guard, and Imperial Armour – Index: Forces of Chaos. 
  Note that these updates are in addition to gaining the Bolter Discipline 
  ability, as described in a previous update. The changes are listed below.

  Increase Range to 12"
  Shock Assault  
  Add the following ability to all datasheets (excluding Servitors): 
  ‘If this unit makes a charge move, is charged or performs a Heroic 
  Intervention, add 1 to the Attacks characteristic of models in this unit

  Add the following ability to all datasheets (excluding Grey 
  Knights datasheets): 
  ‘This unit has the following abilities: And They Shall Know No Fear, 
  Bolter Discipline, Shock Assault and Combat Doctrines.’
  Designer’s Note: The Bolter Discipline ability is described in a previous 
  update, and the Shock Assault ability can be found above. Combat 
  Doctrines is a new ability that is explained in Codex: Space Marines 
  – this ability only works if every unit in your army has it, so currently 
  does nothing for units in Blood Angels, Dark Angels, Space Wolves or 
  Deathwatch armies (or for armies of any of their successor Chapters).
