Dark Angels - Chapter Combat Doctrine: The Dark Angels follow the standard combat doctrine of the Codex Astartes for the most part, but their dogged resistance against overwhelming odds is legendary. The Dark Angels will stubbornly stand their ground in combat, refusing to give ground to the enemy, even if it is tactically beneficial to do so.Though the Dark Angels have spent nearly ten millennia hunting the Fallen, the great majority of their battles have nothing to do with their heretical forebears.As loyal Space Marines, the sons of the Lion deploy to defeat the enemies of the Imperium as would any Space Marine Chapter.Nevertheless, each battle-brother is vigilant for signs of sedition on every battlefield. To most of the Dark Angels this is simply a part of their loyalty to the Emperor. To those of the Inner Circle, anything found could be an essential clue in the hunt for the Fallen Angels.This is because the primary driving force of the Chapter is the hunt and capture of the remaining Fallen. Only by forcing every single one to repent do the Dark Angels believe they can restore their honour. If a member of the Fallen or someone who may know of the location of one is present on the battlefield, the Dark Angels will ignore their objective and do all in their power to capture this individual.Everything else is second to the capture of a Fallen Angel, including any other human life. It is not unknown for Dark Angels to fire upon friendly targets in order to prevent them from discovering the secret of the Fallen. Those friendly units that survive are often taken to The Rock to be turned into Servitors, to silence them forever.The Dark Angels are also notoriously intolerant of non-Humans and mutants, even those like Squats, Ogryns or Ratlings who are considered benevolent by the Imperium of Man. They are also highly mistrustful of the Imperial Inquisition, and will refuse to fight alongside any force that incorporates members of the Inquisition, or non-Human soldiers, except in the most dire of circumstances. This is due to the fact that they do not want the Inquisition investigating the Chapter or discovering its dark secrets.With the exception of the Deathwing and Ravenwing companies, the Dark Angels follow standard Space Marine combat and organisational doctrine as written in the Codex Astartes. Tactical flexibility, rapid deployment, and combined arms are key components of their strategies.In the same vein as their father, Dark Angels officers are expert tacticians and specialists, and have been quick to capitalise on the skills of the Primaris Space Marines and the particular capabilities of their different squad types.New specialised formations have been developed to work alongside ancient patterns such as the Hammer of Caliban and Scout Recon Stalker Strike.Caliban's Reach is but one example, which combines the immense firepower of Hellblasters and Devastator Centurion Squads to incredible effect.The advanced infiltration and reconnaissance skills all Primaris Space Marines learn as a part of their training in Vanguard Marine squads is of great value to a Chapter seeking hidden foes whilst keeping secrets of its own.The omniscramblers of Infiltrator Squads can severely disrupt enemy communications, enabling Ravenwing squadrons to strike without the possibility of their quarry being warned.The Divinator-class auspexes and transpectral combat visors of Incursor Squads collect data from battlefields that previously would have been almost impossible to extract, and yield new intelligence for the Inner Circle to act upon without the Vanguard Space Marines' knowledge.
