Dark Angels - Remaining Chapter Companies: The remainder of the Chapter is organised along standard Codex Astartes lines. The 3rd, 4th, and 5th Companies are Battle Companies -- the backbone of the Chapter's fighting ability and the core of any prolonged campaign. In large battles, these formations generally form the centre and will be counted upon to bear the brunt of the fighting.The 6th and 7th Companies are Tactical Companies, each consisting entirely of Tactical Squads. These act as a reserve which may be used to bolster the front line, launch diversionary attacks or stem enemy flanking moves.The 8th Company consists of Assault Squads, typically equipped with Jump Packs. When deployed en masse, this company is used to storm an enemy's position -- quickly closing with a foe and engaging in close ranged or hand-to-hand combat.The 9th Company consists solely of Devastator Squads. It is the most powerfully armed company in the Chapter, and is used to bolster defence points and provide long-ranged fire support.The 10th Company consists of Scout Squads; youths who have been partially transformed into Space Marines as Neophytes but are not yet full Initiates of the Chapter. This company represents the future of the Chapter and has no formal size as the rate of recruitment operates under a wide number of variables. Those Scout Squads nearest to completing their training are assigned to strike forces. It is almost unheard of for the Scout Company to fight as a single unit.The traditional composition of the companies of the Dark Angels and their Unforgiven Successor Chapters outlined above shifted after the introduction of the Primaris Space Marines by Roboute Guilliman and the Indomitus Crusade during the Era Indomitus.The Battle Companies now consist of six Battleline Squads, two Close Support Squads and two Fire Support Squads comprised of any combination of the types of squads delineated below. Most Dark Angels deployments now consist of a single Battle Company, reinforced by elements of the Deathwing, Ravenwing, Scout and Reserve Companies as needed.The 6th to 9th Companies are Reserve Companies, entirely composed of squads of the same designation. The 6th and 7th Companies are Battleline Companies, each consisting of between ten and twenty Battleline Squads. These act as a reserve which may be used to bolster the front line, launch diversionary attacks or stem enemy flanking moves.The 8th Company is the Close Support Company, and consists of ten to twenty Close Support Squads, most often used wherever a strong hand-to-hand fighting force is needed.The 9th Company is the Fire Support Company, consisting of ten to twenty fire support squads. It is the most heavily equipped company in the Chapter, and its heavy-weapon bearing Astartes provide suppression and raw destructive power. Squads from the Reserve Companies are often attached to a Battle Company in order to bolster a given force's capabilities. In such instances, they are identified as the 11th Squad, 12th Squad and so on.The 10th Company in the new force organisation still serves its traditional role as the training ground for new battle-brothers of the Chapter, and is made up entirely of Scouts and a force of Vanguard Space Marines. Led by a Sergeant, these recruits will take to the battlefield alongside the strike forces of other companies, typically acting in a reconnaissance role. The reformed Codex Astartes dictates no formal size for the 10th Company, as the rate of recruitment is not fixed.
