Chapter - Post-Ultima Founding Chapter Organisation: As before, the organisation of a Space Marine Chapter in the wake of the Ultima Founding of the Primaris Space Marines comprises 1,000 Battle-Brothers. In comparison to the teeming multitudes of the Emperor's original Space Marine Legions this is few indeed, yet history has proven time and time again that such an elite gathering of martial strength can conquer star systems and even alter the fate of the galaxy itself.After the resurrection of the Primarch Roboute Guilliman in ca. 999.M41 and his restoration as the ruling Lord Commander of the Imperium, the Codex Astartes was revised for the new era that began with the birth of the Great Rift.Under the revised organisational scheme for a Space Marine Chapter the updated Codex prescribed, each of the ten companies of a Chapter still boasts one hundred warriors, led by a Captain -- a veteran of countless wars -- and often two Lieutenants as sub-company leaders. A company is still organised into ten squads of ten Space Marines, each led by a Sergeant.However, the guidelines in Guilliman's updated Codex provide for up to twenty squads of five Battle-Brothers. Furthermore, recent precepts allow for each Battle Company to be reinforced with auxiliary warriors. These additional squads are reassigned from the Reserve Companies.Of the ten companies, the 1st still consists of the Chapter's most experienced Veterans, and is therefore the most powerful. The Veterans of the 1st Company are still trained to fight in Terminator Armour. It is extremely rare for the Veteran Company to be deployed en masse -- its units normally take to the field alongside the Chapter's Battle Companies.The revised Codex Astartes decrees that the 2nd, 3rd, 4th and 5th Companies are designated Battle Companies, and generally carry the weight of a Chapter's combat duties. Battle Companies consist of at least six Battleline Squads, two Close Support Squads and two Fire Support Squads. Assault Squads, a type of Close Support Squad, may be deployed as Bike Squads or Land Speeder crews and, just as with their Fire Support brethren known as Devastators, may take to battle as Centurion warsuit pilots. Most Space Marine deployments will consist of a single Battle Company, reinforced by elements of the Veteran, Scout and Reserve Companies as needed.The Reserve Companies are entirely composed of squads of the same designation. They normally act in support of the Battle Companies and provide a source of replacements for any casualties suffered by the frontline formations. The 6th and 7th Companies are Battleline Companies, each consisting of between ten and twenty of the different types of Battleline Squads. The 6th Company also trains in the use of Assault Bikes and may be deployed entirely as Bike Squads. Similarly, squads of the 7th Company are trained to fight with Land Speeders and Stormtalons, often acting as a light vehicle reserve formation.The 8th Company is the Close Support Company, and consists of ten to twenty Close Support Squads. It is most often used in an invasion role, or 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 cannon-toting Astartes provide unparalleled fire support to their more lightly equipped comrades.The 10th Company is still made up entirely of Scout Marines -- new recruits whose physical transformation and training is incomplete. The Codex Astartes now dictates no formal size for the 10th Company, as the rate of recruitment is not fixed.All companies, except the Scout Company, maintain a fleet of Rhino, Razorback and Repulsor armoured transports. The Veteran Company also has a permanent complement of Land Raiders of different patterns and Stormraven gunships for carrying Terminators into the heart of battle. A Chapter's other armoured vehicles form a pool, maintained by the Armoury, that Captains can draw upon. Many companies also include a number of Dreadnoughts, which remain a part of the company in which they served before being interred in the cybernetic sarcophagus.Every Space Marine Chapter also includes a number of officers and specialists as before, who provide essential battlefield support, spiritual leadership, psychic capability and destructive combat prowess. These individuals are collectively known as the headquarters staff, and include Apothecaries, Chaplains, Librarians, Ancients, and Techmarines.Over all of these mighty warriors presides the Chapter Master, elevated from the greatest of the Chapter's Captains. He alone is responsible for the deeds of the Chapter, and answers directly to the Administratum. Chapter Masters may select an Honour Guard that are in addition to the company roll, although not all Chapter Masters choose to do so.
