Ultramarines - Order of Battle, 999.M41: Like most Codex Astartes-compliant Chapters, the Ultramarines are divided into 10 companies of 100 Space Marines each. Each company is led by a captain of the Ultramarines, who -- in addition to his company command -- is in charge of a particular aspect of the Chapter's logistics.Since the end of the First Tyrannic War, the elite, xenos-hunting Ultramarines Veterans known as Tyrannic War Veterans have been scattered throughout every company in the Chapter to pass on their experience and expertise in killing the Ultramarines' most hated alien foes to their greener battle-brothers.An Ultramarines Astartes' company designation is indicated by the colour of the trim of his power armour shoulder plates as dictated by the Codex Astartes.The following chart displays the company commanders and company order of battle of the Ultramarines Chapter in 999.M41 before the resurrection of Roboute Guilliman and the introduction of the Primaris Marines.Chapter CommandMarneus CalgarLord of MacraggeChapter Master of the Ultramarines27 Honour Guard1 Land Raider (Maximus)Chapter Equerries1,700 Chapter Serfs &
