Ultramarines
In the Warhammer 40,000 universe, the Ultramarines are considered to be one of the greatest of all the Adeptus Astartes Chapters in the Imperium of Man, almost single handedly holding the Imperium together after the Horus Heresy. Highly disciplined and courageous warriors, the Ultramarines have remained true to the teachings of their Primarch Roboute Guilliman for ten thousand years.
"Ultramarines" is a nod to both their standing among Adeptus Astartes chapters, as well as the overall colour scheme of the army; which also lends its name to one of the main paint colours sold by Games Workshop. They are loosely themed upon Ancient Rome, as exemplified in their names and their strict adherence to the Codex Astartes.
