The White Scars, who call themselves the "Horde of Jaghatai" and were originally called the Star Hunters during the early Great Crusade, are a Loyalist Space Marine Chapter and one of the First Founding Chapters of the Adeptus Astartes.
Known and feared throughout the Imperium of Man for their highly mobile way of war, the White Scars are considered the masters of the lightning strike and hit-and-run attack and are particularly adapted to the use of the Astartes Assault Bike as their mechanical steeds and their forces contain an unusually large number of Bike Squads compared to other Chapters.
