Deathwatch

A Warhammer 40,000 faction that serves as the Chamber Militant of the Ordo Xenos branch of the Inquisition (Warhammer). Members are Space Marines recruited from various chapters, and are put through specialized and intensive training geared towards increasing their efficiency at killing the Imperium's many alien foes. Members will serve for a certain period before returning to their chapter. Their power armor is painted entirely black, save for a single pauldron that indicates what chapter they came from.
