|This article is about the the Black Templars unit. For other uses of Company, see Company (disambiguation).|
With the Black Templars, larger Crusades are broken down by their Marshal into Fighting Companies, led by warriors who are given the honorific of Castellan. The name "company" however does not mean that it has at least 100 marines fighting in it. Fighting Companies may even consist of only 10 marines. The individual Crusader Squads or marines and specialists (such as Techmarines and Apothecaries) in a Fighting Company will fight side by side more out of familiarity and comradeship rather than any imposed organization.
