The Space Marines are the Imperium's finest protectors.  They are the line that stands between the survival of the Imperium, and the darkness that waits to consume it.  They are the Sons of the Emperor, the ultimate soldiers.  And yet, so little is known about them.

There are a thousand chapters of Space Marines.

These are but a few of their number.

Special thanks go out to Richard Walter, Chris Valera, Robert Engvall, Michael Earley, Captain Stern, and any whom we may have forgotten, for helping us to get this information together in one place.
