Master of the Fleet

The Master of the Fleet is that Space Marine Captain who is deemed to have the most experience and greatest skill at planning and executing void-combats. He is given command of the Chapter fleet, and essentially serves as the Chapter's fleet admiral, commanding its flagship and all other space assets when they deploy for major engagements. In rare cases, a Chapter's Master of the Fleet may not be an Astartes officer but a mortal with a long history of space combat and commanding fleet engagements, such as a former or current command officer of the Imperial Navy who has been seconded to the Chapter under ancient inter-service agreements. This Role is typically given to Captains of the 4th Company.
