- "Dare to be Valiant"
- —Official Motto of the Imperial Xaronese Marine Legions
The Imperial Xaronese Marine Legions were infantry legions composed of sailors and spacers from the Imperial Xaronese Navy. Their main task was the protection of naval assets and orbit to surface warfare. The Marine Legions held an intense rivalry with the Imperial Xaronese Army's Spaceborne Infantry.
The genesis of the Marine Legions was the formation of the VII Maritime Legion, a legion composed entirely of sailors from the Imperial Navy, by Emperor Straxus II to augment the overstretched Imperial Army.
