Era note:
Clan Diamond Shark was known as Clan Sea Fox until 2985, and then again from 3100 forward.  For units associated with the latter era, please refer to the Clan Sea Fox Faction Page.


Insignia:

The Clan Diamond Shark insignia is displayed on all war machines in the Clan Touman. Galaxy insignias may be painted on a ‘Mech or fighter, but always lower and smaller than the Clan insignia. Warriors with at least one confirmed kill may paint shark-like teeth in an appropriate place: the nose of a fighter, cockpit of a ‘Mech, front of a vehicle or faceplate of battle armor.

Beta Galaxy insignia is a faceted shark’s head thrusting upward through a circular field.
The Pearl Skate adds six small pearls to the border of the galaxy insignia, one of which is black.  The position of the black pearl designates the Trinary.
