The Golden Lions

The Eleventh uses the standard white paint scheme of the Arcturan Guards, but they often paint part of each vehicle black (an arm, a wing, etc.) to symbolize their fellowship with the dark reaches of the Periphery.

Per FM: Lyran Alliance, page 55.

Insignia:

In contrast to the oval-shaped regimental insignia, the symbol of the entire Arcturan Guards takes the form of a green shield upon which is a large white single-bladed axe. The oval-shaped regimental insignia depicts a lion rampant before a field of stars. Per FM:Lyran Alliance, pages 54 and 55.
