4th Federated Suns Lancers
The Lancers parade color scheme is navy blue with gold banding on the arms and legs. Gold is also used on the upper torso of the ‘Mechs and the turrets of armor units to highlight panels, resulting in a checkerboard pattern. The Fourth uses silver in place of gold, and like to paint blue flame accents so as to make the silver trim appear to be on fire.
