Guardians of a Curse
The Shin legion originally painted its BattleMechs a flat, dark green with yellow trim. The unit switched to black accents on their acceptance into the DCMS, but customarily leaves a primer gray spot on the 'Mechs' torsos in anticipation of the day when House Kurita grants the unit permission to display the Kurita dragon crest.

The Shin insignia, a black Buddha silhouette against a gold disk, appears on the upper right legs of the unit's 'Mechs. Per FM: Draconis Combine, page 110.
