Shield of True Belief
The Dieron Regulars disdain parade-style color schemes, preferring appropriate camouflage. When orders require parade dress, the Regulars paint their 'Mechs white with gold trim.
Per FM:Draconis Combine, page 48.
The Dieron regiments bear their district and regimental insignias proudly, along with the House Kurita dragon crest. The crest always appears on the outside of a BattleMech's right shoulder, and the district insignia of a red starburst against a setting sun appears on the right arm just below it. Regimental insignias tend to appear on a BattleMech's upper left leg. The various insignias appear in corresponding locations on other types of war machines. The insignia of the 40th Dieron is a red shield against a black and gray field. Per FM: Draconis Combine, pages 48 and 56.
