The Galedon Regulars insignia is a gray-white katana set over a field composed of one blue and one black triangle. This insignia is always painted on a BattleMech's upper right leg or on the fuselage of an aerospace fighter. The 21st has no regimental insignia, considering pride in a mere symbol unworthy of warriors whose first duty is to the Dragon. However, MechWarriors display the House Kurita crest on the front torsos of their BattleMechs. Per FM: Draconis Combine, pages 59 and 66.
