The crest of House Kurita is painted on each BattleMech's left shoulder, with the color of the dragon changing for each regiment. The symbol of the regimental division, a blazing sword, appears on every 'Mech's back and on the front of the right leg. The Kurita dragon in the unit's insignia is colored a bright jade green.
