The Ryuken apply the Kurita dragon crest to their BattleMechs on the left leg just above the knee and near the exhaust ports of fighters. The Ryuken insignia is a dragon curling around a Katana sword, both drawn with rich detail. The unit’s insignia is an eight-pointed shuriken with Japanese characters near each point. Each MechWarrior, aerospace pilot, armor lance and infantry unit chooses the characters on its signature shuriken. Typically, unit members select characters that represent their ideals of courage.
