—Mou Gou telling his men about Rindou
The Rindou is a tactical formation used to effectively break through to an enemy's center. It relies on the movement of cavalry troops in two separate circles to draw enemy troops to the sides so the center is left vulnerable to attack. It is named for its spiral motion on the battlefield in terms of troop movements when using the move. The only known user of this formation in the series is Rin Ko.
The formation is first seen in the sixth day of battle between the forces of the Zhao general Rin Ko and Qin generals Ei Bi and Do Mon when both armies fought on the Rui Plains. It has been used by the Zhao general in his previous battles against Great General Ō Ki.
The formation has been seen performed by Wei cavalry troops as they whip up a dust storm, riding in circles as two separate units. The two circles slowly move forward, chipping away at any enemies caught on the edges. It appears to be attacking the left and right flanks of the enemy but in reality, the circular motion drives enemy forces to the sides thus weakening the center. This is followed by the troops in both circles converging on the weakened center thereby breaking through their front lines to reach an intended target which is usually an enemy general.
Strengths & WeaknessesEdit
Its strength is in its versatility, break-through power and ability to fool the enemy into making the wrong moves as most generals would defend the two sides, not knowing that they are drawing from the center troops to do so. Visually, it can confuse troops as the target is not seen until it is too late to defend and since generals are surrounded by their troops, sighting them as a target is easy for any user of this move.
The weakness is that there must be a stable target and properly trained cavalry. If an enemy general changes position constantly, the Rindou cannot effectively kill him in one swoop. Keeping the riders in sync is another issue as the Wei troops were struggling with maintaining the motion, some of them falling down if they could not keep up and being trampled by the horses.
