Quincunx

Quincunx was a Yodotai military maneuver, which was only pulled off by well-drilled, highly-disciplined forces.

Fashion
In one of the fashions the Yodotai divided their forces into three lines–, the first line had gaps, the second line organized itself behind the gaps of the first, and the third organized itself behind the gaps of the second. That units could shift to the left and right into the gaps to create lanes, useful when charged by elephant cavalry. After engaging the first line would take the brunt of the attack, until they fell back through the gaps to the third line and the second line would come take their place at the forefront.
