Their volleys can damage units quickly while a Siege Ram handles buildings Build a compact group and protect it with a screen that can intercept cavalry. Focus the same target to concentrate the extra arrows, then use Siege Rams or separate siege for structures while the Chu Ko Nu clear defenders A small group lacks the output of a mass and remains vulnerable to siege or a fast dive.
