Path of the Shogun

From publisher blurb:

Barbarians who follow the Path of the Shogun use the same burning rage they harbor within to motivate and inspire their allies. A commanding general who leads from the front, these barbarians instill both awe and fear on the war fields as their combat decrees help direct the battle towards a favorable outcome. Most who earn the title of Shogun are master tacticians who have spent years studying war tactics. Combining this skill in warfare with their natural ability to draw strength from their primal ferocity makes fighting alongside a path of the shogun an invigorating experience.
