Because armies in the Warring States were heavily dependent on the horse, both for transportation and for the power of the chariot, the "Wuzi" places a greater importance and focus on raising and maintaining a force of cavalry more than on maintaining infantry in its discussions of logistics. Because of the shift away from warfare fought among nobility, towards the mass mobilization of civilian armies, the "Wuzi" stresses the importance of gaining the strong support and loyalty of the common people. Because of its focus on the importance of civil administration as a necessary aid to military strength, the "Wuzi" stresses the implementation of Confucian policies designed to improve the material welfare of the people, gain their emotional support, and support their moral virtues.
