選騎士之法
The Method of Selecting Cavalry Officers
武王問太公曰：「選騎士奈何？」太公曰：「選騎士之法：取年四十以下，長七尺五寸以上，壯健捷疾，超絕倫等，能馳騎彀射，前後左右，周旋進退，越溝塹，登丘陵，冒險阻，絕大澤，馳強敵，亂大眾者，名曰武騎之士，不可不厚也。」
King Wu asked Taigong: "How should cavalry officers be selected?" Taigong said: "The method for selecting cavalry officers: take men under forty years of age, seven feet five inches or taller, who are robust, agile, and swift, surpassing all their peers. They must be able to gallop on horseback while drawing and shooting a bow in all directions — front, rear, left, and right — maneuvering and advancing and retreating freely, leaping across ditches and moats, climbing hills and ridges, braving dangerous obstacles, crossing great marshes, charging strong enemies, and throwing large formations into disorder. Such men are called Martial Cavalry Warriors — they must be generously rewarded."
