《智囊(选录)·兵智部·战车》
布阵的方法是，每军有二千五百名士兵，其中五分之一是将佐、卫兵，以及后勤补给兵，其余的两千人分别乘坐八十辆战车，排列成一个方阵形，每面都有二十辆战车，车车相连，士兵就在车与车的间隔之中行进，前排战车可以向前进攻，后排战车可以向后进攻，左右的也可以各往外推，敌人攻左右就抄他后路，随着敌人进攻的方位而防守，可以有多种多样的变化，而将领、卫兵以及后勤兵都在方阵之中，这方阵也可以随地形变化而变成圆曲状，行进的时候阵中的步兵可以再排列阵式，休兵的时候联结各车围成营地，不必再另行挖沟堑，筑营垒，非常方便坚固。 
其布阵之法，则每军二千五百人，以五分之一，凡五百人为将佐卫兵及辎重之属，余二千人为车八十乘，欲布方阵，则面各用车二十乘，车相联，而步卒弥缝于其间，前者其车向敌，后者其车倒行，左右者其车顺行，贼攻左右而掩后，则随所攻而向之，前后左右，其变可以无穷，而将佐卫兵及辎重之属，皆处其中，方圆曲直，随地之便，行则鳞次以为阵。止则钩联以为营，不必开沟堑，筑营垒，最为简便而完固。 
The deployment method is that each army has 2,500 soldiers, of which one-fifth are generals, guards, and logistics support soldiers, and the remaining 2,000 soldiers are divided into 80 chariots, arranged in a square formation, with 20 chariots on each side, the chariots are connected, and the soldiers march in the gap between the chariots, the chariots in the front row can advance forward, and the chariots in the back row can advance backward, and the left and right can also be pushed out, the enemy attacks the left and right, and then attacks him from behind, and defends according to the direction of the enemy’s attack, there can be a variety of changes, and the generals, guards and logistics soldiers are all in the square formation, which can also be transformed into a circular arc according to the terrain, and the infantry in the formation can be re-arranged when marching, and the vehicles can be connected to form a camp when resting, without the need to dig trenches or build fortresses, which is very convenient and strong.
