《三国志·魏书·任苏杜郑仓传》
敌军多次前来劫掠，还断绝运输粮食的道路，任峻就分一千辆粮车为一部，形成十路方正的队伍，又形成方阵守卫粮食，敌军不敢靠近。
贼数寇钞绝粮道，乃使千乘为一部，十道方行，为复陈以营卫之，贼不敢近。
The enemy came to loot several times and cut off the transportation route for the food, so Ren Jun divided a thousand food carts into one part, formed ten rectangular teams, and formed square arrays to guard the food, and the enemy did not dare to approach.
