一次,某新上任的军官到部队视察操练情况,发现有个士兵始终站在大炮的炮筒下,纹丝不动。经过询问,得知操练条例就是这样规定的。原来,操练条例因循的是马拉大炮时代的规则,当时站在炮筒下的士兵的任务是拉住马的缰绳,防止大炮发射后坐力产生距离偏差. Once, a newly appointed officer went to inspect the units and observed that there was a soldier standing under the barrel of the artillery gun, standing still motionless. After asking, that is the exercise of regulations is such a provision. It turned out that the ordinance is based on the rules of the era of the Mara Cannon. At that time, the task of the soldiers standing under the barrel was to pull the horse’s reins so as to prevent the cannon from generating recoil distances after launch.
