I can't help learning a few artillery ranging method Jinzhou Teachers Training College In the first episode of the TV series "Bright Sword", there is such a heartening picture: the Eighth Route Army, the new regiment leader Li Yunlong ordered the gunner "columns" to use the mortar to blow up a few hundred meters away from the Japanese command headquarters, only to see "columns". "set up the gun, stretching his right arm, squinting his left eye, adjusting the angle of the muzzle, loading shells ... only two shells, the Japanese Sakata command headquarters, so that the enemy became a headless fly, so that the troops victoriously rushed out of the enemy's encirclement. So why did Pillar hit every shot? The key is that he measured the distance accurately. This article introduces you to several artillery commonly used ranging methods.　　First, jumping eye method jumping eye method is commonly used in our army simple distance measurement method. Pillar in the television series "bright sword" is used in the "jumping eye method". Its specific method is: straighten the arm forward, straighten the thumb, close the left eye, so that the right eye line of sight along the side of the thumb to the left side of the target, the head and hand to remain motionless, and then close the right eye, so that the left eye line of sight through the same side of the thumb, and remember to align the line of sight to the field at a certain point, and then visually measure the target to the left side of the width of the point, will be multiplied by the width of this 10, that is, for the standing person to the target of the distance. The principle of the jumping eye method is that the interval between the pupils of the two eyes is about one-tenth of the length of one's arm, and the measured width of the object in the field is multiplied by 10, which gives the distance from the standing point to the target. Not long ago passed away the volunteer army outstanding sniper Zhang Taofang best at this method. In the Shangganling sniper battle, Zhang Taofang used the Mosin-Nagan rifle is not equipped with a scope, distance measurement mainly rely on visual inspection, and three months killed 214 enemy performance, but also proved skillful use of the jumping eye method of measuring the accuracy of the distance.　 /url.asp?pages=12160901694675
