在一些影视剧中,大家经常看到这样的镜头,一个步枪瞄准镜的特写,然后镜头拉近,瞄准镜的十字对准一个悍匪的脑袋,随后一声枪响,悍匪毙命…,其实这是影视剧为了强化影视效果对观众的一种误导,因为通常我们的瞄准线是一条直线,而真正的子弹飞行路线却是一条弧线,这条不确定的神奇线路受到地球引力、温度、高度、风速、风向、射程等等客观因素的影响,所以射击时真正的弹着点和瞄准点是存在一定的偏差的,人们经过了长时间的实践和摸索,终于发现在已知上述条件的前提下,弹道或者说是弹着点是可以准确计算和预测的,然而,密林中潜伏的狙击手毕竟不同于都市中行走的商务白领,可以在手提包里带上台笔记本电脑,最初的狙击手们主要靠丰富的实战经验来粗略计算弹着点,以修正瞄准基线,如今这种做法和信息时代似乎有些格格不入,美国5.11H.R.T.手表为前线的狙击手们带来了福音,因为除了具备所有的计时功能外,这种能够达到100米防水深度的手表还搭载了一部小型弹道计算机,出色的解决了远距离射击时的弹道计算问题,在实际的使用过程中,手表需要做初始化和参数设定等一系列操作;下面就以图解的方式,为大家简要的介绍一下5.11H.R.T.弹道计算手表的功能和使用方法。
In some TV series, we often see such a shot, a close-up of a rifle sight, then the lens is closer and the cross of the sight is aligned with the head of a ruthless man, followed by a gunshot and a ruthless death. In fact, Is a misleading view of the audience for the film and television drama to enhance the film and television effect, because usually our line of sight is a straight line, but the real bullet flight route is an arc, this uncertain magic line is subject to the gravitation, temperature and altitude , Wind speed, wind direction, range and so on objective factors, so the firing point of the real bomb and aiming point there is a certain deviation, people after a long period of practice and exploration, finally found under the premise of the above conditions, However, the hidden snipers in the Jungle, after all, are different from the business white-collar walking in the city. They can bring laptops in their handbags. The initial snipers mainly rely on a wealth of actual combat Experience to roughly calculate the bombing point to correct the aiming at the baseline, now this approach and the information age seems to be somewhat out of date, the United States 5.11HRT watch Bringing the gospel to the front-line snipers, because in addition to having all the timing features, this watch can reach 100 meters waterproof depth is also equipped with a small ballistic computer, excellent solution to the ballistic calculation of long-range shooting Problems in the actual use of the process, the watch needs to be initialized and parameter settings and a series of operations; the following on a graphical way, for everyone a brief introduction of 5.11HRT ballistic function and use of watches.
