大家在看关于狙击手的电影时,往往看到狙击手在别人看不到的远距离将敌人一枪毙命。确实,无论是造型帅气的狙击枪,还是冷静射杀敌人的狙击手,都令人兴奋。那么大家想过一件事情没有?为什么狙击枪和瞄准镜不在一条直线上,却能命中目标呢? 首先,大家都知道:子弹出膛之后,不是按照直线运动的,准确的说,应该是一条抛物线。而狙击枪的瞄准镜,也不会是水平安装在枪上面,一般前端会低出一些角度,以便于准心能够和抛物线产生焦点。这个焦点就是子弹命中的点,从理论上来说,只要瞄准镜的轴线和弹道在目标位置相交,就能命中。 像游戏里,不少枪的开镜和枪口是无论是敌人距离有多远,始终在一条准心上,这一点是不对的。因为真实情况是,瞄准镜上面一般有两个信息拧镜筒的旋钮按钮,以便调整具体的精确准度。 这其中,有个*为重要的因素,那就是距离归零。距离归零的意思,就是在狙击步枪的瞄准镜上面调整与目标的准确距离。在准确的指定距离刻度上,才能保证瞄准镜准心与子弹的焦点基本相同。比如在距离四百米的地方有需要射击的目标,这时候你瞄准镜上面的归零还在一百米,这就一定是打不中的。 上图:Onick微光夜视瞄准镜 当然,影响狙击枪精确打击的,还有其他因素,比如风向、目标移动方向、枪口初速、湿度等。而瞄准镜也只是起到一个放大的作用。想要准确的射击目标,也要狙击手自己算好提前量,一般为了应付这种情况,还会给狙击手配备一名观察手。但如果一名狙击手,连自己枪上面的瞄准镜都不能玩转,哪又何谈什么命中目标呢? Of course, there are other factors that affect the precision attack of sniper rifles, such as wind direction, moving direction of target, muzzle velocity and humidity. The sight only plays a role of enlargement. If you want to shoot the target accurately, you also need to sniper yourself ahead of time. Generally, in order to cope with this situation, snipers will be equipped with an observer. But if a sniper doesn't even play the sights on his gun, what's the goal?
