远程狙击密位点知识

elevation knob 仰角调整旋钮windage knob 风偏调整旋钮modifled mil dot reticle 密位点瞄put the mouse cursor over the elevation and windage knobs to see the tops把鼠标的光标移动到仰角调整旋钮和风偏调整旋钮顶部。the mil dot reticle is the standard in tactical rifle scopes the mil scale can be used just like a ruler to measure the height of a target if the actual size of the target is known then the range can be calculated using a simple formula这个十字线密位点是标准的战术步枪使用光瞄，这个密位刻度如同一把尺子来测量目标的高度。如果目标的实际尺寸已知，则需要简单的一个计算公式来求出目标距离。in the simulations you will be using a modified mil dot reticle. one difference from a standard mil dot reticle is that a fifth dot takes the place of the broad posts at the edge of the field of view this reticle is a wire with 1/4mil dots spaced 1 milliradian apart there are 5 mils between the center cross hairs and the center of the outside dot 为在这个模拟软件中，你将会使用一个修改过的密位点瞄，标准密位点和修改密位点的差别是第5个密位这个边缘粗线处地方。1密位点长度为1/4密大小，2个密位点之间的距离为1密，瞄中心至瞄镜外端上下左右各有5个密，用细线连接各个点。in this reticle the dots are actually more oval than round the length of the dot is 0.25 mil在这个十字瞄内，点其实是椭圆形的，一个点的长度就是0.25密.a milliradian is an angular unit of measure 1 millradian equals one yard at 1000 yard and 1 meter at 1000 meters if you know the height of the target multiply it by 1000 and divide by the mil dot size of the target to get the range密是角度计量单位，1个密代表的是1码在1000码的长度，或者1米在1000米的长度，如果你知道了靶子的高度码用它来乘以1000并除以测量得到的密的读数就可以算出靶子的高度来。靶子高度码*1000- = 距离码靶子所占的密位读数for precision work mill readings need to be accurate to the tenth of a mil in the simulations you will meed to go through the calculations to determine the range ,in the field you can use commercially available data books or other range calculating devices such as a mil dot master ,but it is a good idea to have a solid background in range estimation using the equation如果需要读数精确的话，可以把一个密划为10份,在这个模拟软件中，你可以通过计算或者其他一些使用工具来测算密位，在这个模拟环境中使用公式来计算距离。now try mil dot ranging现在我们尝试密位测距计算、click on the scope image and hold with the mouse button to drag the scope around this 30 inch*18 inch target is at 500 yards ,you should get a mil dot reading of a little under 1.7启动这个瞄，移动你的鼠标放在这个30英寸*18英寸这个靶子上面，这个靶子在500码，你测量得到数据为靶子高度为1.7密实际1.666。这个30英寸*18英寸的靶子在720码的距离。那么它所占的密位读数是多少？注：submit是提交的意思。the mil dot reading for this target appears to be about 1.3 since we know the target is 30 high we can enter this information into the formula这个密位读数大约在1.3，我们知道这个是30英寸高的靶子，所以通过公式计算目标高数据为.833码。the actual range is 650 yards so we came up a little short however ,at this range we are only 2 inches low ,close enough.这个实际的距离数据在650码，我们射击的弹着要低一些，但是我们射击的位置只低于目标中心2英寸，射击的效果很好。determine the range of this 30 high target ,feel free to use the calculator ,hint:this is an easy one确定你瞄中靶子的高度为30英寸，不要客气地使用计算器。注意：这个是一个简单的计算。the horizontal milldots can be used for holdoff in wind conditions or as leads for moving targets the vertical mil dots can be used for elevation hold-over or under when there is not time to make an adjustment to the elevation, the may come in handy if the first shot misses the target and a correction meeds to be made before the target gains cover.这个水平状态的密位瞄，可以使用于风偏条件以及运动目标的射击，可以使用下面的垂直密位点来修正弹道下坠落差，校正射效，如果有目标脱靶而来不及调整旋钮，就可以使用垂直密位点快速射击。1 mil is equal to 3.438 moa1个密等于3.438MOA角分in order to use the mil dots for hold-off you need to convert the mil dot distance to moa.this is where some confusion comes in ,the reticle used in these exanples uses the usmc standard of 1 mil equals exactly 3.438moa the standard used by the army is 3.6 many people use 3.5 since it is in-between the two.你需要学会懂得密位和MOA之间换算公式，这里有一点混乱之处在于海军陆战队是把一个密化为3.438MOA，而美国陆军却是3.6moa，而很多人喜欢用2者之间的数据3.5MOA。400 yard hold under point400码目标的瞄准点位置600 yard zero600码的归零位置。suppose your rifle is zeroed for 100 yards and you have set your elevation for a target at 600 yards which you have just hit.suddenly a target pops up at 400 yards .you do not have time to re-adjust the elevation setting to engage the new target ,since there is a 7.75moa difference in elevation between 600 and 400 yard you need to hold under 2.25mils to hit the closer target.现在假设一下你的步枪归零在100码距离，你准备操射击600码距离的目标射击已经设置好600码距离的装载数据，但是一下又在400码弹出了一个新的目标，你没有时间去调整手轮旋钮再去修正射击这个新的目标，而400码和600码之间的MOA差值是7.75MOA，利用弹道射表去观看数据两个之间的差值除以3.438等于2.25密，来做为修正的密位点瞄准位置。译者注：600码的归零打400码的目标，需要降低瞄准点用十字线上2.25密点对准目标中心射击。750 yard zero 750码归零new target at 850 yards新的目标在850码you have hit the center of 30*18target at 750 yards a new target
