Introduction
This guide is meant to show how to judge and correct for the distance to a target. I created these tables
under controlled conditions such as ideal weather, flat terrain, prone firing position, controlled
breathing, known target distances, and no fewer than five test shots per range. The following tables are
my best guess of target size and average point of impact. Some may not seem absolutely correct in ideal
conditions like the MK12 or DMR. These are estimates of the average point of impact for each given
range, not the point you will always hit. To create the mil-dot ranging scales, I used the formula:
2,000 times distance is equal to target size in mils
This is a variation of the Mil-dot ranging formula with an estimated human target 2 meters tall and 50
centimeters wide at the shoulders. Though this would indicate every character in the game is over 6’4”,
please keep in mind that this is a game. Target sizes, ranges, and even optics in ARMA 2 should not be
considered accurate to their real-life counterparts. However, this guide will assume that all optics are
reasonably correct, targets are 2 meters tall and 50 centimeters wide at the shoulders, and that basic
mil-dot ranging principles can be applied to ARMA 2.
Two things should be noted about the ballistics simulation in ARMA 2. First off, there is no wind drift.
Second, there appears to be no discernable need to adjust for elevation.

Principles of Mil-dot ranging

If you want an in-depth look at mil dots and how they actually work in real life, please refer to one of the
following websites:
http://www.boomershoot.org/general/TruthMilDots.htm

As most of you know, there are 360 degrees in a circle. A circle can also be divided into 2π (pie) radians.
One π is equal to roughly 3.14. Knowing this, there are approximately 6.28 radians in a circle.
Now, here is where mils come into play. Mil is short for milliradian. A milliradian is equal to 0.001
radians. So at 1,000 meters, a one meter tall target will appear one mil tall.

At 250 meters, a man will appear 8 mils tall; at 500 meters, that same man will appear 4 mils tall. This is
the absolute basic information needed on how to use mil-dots in-game to judge distances with the
tables provided in this guide. If you want to calculate the distance, you would take the height (size) of
the target in meters times 1,000. This would be divided by the size of the target in mils and would give
you the distance to the target in meters. Again, if you want to know more about milliradians and how to
use mil dots in real life, I recommend that you check out one of the above websites.

Using Russian PSO Scopes

Unlike the Mil-dot system, the Russian PSO-style scopes use a simpler method of determining range. On
the lower half is a scale showing the height of a human target at varying ranges. This SVD Dragunov
reticle has height markings for
200, 400, 600, 800, and 1000
meters. Target range can be
estimated by aligning the target so
that the feet touch the bottom line
while the head touches the curved
line. A distance can then be read
by judging where the head is on
the scale (the curved line). For
instance, if a target fit right below
the 6, he would be roughly 600
meters away. If the target was
between the 2 and 4, he would be
roughly 300 meters away. Once range has been established, you can use the chevrons at or below the
center-line to aim. Each chevron corresponds to the zero point at a certain range. For our imaginary
target at 600 meters, we would aim between the 3rd and 4th small chevrons. For the target at 300
meters, we would aim at the top of the 2nd small chevron. The following picture illustrates how you
would range a target. In this instance, the target is at 300 meters. This method of ranging might not be
as accurate as the mil-dot
approach, but range can
be determined a lot
quicker without the need
of conferring with a range
chart or calculating the
math yourself.

M24/M40 Ranging and Correction

The M24 and M40 in my testing appear to have the same ballistics. Because of this, I have only created
one chart for both weapons instead having two duplicate charts. Target height has been estimated at
two meters and target width has been estimated at twenty-five percent of target height giving us a
width of fifty centimeters. All shots and ranges were taken in the prone position with controlled
breathing. I have included a table with all my collected data and an abbreviated table with the target
height and correction. I have also color-coded the correction so as to not mistake a positive hold-over
for a negative-hold-over.
IMPORTANT NOTE: The space between the end of the last mil dot (the 4th from the center) and the thick
black line appears to be one mil, not point-nine mils. Also, the mil dots are assumed to be two-tenths of
a mil in diameter.
