I revised my paper explaining Mils/MOA, S-MOA and the Range
Equations by taking out the math parts and simplifying it for those not
interested in all the math. This is a reference manual. I hope you enjoy it, learn from it and pass it along.
Thank you.

Actually, artillery and tanks,especially,use mils differently. What they are referring to is a gunner's mil, not a miliradian. A gunner's mil is 1/6400 part of a circle. So there are 17.778 mils per degree. There are 17.453 miliradians per degree. Russian and some other armies use different # of mils per degree.

As an Appleseed instructor we cover the basics of MOA and finding an easier way to explain this to folks who've never heard of MOA would be great!

There is no such thing as a gunners mil, its a mil or a NATO Mil.  The Russian system is called the DC system and is 1/6000 of a circle.  

The Mil has been used by European militaries since the late 1800s and entered US military service in 1904 when we bought French Pantels, it also used on various other sights, compasses and on tripods.  


The shooting community has misappropriated the term Mil to refer to milaradians, a term that had been used for over a hundred years and on thousands of weapons sights prior to the guys at WTBN using milradians instead of mils like the rest of the military.

I am certainly NO EXPERT.........was it wrong for me to always assume that 1 mil is 1,000th of my distance to the target?

How did they get 1/6,000?

There are always double the PIE amounts of radius around a circle........or 6.28 times the radius and 3.14 times the diameter across the circle.

Hey thanks, I just retrived the new and older version with my scribed app.  I read through the newer one 27 pages, it looks and reads well.  Good explanation of the MOA.  

Solid work.

They artificially divid a circle into however many "mils" they want, whether it's 1/6000, 1/6400, 1/6300 etc. They then use trigonometry to figure out the equations for distance measurements. In 2007 when I first wrote my papers on the subject, I actually did it on both the "true mil" and what some called the "military mil" (1/6400). When I called the scope manufactures up to find out which one they used, (many didn't really know at first and had to research it) they all said they used the real or "true mil" in their scopes. Therefore, I rewrote it on just the "true" mil version. I might have an old copy of it. I'll see if I can't fetch out a picture of it. EDITED: Found it.

Thanks........I am assuming the Russians just made 6 equal triangles out of a circle and 1,000 mils per each triangle..........which gave them 1/6000 per mil.  Just arbitrary I assume.

Also........if you have a guy you know is, or assume is, 2 meters tall and he covers 2 mils on your target you would know he was 1,000 meters distant.............right?

ETA:  Thanks for the update!!

I like the non Russian one (true mil) better.........easier math wise IMHO.

Your update shows the height of the target in yards in our system is what is used rather than in meters...........I always assumed meters.........thanks again!!

Yes, using the 4th equation down on page-25 of the short version, you would get 1000 meters distance to him. P.S.  I hope I'm not that guy that I just helped you range.

No, no.........you are just affirming things I assumed...........nice to know I was right on something for a change.

Remember, mils are independent of the units used. They express a ratio of the arc to the radius in whatever units you prefer. See pages 5-7 of the short version.




Edit:



RDak, Roger. Sorry I misunderstood.

They worked backwards. They just divided up the circle into 6400 small sections they called "mils", then figured out via trigonometry what each of those "mils" equaled and came up with an equation. That's how I did it way back in '08 (see my pic posted a few above of that original paper).
