ATACR F1 - FC-DM Reticle
So I've been experimenting with using the ATACR F1 sight, and I noticed that it's mil-dot ranging is off by two. Specific example: go into the arsenal and compare with vanillarma Nightforce NXS (LRPS).

If you assume enemy soldier height is 1800, then point the weapon at the soldier at 500 meters, then the soldier will measure 4 mildots with the vanille NXS/LRPS. The formula then goes like such:

1.8 x 1000 / 4 = 450. Give or take 50 meters. Which, falls in line with the target distance being 500 meters.

Now, if you do the same experiment with the ATACR F1, you will notice the soldier measures 2 mildots (using the highest magnification available). Which, if we use the same calculation ... 1.8 x 1000 / 2 = 900. Give or take 50 meters. Which ... Gives us an approximate distance between 850 and 950. Twice that of what the real distance it.

Luckily, the reticle is wrong by an exact number (times two), so it's not that hard to just do 1.8 x 1000 / 2 / 2 = 450, if you know that the reticle is wrong. But if you don't, you're basically over-ranging, twice. Incidentally, having to do one more division reduces accuracy, too.

Is this something that is only on my end, or can I report this for bugfixing?
