I heard that the reason is 1km away it makes a difference of 1m, so easy to figure out how far enemy troops are from each other.

Thus, when observing things of known size through some optic with a reticle graduated in mils, you can easily determine the range to them. Which then gives you e.g. the amount of holdover necessary to hit the target with a gun (which can itself be expressed as number of mils on the reticle to aim above).
- quickthrower2 4y agoAh of course it is the other way around like you say. You know the size of things, you need to figure out the distance.
