Binocular reticles. (1 Viewer)

[Binastro]

There are about 6,283 mils or milliradians in a circle.

1000x 2Pi.

However, Nato use 6400 'mils'.
Warsaw pact 6,000.
Sweden 6,300.

This is to allow easy division.

And the Swiss apparently use 6,400 but measured from north, true or magnetic I don't know.

So, are the reticles on binoculars true mils, 6,400 for Nato binoculars?
6,000 for Warsaw pact binoculars and 6,300 for Swedish binoculars?

How does this fit in with other equipment, say modern digital that may use true mils?

What happens if a country joins another organisation?

Questions, questions?

Regards,
B.

Hello Binastro,

The reticle is used by militaries to estimate distance for small arms, like rifles, and for mortars. Range has to be set on a rifle's site, probably in increments of 100 metres, to accommodate the fact that a round will not trace a straight line, but would drop as the it travels. The difference between milliards and mils won't be of much consequence in those uses. A sniper might need something more accurate.The artillery on a tank would be more demanding of accuracy, so I would guess that tanks are equipped with optical rangefinders, laser rangefinders and perhaps radar.

When the former Warsaw pact countries entered Nato, their arms and their optics had to changed to match NATO standards.

Stay safe,
Arthur
