The Coriolis Effect

A rotating Round Earth model predicts that bodies which move through the air will be appear to be deflected Eastwards or Westwards in their path of movement due to the rotation of the earth. This effect has been termed the "Coriolis Effect."

The Coriolis Effect, however, is a fictitious effect that is not, and has never been, demonstrated with experimental evidence. Its proponents are unable to show that this effect has ever been detected or that it is truly necessary to account for in various operations. The evidence for this effect appears to be based entirely on 'common knowledge', on how things 'should be', and by authors who make 'predictions'; but all articles and documents presented in favor of the "Coriolis Effect" are without reference to, or demonstration of, the critical and necessary experimental evidence to directly prove the matter.

=Artillery=

It has been alleged that the Coriolis Effect plays a part in the ballistic trajectory of artillery, and that artillerymen must account for it for accuracy. We are presented with military instructions and range tables for accounting for the Coriolis Effect, and so, it is speculated, the Coriolis Effect must be a real effect.

U.S. Army Artillery Coriolis Table Example
We are directed to the table from following document:

The Production of Firing Tables for Cannon Artillery (1967) http://www.dtic.mil/dtic/tr/fulltext/u2/826735.pdf

Pg 103, Table H, Corrections to Range, in Meters, to Compensate for the Rotation of Earth:



When challenged on the accuracy of this table, the Coriolis Effect proponent proclaims that if it were incorrect then artillerymen would be routinely inaccurate and miss their targets, and how could that be the case?

Artillery Ballistics Not Accurate
From the the above paper, from the introduction, we read that military artillery, which is purported to require adjustments for the "Coriolis Effect," is indeed, routinely inaccurate. The first round generally misses its target. Only after missing a number of times, and then adjusting the alignment of the cannon to compensate, does the artillery hit its target.

From the above 1967 artillery paper we read:

In another artillery paper from 1973, we read a similar quote:

http://www.dtic.mil/dtic/tr/fulltext/u2/909704.pdf

In 2016 a claimed expert named Guy Schuchman says that, despite GPS and modern improvements, the same problems exist today:

A 2017 paper by Australia's Armament Research Service admits the same:

=Sharp Shooting=

It has been alleged that the Coriolis Effect also plays a part in accurate sharp shooting over long distances. However, we find several online references where claimed sniper veterans have stated that they have never taken the Coriolis Effect into account when shooting. We are pointed to the U.S. Marine Corps Sniping Manual, which does not mention the Coriolis Effect anywhere in the text at all.

U.S. Marine Corps Sniping Manual
U.S. Marine Corps Sniping Manual 1981 Version Full Text 2016 Version Full Text

The sniper must know the general principles of: perspective, vanishing point, perspective drawing, delineation, and geographical areas of intelligence operations. However, the words "Coriolis" or "Coriolis Effect," do not appear anywhere in the U.S. Marine Corps Sniping Manual.

The curious reader might ask why the U.S. Marine Corps does not teach this allegedly important effect to its snipers.

Misleading References
The internet is rife with references that the Coriolis Effect is actively used, but this is an assumption without demonstration.

This quote actually says "these are the factors that will affect the bullet," rather than "these are the factors that the sniper accounted for." One is a commentary by the author and the other is a depiction of process. The reader should be able to see that there is a difference.
