| − | 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."

| − | Coriolis Effect, however, is a fictitious effect that 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 for various operations. The evidence for this effect appears to be completely based on 'common knowledge', on how things 'should be', and on documents which make 'predictions', all without reference or demonstration of the experimental evidence which proves the matter.

| − | It has been alleged that the Coriolis Effect plays a large part in the trajectory of artillery munitions. We are presented with military instructions and range tables for accounting for the Coriolis Effect, and so therefore it must be a real effect.

| − | It has been alleged that the Coriolis Effect plays a large 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.

| − | 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 internet is rife with references that the Coriolis Effect is actively used, but this is an assumption without demonstration.

| − | {{cite|To understand the complexity of the shot, it’s best to start with a sniper maxim: sniping is weaponized math. Although a .50 caliber sniper rifle bullet can fly as far as five miles, a host of factors including gravity, wind speed and direction, altitude, barometric pressure, humidity and even the ''Coriolis Effect'' act upon the bullet as it travels. Even worse, these effects increase the farther the bullet travels. A successful sniper team operating at extreme distances must do its best to predict exactly how these factors will affect the bullet and calculate how to get the bullet back onto target.}}

| − | 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. Reader should be able to see that there is a difference.

| − | As for water currents on a large scale; they're simply gradually put into motion by the winds. Water currents in the Northern Hemisphere will tend to rotate in one direction while currents in the Southern Hemisphere will tend to turn in another direction.
