Because Earth is a rotating sphere, the Coriolis effect deflects the flight of a bullet to the right in the Northern Hemisphere & to the left in the South. The effect is tiny in most practical shootings and only needs to be considered in long-range shootings.
Many soldiers are not trained to account for the Coriolis effect, & flat-Earthers use it to “prove” it does not exist. In reality, most soldiers do not shoot long range. It is unnecessary to consider a few mm of deflection if the target is as large as an enemy soldier.

The “Field Artillery Manual Cannon Gunnery” (TC 3-09.81) is a manual from the US Army explaining the operation of field artillery. From the manual, we know the operators of field artillery are required to account for Earth’s rotation.
Flat-Earthers wrongly claim that an artillery operator never needs to account for Earth’s rotation. In reality, from this operational manual, we know their claim is incorrect.

Eötvös effect is the change in perceived gravitational acceleration when moving eastward vs. westward. An object will weigh slightly more when moving westward than when it is stationary or moving eastward.
The slight difference in weight due to the Eötvös effect can be measured in an experiment on a flight. The Eötvös effect is direct evidence that the Earth is a rotating sphere.

When a sniper shoots a long-range target, if he is in the northern hemisphere, the bullet is deflected to the right. Conversely, if he is in the southern hemisphere, the bullet is deflected to the left.
The phenomenon occurs because the Earth is spherical and rotating.
