Describe the procedure for adjusting the M240's sights.

Adjusting the M240's sights accurately is crucial for effective targeting, especially given the various environmental factors that can affect the trajectory of the bullet. The correct procedure involves using the windage and elevation knobs to make precise adjustments based on specific environmental conditions, such as wind speed, range to the target, and bullet drop.

Windage adjustments are made to account for any lateral displacement caused by wind, helping ensure that the bullet will hit the intended target horizontally. Elevation adjustments are necessary to account for how far away the target is, as well as any vertical displacement that results from environmental conditions. By taking both windage and elevation into account, operators can significantly improve their accuracy and effectiveness when engaging targets at varying distances and conditions.

Using fixed positions without considering range, only adjusting elevation knobs, or relying solely on confirmation from another operator does not allow for the needed flexibility and adaptation to the diverse shooting scenarios that might be encountered. Therefore, the method of adjusting both knobs based on conditions is essential for precision in operations involving the M240 machine gun.
