What is one effect of the ammo type used when firing a machine gun?

The choice that indicates the effect of ammo type on the path of fire is accurate because different types of ammunition can significantly influence the projectile's trajectory. Factors such as bullet weight, shape, and type (e.g., armor-piercing, hollow-point, or tracer) can lead to varying levels of drop and wind resistance. For example, a lighter bullet might be affected more by wind than a heavier round, causing it to deviate from the intended path. Additionally, certain ammunitions are designed for specific purposes, which can affect how they interact with the environment upon firing. This is essential knowledge for machine gun employment, as understanding these nuances allows operators to adjust their aiming and firing techniques accordingly based on the ammunition being used.
