What classification of machine gun fire is defined by the angle in relation to the ground?

The classification of machine gun fire defined by the angle in relation to the ground is best represented by high and low angle fire. In this context, high angle fire refers to shooting at a steep angle upward, while low angle fire is characterized by a flatter trajectory that typically runs parallel to the ground. Understanding these terms is crucial for effective targeting and engagement in varying combat scenarios.

High angle fire is beneficial for targeting enemies that are concealed or positioned at elevations, while low angle fire is more suitable for hitting targets that are at or below the gun's position. This classification aids gunner tactics and the overall effectiveness of machine gun fire in combat situations.

Conversely, classifications like plunging and grazing fire focus more on the relationship of the projectiles to the ground rather than strictly the angles of fire, while direct and indirect fire describes engagement methods based on the target's visibility from the firing position rather than the angles involved. Understanding these distinctions helps in employing machine guns effectively on the battlefield.
