Which class of fire involves gun fire that is level with the ground?

The class of fire that involves gunfire being level with the ground is known as grazing fire. This type of fire is characterized by the trajectory of the rounds remaining close to the ground, usually within a few feet, which allows it to engage targets without obscuring terrain. Grazing fire is particularly effective for defense as it minimizes the risk of rounds being deflected or becoming ineffective due to elevation changes in the landscape.

In contrast, plunging fire has a steep angle of descent, searching fire typically involves sweeping movements to cover an area, and traversing fire is about moving the aim from side to side to target multiple threats. Each of these types of fire has its distinct characteristics and applications, but grazing fire specifically emphasizes alignment with the ground, contributing significantly to its effectiveness in combat scenarios.
