What type of fire is characterized by a projectile's capability to remain close to the ground?

The type of fire characterized by a projectile's capability to remain close to the ground is grazing fire. This form of fire occurs when the trajectory of the projectile flies at a low angle, ensuring that it stays close to the surface. Grazing fire is effective in engaging targets that are at or near the same height as the shooter, minimizing the risk of fire falling high and missing the target altogether.

Grazing fire is particularly useful in flat or low-lying terrain, where the low angle of the fire reduces the likelihood of missing an enemy target behind cover. The effectiveness of this type of fire contributes to its selection in tactical situations where precise targeting is crucial, allowing soldiers to engage effectively while maintaining a reduced risk of collateral damage.

In contrast, plunging fire involves projectiles that land from above at a steep angle, which is of less tactical utility in flat terrains. Traverse and search refer to different firing techniques and maneuvers used to engage targets but do not specifically pertain to the trajectory and ground proximity of projectiles like grazing fire does.
