In which situation is grazing fire considered effective?

Grazing fire is most effective when firing at level or uniformly sloping terrain because this type of fire allows the bullets to travel close to the ground and impact targets with minimal elevation. In this scenario, the trajectory of the bullets remains low, which means they are less likely to rise above the target and instead maintain maximum effectiveness against enemy personnel or equipment. This method of fire minimizes the risk of bullets going over the intended target while maximizing the coverage of the area being targeted.

In contrast, when the center of the cone of fire rises above two meters, the effectiveness of grazing fire is diminished because the rounds may no longer be impacting at a low angle, thus not utilizing the benefits of grazing fire. When the target is directly in front of the firing position, although it can be effective, the primary advantage of utilizing grazing fire is reduced since there may be no slope to optimize the bullet trajectory at low levels. The traversing fire method pertains more to adjusting fire along a horizontal plane and does not specifically relate to the concept of grazing fire's effectiveness based on terrain. Thus, the best context for effective grazing fire is when the firing is directed at level or uniformly sloping terrain.
