Under which condition is grazing fire typically achieved?

Grazing fire is achieved when the weapon is fired in a manner that keeps the bullet trajectories close to the ground, effectively allowing the bullets to strike enemy targets while minimizing the risk of ricochet or hitting unintended targets above the line of fire. This firing technique is most effectively employed over level or uniformly sloping terrain because it ensures that the bullets remain within a few inches of the ground throughout their flight, keeping them oriented at a low angle.

When the terrain is level or uniformly sloping, the chances of maintaining a consistent grazing fire pattern are significantly enhanced. This allows for effective suppression of enemy personnel and positions while maximizing safety for one's own troops and minimizing collateral damage. Other terrain conditions, such as high terrain, rivers, or valleys, could complicate the angle of fire and trajectory, making it more difficult to achieve grazing fire effectively.
