What type of fire results when the center of the fire does not rise above one meter off the ground?

Grazing fire is characterized by projectiles whose center of impact remains at or below one meter off the ground. This type of fire ensures that bullets travel in a relatively flat trajectory, allowing for effective suppression of targets that are either standing or crouching behind cover within that height range.

The primary advantage of grazing fire is the reduced risk of the rounds being deflected or interrupted by terrain features, making it highly effective for engaging personnel within that height limit. It is particularly useful in situations where enemy forces are likely to be moving or taking cover at low positions.

In contrast, the other types of fire mentioned in the question have different characteristics and implications for tactical situations: danger space refers to the area where a projectile could hit a target, enfilade fire involves firing along the length of an enemy formation to maximize damage, and flanking fire is directed at the side of a target, which can create confusion and disarrays among enemy forces. Understanding grazin fire and its applications is essential for effective machine gun employment on the battlefield.
