What is the essential purpose of "traversing and searching" fire?

The essential purpose of traversing and searching fire is to cover a wide area with fire. This technique involves moving the machine gun's firing pattern, either by pivoting the weapon from side to side or altering its elevation, to effectively engage multiple targets that may be dispersed across a broad front. By sweeping the fire across various sectors, the gunner can create a more comprehensive coverage, which is especially useful in scenarios where enemy forces are clustered in different positions or advancing in a wide formation.

This method maximizes the weapon's effectiveness by ensuring that rounds are delivered across a potential engagement area, thereby increasing the likelihood of hitting targets and providing suppressive fire that can impact the enemy's movement and morale. It is particularly valuable in situations where the enemy is maneuvering or where there is uncertainty about where the threat may arise, allowing for a flexible and adaptive response to evolving battlefield conditions.
