Which class of machine gun fire may require the use of multiple shooters for effective execution?

The correct choice highlights the concept of traversing and searching fire, which is typically employed when engaging targets that may be dispersed across a wide area. This class of fire often necessitates multiple shooters to effectively cover a larger sector, ensuring that targets that may be moving or located at varying distances can be engaged without leaving gaps in coverage.

In traversing and searching fire, one gunner would typically adjust the fire's direction while another gunner can provide supporting fire or cover different angles, increasing the overall effectiveness of the machine gun team. This strategy is particularly valuable in combat scenarios where targets are not stationary or concentrated, and multiple shooters working in concert can maximize their firepower and operational flexibility.

Other types of machine gun fire, such as fixed fire, flanking fire, and free-gun fire, do not usually require the coordination of multiple shooters to the same extent. For example, fixed fire involves a set aim point, and a single shooter is sufficient to engage the target effectively. Flanking fire mainly emphasizes the angle of attack rather than the number of shooters, while free-gun fire allows a single operator to fire from various positions without needing additional support. Thus, the unique requirements of traversing and searching fire make it dependent on multiple shooters for
