Which type of fire is used for moving targets that require adjustments?

The correct choice for dealing with moving targets that require adjustments is free gun fire. This method allows the operator to move their weapon freely to track and engage targets as they move, enabling real-time adjustments in aim. Free gun fire is particularly effective in scenarios where targets are not stationary and can change position quickly, as it permits a more fluid engagement than other types of fire.

In contrast, searching fire typically refers to a technique used for area suppression where the gunner moves their line of fire in a sweeping motion to locate and engage targets, but it does not allow for precise tracking of specific moving targets. Fixed fire involves setting the gun in a designated position to fire at a target that is not expected to move significantly. Direct fire is generally aimed at a known enemy position but does not inherently account for the need to adjust for moving targets. Thus, free gun fire is the most suitable choice for situations involving moving targets that necessitate adjustments.
