Which type of fire occurs when the weapon is fired without aiming down the sights?

The correct answer identifies that free-gun fire occurs when a weapon is fired without aligning the sights. This method is often employed in situations where the shooter needs to engage quickly, such as in close combat or when the target is moving rapidly, making it difficult to take the time to aim properly. Free-gun fire allows the operator to maintain a high rate of fire and react swiftly, though it sacrifices precision for speed.

Other fire types serve different tactical purposes or employ specific aiming techniques. Enfilade fire involves firing along the longest axis of a target, maximizing the weapon's impact. Fixed fire refers to a position where the weapon is aimed and held steady on a particular target or location, emphasizing aimed shots. Grazing fire is characterized by a projectile's flight path being low enough that it strikes the target while remaining close to the ground, similar to how a grazing animal feeds, but it still requires some aiming. Understanding these definitions helps clarify the context and importance of each firing technique in infantry operations.
