Which class of fire involves firing from a fixed position without moving the gun?

The class of fire that involves firing from a fixed position without moving the gun is referred to as Fixed Fire. This technique is significant because it allows the weapon to maintain a consistent line of sight on a target, enhancing accuracy and reducing the time needed to engage multiple threats. When employing Fixed Fire, the operator can focus entirely on aiming and firing rather than managing the mechanics of moving the weapon, which is essential in situations where rapid and precise fire is necessary.

In contrast, other classes of fire entail varying degrees of gun movement. For instance, Traversing Fire involves shifting the orientation of the gun while firing, which can adjust the line of fire but may complicate aiming and target acquisition. Swinging Traverse similarly requires the gun to pivot, adding movement to the firing process. Free Gun refers to firing while the gun is not stabilized or locked into a particular position, which usually demands more skill and increases the likelihood of errant shots due to the lack of stability. Thus, Fixed Fire is distinctive and crucial in machine gunnery for its emphasis on stability and accuracy in engagement.
