Which type of firing does NOT require constant adjustment of the weapon?

Fixed Fire is characterized by the placement of the weapon in a designated position where it remains aimed at a specific target without the need for constant adjustments during operation. This type of firing is typically utilized when the target location is known and remains stable, allowing the operator to maintain focus and deliver sustained fire without needing to reposition the weapon.

In contrast, the other types of firing methods require adjustments either due to the need to track moving targets or due to shifts in the tactical situation. In Swinging Traverse, the gunner must pivot the weapon to follow targets moving along a horizontal plane. Searching Fire involves scanning an area for targets, requiring the weapon to be adjusted both vertically and horizontally. Traversing Fire is similar to Swinging Traverse but may also incorporate elevation adjustments. Each of these methods necessitates continual modification of the weapon's aim, which is not the case with Fixed Fire.
