What is the purpose of 'Creeping fire'?

The purpose of 'Creeping fire' is to gradually adjust fire to reach the target, making it a methodical approach to ensure accuracy in artillery or indirect fire operations. This technique allows forces to effectively engage a target by systematically moving the point of impact closer to the intended target area.

The method is particularly useful for suppressing enemy positions while minimizing the risk of overshooting or missing the target, which could harm friendly forces or civilians nearby. By controlling the fire in increments, the gunners can fine-tune their adjustments based on initial impacts, allowing for a more precise strike while maintaining continuous pressure on the enemy.

Other options, such as firing at a moving target or a sudden volley of rounds, do not encapsulate the deliberate and controlled nature of 'Creeping fire'. Heavy suppression before an attack, while related to preparatory bombardments, also does not convey the incremental adjustment aspect central to 'Creeping fire'.
