What does "Splash over" indicate in the context of a Call for Fire mission?

In the context of a Call for Fire mission, "Splash over" refers specifically to the moment when artillery rounds begin to impact the target area. The term typically indicates that there are approximately 5 seconds until the rounds reach their target. This is a critical piece of information for the forward observer, as it provides a precise timing element for assessing the effectiveness of the fire mission and for coordinating actions with units in the area.

Understanding this terminology is essential for effective communication during a fire mission. The imminent impact of the rounds can influence tactical decisions among ground troops, such as moving out of cover or preparing to engage the target once the rounds have landed. Having this advance warning helps ensure that personnel in the vicinity are adequately prepared for the effects of the incoming artillery fire.
