Which term describes the time delay before a scheduled fire mission?

The term that describes the time delay before a scheduled fire mission is "Time on target." This term specifically refers to the precise moment at which artillery rounds or other munitions are expected to arrive at the target after the fire mission has been initiated. Time on target is critical in fire support operations, especially when coordinating multiple units or ensuring that fire arrives simultaneously with other combat actions, such as troop maneuvers.

Understanding this concept is key for effectively planning and executing fire support in a tactical environment. The accuracy of timing can impact the overall effectiveness of the operation, making this terminology vital for those involved in coordinating artillery or air support.
