As an observer, which of the five requirements for achieving accurate first-round fire for effect are you solely responsible for?

As an observer, your primary responsibility for achieving accurate first-round fire for effect includes accurately determining the target location and size. This is crucial because precise targeting directly influences the artillery's ability to engage effectively. Understanding the exact coordinates (latitude and longitude) and dimensions of the target allows you to convey accurate information to the firing unit.

Target location must be as precise as possible to ensure that rounds land on the intended target area. The size of the target also plays a critical role in calculating the necessary adjustments for the artillery, as larger targets may allow for more leeway in accuracy, while smaller ones demand pinpoint precision. Accurate reporting of this vital information eliminates ambiguities and misrepresentations, which are essential for successful artillery operations.
