Which of the following is a method used in deliberate range determination?

The correct answer, which focuses on a method used in deliberate range determination, is based on the principles of accurately estimating distances using existing reference points. The map reference method involves analyzing a map to find precise distances between points, allowing for effective planning and engagement of targets.

Using map references is crucial because it provides an accurate way to determine range based on scaled distances marked on the map. This method also helps integrate terrain analysis into range estimation, which is essential for mission planning and execution.

While other methods such as the football field method, range recognition, and the flash to bang method have their utility in various contexts, they do not specifically constitute deliberate range determination as effectively as map reference does. The football field method relies on visual estimation based on familiar distances, range recognition is based on the ability to judge distance through experience, and the flash to bang method assesses the time interval between seeing a flash (like an explosion) and hearing the sound, which is more related to timing rather than precise range determination.
