What is the purpose of a 2-point resection in navigation?

The purpose of a 2-point resection in navigation is to find your position using two known landmarks. This method involves identifying two fixed reference points or landmarks that are visible from your current location. By measuring the angles or distances to these two points, you can triangulate your position on a map. This technique is particularly useful in situations where GPS might be unavailable or unreliable, allowing infantry personnel to accurately determine their location based on recognizable features in the terrain.

The other options, while related to navigation, do not accurately describe what a 2-point resection achieves. For example, determining the distance to a known location is a different navigational process that focuses more on distance measurement than on positional triangulation. Establishing a moving target relates more to tracking or engagement strategies in combat rather than finding one’s location. Lastly, calculating azimuths for combat engagements involves understanding directional angles rather than pinpointing one's own location using landmarks.
