When is grid north used in relation to a military map?

Grid north is an essential reference point used in military mapping and navigation that corresponds to the grid lines on a map. When plotting coordinates, it is important to use grid north to ensure accuracy in determining precise locations on the map. The grid north aligns with the vertical lines of the grid system, providing a stable reference for locating specific points.

Understanding the distinction between grid north and other directional references, such as magnetic north, is crucial for successful navigation and operational planning. In this context, grid north helps the user translate coordinates from the grid system into real-world locations, making it the appropriate choice for this question.
