What are the three types of north on a military map?

The correct answer identifies the three primary types of north used on a military map: Grid, True, and Magnetic.

Grid north refers to the north that aligns with the vertical lines of the map's grid. These lines are typically based on the Universal Transverse Mercator (UTM) system used for precise, small area navigation within the military. Understanding grid north is essential for accurate map reading and navigation when working within the confines of a mapped area.

True north indicates the direction along the earth's surface to the geographic North Pole, which is a fixed point. This concept is crucial for broader navigation and understanding orientation beyond the immediate terrain depicted on a map. Knowing true north allows a soldier to align their orientation with geographical features and map projections accurately.

Magnetic north is defined by the direction a magnetic compass points, which is attracted toward the Earth's magnetic North Pole. Because magnetic north can vary slightly from true north and is influenced by local magnetic interference, it’s important for soldiers to be able to make adjustments and understand the discrepancy when navigating with a compass.

Together, these three types of north are critical when working with military maps, allowing personnel to accurately determine their location and navigate effectively across different terrains.
