How many types of North are there on a military map?

On a military map, there are three types of north: true north, magnetic north, and grid north.

True north refers to the direction along the earth's surface towards the geographic North Pole. It is a fixed point that is fundamental for navigation and mapping.

Magnetic north is the direction that a magnetic compass points, which is influenced by the Earth's magnetic field. This can vary based on the location and changes over time due to shifts in the Earth's magnetic field.

Grid north refers to the north direction from the grid lines on a map, which typically align with the edges of the map and are used in conjunction with map scale and coordinates for navigation.

Understanding these three types of north is crucial for accurately interpreting military maps and ensuring precise navigation in various operational scenarios.
