Which north is NOT identified on a military map?

In the context of military maps, the north that is not identified is astrological north. Military maps primarily focus on practical navigation and orientation, and they utilize several standardized north indications such as true north, magnetic north, and grid north.

True north refers to the direction along the earth's surface towards the North Pole, which is essential for accurate navigation and is typically indicated by a line drawn on the map. Magnetic north, on the other hand, is the direction a magnetic compass points, which can differ from true north due to magnetic declination and is critical for real-time navigation using compasses. Grid north is aligned with the map's grid lines and is used to facilitate map reading and coordinate plotting.

Astrological north, however, is not a relevant or recognized concept in the context of military navigation or map reading. It does not apply to map orientation or practical navigation, which is why it is not identified on a military map.
