What type of angle is azimuth measured from a north baseline?

Azimuth is a measurement used to determine direction, typically expressed in degrees or mils. When azimuth is referenced in relation to a north baseline, the type of north being referenced is critical for ensuring accurate navigation and targeting.

True North, Grid North, and Magnetic North are essential concepts within this context. True North refers to the geographic North Pole, which serves as a fixed point in navigation. Grid North refers to the north direction based on the grid lines on a map, which can be crucial for map reading and navigation. Magnetic North, on the other hand, is determined by the Earth's magnetic field and is what a magnetic compass points to. Each of these references is vital for calculating azimuths accurately in various operational scenarios, especially in coordinating artillery and air support.

The inclusion of these specific types of north in the correct option underscores the importance of understanding geographic orientation in military operations, particularly in ensuring that azimuths are applied correctly relative to the earth's surface and magnetic variations.
