What are the three base directions or azimuths?

• A. True, Magnetic, Local
• B. True, Magnetic, Grid
• C. Grid, Local, True
• D. Magnetic, Local, Grid

Answer: (B)

The three base directions or azimuths are True, Magnetic, and Grid. True azimuth refers to the geographic direction based on true north, which corresponds to the North Pole. This is essential for navigation and is used in various mapping contexts. Magnetic azimuth is based on the magnetic north, which can differ from true north due to the Earth's magnetic field. This variation is important for compass readings as they can provide direction relative to the magnetic north rather than true north. Grid azimuths are based upon the grid system of a map, typically used in military contexts where maps are laid out with a grid. This type of azimuth is useful in determining direction over a map and for coordinating movements and actions based on precise locations. Understanding these three types of azimuths is crucial for accurate navigation and positioning in various environments, especially in military operations.
