How is the azimuth value typically expressed in navigation?

The azimuth value in navigation is primarily used to determine direction. It is expressed in degrees, which is a system of measurement that divides a circle into 360 parts. This is the most common way to represent azimuths because it aligns with how we typically measure compass directions.

Additionally, azimuths can also be expressed in mils, which is a unit of angular measurement used primarily in military applications. One mil corresponds to 1/6400 of a circle, providing a more precise means of measuring angles particularly useful in artillery and other military operations.

Thus, the correct choice reflects that azimuth values can be given in both degrees and mils, allowing navigators and military personnel to choose the unit that best suits their operational context.
