How to Calculate Back Azimuth in MILS

What is the formula to find the back azimuth in MILS?

Choose the correct formula:

a. Add 6400 MILS to the forward azimuth

b. Subtract the forward azimuth from 6400 MILS

c. Multiply the forward azimuth by 2

Answer

The correct formula to find the back azimuth in MILS is to subtract the forward azimuth from 6400 MILS.

In military operations and land navigation, calculating the back azimuth is essential for determining the opposite direction of the forward azimuth. The back azimuth is crucial for planning movements, maintaining orientation, and ensuring accurate navigation.

When using MILS (or milliradians) to measure angles and directions, the formula to find the back azimuth is to subtract the forward azimuth from 6400 MILS. This calculation ensures that the back azimuth is accurately calculated based on the initial direction provided by the forward azimuth.

For example, if the forward azimuth is 3000 MILS, the calculation to find the back azimuth would be: 6400 - 3000 = 3400 MILS. This indicates that the back azimuth is 3400 MILS, representing the opposite direction of the initial forward azimuth.

By understanding and applying the formula to calculate the back azimuth in MILS, military personnel, surveyors, and navigators can enhance their navigation skills, maintain accurate bearings, and effectively plan their movements in the field.
