On the military protractor, which scale is on the outer ring?

• A. Outer scale is mils
• B. Outer scale is degrees
• C. Outer scale is radians
• D. Outer scale is minutes

Answer: (D)

The outer ring is marked in arcminutes (minutes of angle). Each degree contains 60 minutes, so reading the bearing to the nearest minute gives finer precision than using degrees alone. This layout lets you quickly get a precise azimuth by looking at the outer ring while the inner ring provides the larger units (degrees or mils) depending on the model. In practice, you align the baseline with north on the map, and the outer ring’s arcminute marks give the exact reading needed for precise navigation or targeting.
