What two scales does the military protractor contain?

• A. degrees (inner scale) mils (outer scale)
• B. degrees (outer) and radians (inner)
• C. mils (inner) and degrees (outer)
• D. Degrees only

Answer: (B)

A military protractor is designed to give you two useful ways to read angles at a glance. The outer edge is marked in degrees, which is the common, intuitive way to measure angles around a circle and is frequently used in navigation and targeting. The inner edge is in radians, a mathematical unit that aligns with trigonometric calculations. Having both scales lets you read or convert an angle quickly between degrees and radians without doing manual conversion, speeding up field calculations. Options that pair degrees with a different unit on the inner scale would not match the instrument’s common dual-use design, and offering degrees alone would omit the second scale entirely.
