The distance for live-fire baseline is measured in which unit?

• A. Nautical Miles
• B. Statute Miles
• C. Kilometers
• D. Meters

Answer: (A)

Distances for live-fire baselines are expressed in nautical miles. At sea, navigation and charting are built around nautical miles because one nautical mile corresponds to one minute of latitude, making range plotting, speed (knots), and course lines directly compatible with marine charts. This standard keeps measurements consistent across navigation, targeting, and safety boundaries during live-fire exercises. Using statute miles, kilometers, or meters would require unnecessary conversions and complicate coordination on naval charts.
