In the Five Rules of Direction, which element is Mils preferred?

• A. Mils
• B. Degrees
• C. Grid
• D. Seconds

Answer: (A)

Mils are preferred for direction because they provide precise, rapid adjustments that align with how artillery fire direction and field instruments operate. A full circle is 6,400 mils, so each mil is a small, easy-to-handle increment. This means small corrections translate to small, predictable changes in aim—for example, at typical ranges, 1 mil is about 1 meter of lateral shift per 1,000 meters of range. That lets you make accurate, quick bearing changes without needing to convert between units. Degrees, gridded references, or seconds introduce conversions, coarser steps, or impractical timing for a fire mission, making mils the most practical choice for direction.
