In Polar Call For Fire, what unit is used for direction?

• A. Nearest 10 Mils
• B. Nearest 5 Mils
• C. Degrees
• D. Meters

Answer: (A)

Direction in Polar Call For Fire is given in mils, not degrees or meters. In this system, a circle is 6400 mils, so each mil is a tiny angular step (about 0.05625 degrees). The standard practice is to report the direction to the target to the nearest 10 mils. This level of rounding keeps communication clear and quick while still providing enough accuracy for aiming calculations and corrections. Degrees would require converting to mils for the fire direction, adding a potential source of error, and meters measure distance, not angle. So the direction unit is mils, specifically to the nearest 10 mils.
