Guide

Sometimes people are hard to spot or track, making range estimation using body dimensions difficult. At long ranges, smaller objects require a more accurate reading of mrads, which is error-prone. Other larger objects, including identifiable vehicles, lend themselves to the same purpose.

  • A BTR-80 is 2 metres from the ground to the top of the hull, appearing as 4 mrad in our scope:
    • ((Ground to top of BTR hull) * 1000) / (mrad measured) = (range in metres)
    • (2 m * 1000) / 4 mrad = 2000 / 4
    • = 500 metres

Sometimes personnel is hard to spot or track, making range estimation using body dimensions difficult. Especially at long ranges, smaller objects require a more accurate reading of mrads, which is error-prone. Other larger objects, including identifiable vehicles, lend themselves to the same purpose.

A BTR-80 is 2 metres from the base of its wheels to the top of the hull, appearing as 4 mrad in our scope:

((BTR wheel to roof) * 1000) / (mrad measured) = (range in metres)

(2 m * 1000) / 4 mrad = 2000 / 4

= 500 metres
