A milliradian (mil) is an SI derived unit for angular measurement, defined as a thousandth of a radian (0.001 radian).
Compasses graduated in Milliradians are generally used where very small angles are necessary for very accurate calculation of proportions, size and distance of a target, for example for rifle and short distance artillery purposes.
A military compass is generally not suited for standard navigation for hikers, orienteers etc. where degrees are used to navigate.
