The Army’s compass is similar in structure to the OSS’ compass.
U.S. Military forces have used this basic compass since the 1950s with only minor modifications. With its olive-drab aluminum case, sighting wire, magnifying eyepiece, and luminous dial, the compass enables the user to determine magnetic azimuths within an accuracy of 2 degrees. The folding scaled straightedge facilitates map orientation and line-of-sight plotting.
