Land navigation, or orienteering, is the military term for the study of traversing through unfamiliar terrain by foot or in a land vehicle. Land navigation includes the ability to read maps, use a compass, and other navigational skills. Land navigation courses are an essential part of military training. Often, these courses are several miles long in rough terrain and are performed under adverse conditions, such as at night or in the rain. In the late 19th century, land navigation developed into the sport of orienteering.
