Spot your location on your map and relate it to the surrounding terrain. This is a basic principle that you must always follow. If there are other persons with you, make sure they also know their location. Always know who in your group, vehicle or aircraft has a map and compass. If that person is killed, you will have to get the map and compass from him. Pay close attention to where you are and to where you are going. Do not rely on others in the group to keep track of the route. Constantly orient yourself.
Always try to determine, as a minimum, how your location relates to —
* The location of enemy units and controlled areas.
* The location of friendly units and controlled areas.
* The location of local water sources (especially important in the desert).
* Areas that will provide good cover and concealment.
This information will allow you to make intelligent decisions when you are in a survival and/or evasion situation.
