Duties Of A Patrol
Military Handbooks: The Plattsburg Manual Advanced Training
Each reconnoitering patrol is given a certain mission (duty) to perform.
The name, reconnoitering, meaning to survey, to view, indicates that
its first duty is to get information, and information is always greatly
increased in value if the enemy does not know it has been obtained.
Having obtained valuable information, its next duty is to send this
information to the officer sending out the patrol.
