has an accurate and detailed map.

The order gives such available information of the situation as is
necessary to the complete and proper guidance of subordinates;
designates the troops to constitute the supports; assigns their location
and the sector each is to cover; provides for the necessary detached
posts; indicates any special reconnaissance that is to be made; orders
the location and disposition of the reserve; disposes of the train if
same is ordered to join the outpost; and informs subordinates where
information will be sent.

After issuing the initial orders, the outpost commander inspects the
outpost, orders the necessary changes or additions, and sends his
superior a report of his dispositions.

The reserve is marched to its post by its commander, who then sends out
such detachments as have been ordered and places the rest in camp or
bivouac, over which at least one sentinel should be posted. Connection
must be maintained with the main body, the supports, and nearby detached
posts.

The supports march to their posts, using the necessary covering
detachments when in advance of the march outpost. A support commander's
order should fully explain the situation to subordinates, or to the
entire command, if it be small. It should detail the troops for the
different outguards and, when necessary, define the sector each is to
cover. It should provide the necessary sentinels at the post of support,
the patrols to be sent therefrom, and should arrange for the necessary
intrenching. Connection should be maintained with the adjoining supports
and with the outguards furnished by the supports.

In posting his command the support commander must seek to cover his
sector in such manner that the enemy cannot reach, in dangerous numbers
and unobserved, the position of the support or pass by it within the
sector intrusted to the support. On the other hand, he must economize
men on observation and patrol duty, for these duties are unusually
fatiguing. He must practise the greatest economy of men consistent with
the requirements of practical security.

As soon as the posting of the support is completed, its commander
carefully inspects the dispositions and corrects defects, if any, and
reports the disposition of his support, including the patrolling
ordered, to the outpost commander. This report is preferably made by
means of a sketch.

Each outguard is marched by its commander to its assigned station, and
especially in
