The arms are stacked and the equipments (except cartridge belts) may
be removed. Roads communicating with the supports are opened.

When necessary, the outpost order states what is to be done in case of
attack, designates places of assembly and provides for interior
guards. Interior guards are posted in the camp of the reserve or main
body to maintain order, and furnish additional security. Additional
instructions may be given for messing, feeding, watering, etc. In the
vicinity of the enemy or at night a portion of the infantry may be
required to remain under arms, the cavalry to hold their horses
(cinches loosened), and the artillery to remain in harness, or take up
a combat position.

In case of alarm, the reserve prepares for action without delay, and
word is sent to the main body. In combat, the reserve reinforces the
line of resistance, and if unable to check the enemy until the arrival
of the main body, delays him as much as possible.

The distance of the reserve from the line of resistance varies, but is
generally about half a mile; in outposts of four companies or less
this distance may be as small as 400 yards.

=1064. Patrols.= Instead of using outguards along the entire front of
observation, part of this front may be covered by patrols only. These
should be used to cover such sections of the front as can be crossed
by the enemy only with difficulty and over which he is not likely to
attempt a crossing after dark.

In daylight much of the local patrolling may be dispensed with if the
country can be seen from the posts of the sentinels. However, patrols
should frequently be pushed well to the front unless the ground in
that direction is exceptionally open.

Patrols must be used to keep up connection between the parts of the
outpost except when, during daylight, certain fractions or groups are
mutually visible. After dark this connection must be maintained
throughout the outpost except where the larger subdivisions are
provided with wire communication.

The following patrols are usually sent out from the main bodies of the
supports:

(=a=) Patrols of from three men to a squad are sent along the roads
and trails in the direction of the enemy, for a distance of from one
to five miles, depending on how close the enemy is supposed to be,
whether or not there is any advance cavalry out, and how long the
outpost has been in position. The extreme right and left supports send
patrols well out on the roa
