t the
sentry is aware of the position of the section and platoon commanders
and of the sentries on either side, and whether there are any patrols
or working parties out in front.

D. Every sentinel will report when an officer passes his post, "All is
well," or otherwise.

E. Every sentinel by day will be provided with a head-cover to blend
with the ground (this may be improvised), and while observing the
ground to the front will remain perfectly still. An empty sand bag or
some other suitable material may be utilized for this purpose.

3. Patrols.--A. It is the duty of all the troops holding the front
lines to establish a command of the ground in front of their parapet
up to the enemy's wire. This can be done by extended and constant
patrolling by night and reconnaissance by day so that the ground is
thoroughly well known to as large a portion as possible of officers
and men and so no enemy can move or remain in his front by night or
day without detection. One of the particular duties of these patrols
is to observe the condition of the wire entanglements.

B. Every patrol must have definite orders as to its mission; broadly
speaking, patrols may be divided into two classes: (1) reconnoitering
patrols, (2) fighting patrols.

C. The first duty of reconnoitering patrols is to obtain the
information for which they are sent out. They fight only in
self-defense or if any especially favorable opportunity arises to
inflict loss upon the enemy without prejudice to their mission. They
usually consist of two to six men, under an officer or
non-commissioned officer.

D. Fighting patrols are sent out for the express purpose of causing
loss or damage to the enemies by such means as engaging the enemy's
patrols or working parties, or by raiding saps, listening posts or
trenches. For identification purposes they should always endeavor to
secure at least one prisoner. Their strength depends upon the
resistance they are likely to meet with.

E. Company commanders are responsible for the orders given to patrols,
subject to any instructions which may be issued by higher authority.
They are also responsible that all troops, whom it concerns, including
companies on both flanks, are warned when and where patrols will be
out, length of time they will be out, and of the points to which they
will return.

F. Information gained by patrols is of little value unless transmitted
quickly to those whom it concerns. Patrol reports will be ma
