B. Principles: 

1.  Opportunity to “pick off” enemies ought to be ignored until
position of c.p. or s.s. or of its supporting body has
unquestionably been learned by enemy.  Then fire away.
2. Stop enemy’s patrolling.  Is as important as to force your
own observation.
3.  Advantages of s.s. over c.p. for night work:  (a) strength,
(b) sureness, (c) adequacy of observation before firing
alarm.
4.  Use of prisoners, and papers on dead bodies.
5.  Value of imagining yourself in position of enemy commander in
deciding what enemy dispositions you will combat him with.

Ninth Problem:  Reconnoitering Patrol: 

A. Definition and Function.—­Gather information in the field.  No resistance unless compelled.  Concealment and flight rather than resistance by fire:  opposite of “covering detachment.”

B. Principles.

1.  Judgment in deciding what equipment is appropriate to the
particular patrol.
2.  Sketch copies; contours as guides for concealed route.
3.  Fight only in self defence.
4.  How to question hidden sentinel without disclosing his
position to enemy.
5.  Judicious choice of cover in approaching destination.
6.  Dating and placing of messages.
7.  Rate of passage of troops:  “Rule of 2-2-2.”

Tenth Problem—­Visiting Patrol: 

A. Definition and Function: 

Two men or more sent from supports and pickets liaison between
adjoining outguards.  More useful at night, because of
reduced visibility of terrain between outguards.

1.  Inform the sending body of conditions at sentinel posts.
2.  Prevent enemy from penetrating lines between posts.
3.  Exchange information between adjoining posts.
4.  Take back captured strangers to commander.
5.  Reenforce feeling of mutual support among the isolated

      sentinels.

B. Principles.

1.  Keen sight and hearing; silence.
2.  Need of signals.  Both countersign and check—­countersign.
3.  Equipment; nothing that rattles or glistens.
4.  Disposition:  leader in front, because of need for quick
decision.
5.  Distance not over two miles even in most open country.
6.  Danger of startling a friend sentinel by unwarned approach.

Eleventh Problem—­Detached Post: 

A. Definition and Function.—­Posted where connection cannot be easily maintained with other elements of outpost.  Sent usually by outpost reserve or by main body, and retires to them, rather than to the line of supports.  Function same as element of outpost proper,—­observation, resistance, reconnaissance; but less resistance than warning.  May be as small as 2 men, or as large as a support, depending on location and importance of detached position.

B. Principles.
