tem.= (Used with small or indistinct
targets.)

SYSTEM EXAMPLE

1. Announce the general direction "To our right front" (or "At two
of the reference point. o'clock").

2. Designate as a reference point "A stone house with two chimneys."
the most prominent object in the
zone indicated.

3. Announce the position of the "At three o'clock."
target with respect to the
reference point.

4. Announce the range. "Range 1000."

5. Announce the objective. "A hostile patrol of four men."

[Illustration: Fig. 53]

PROCEDURE:

1. All men look to their right front (or along the two o'clock line).

2. The reference point (stone house) is found in the indicated
direction.

3. A clock face (vertical) is imagined centered on the reference
point, and the men look along the line leading from the clock center
through three o'clock, and

4. 1000 yards from the firing point.

5. Find the hostile patrol.

=1447a. Finger System.= (Used with indistinct or invisible targets and
to define sectors.)

(By one "Finger" we mean the amount of frontage that one finger,
held vertically, will cover, the arm being extended horizontally
to its full length. In the average case this amount of frontage
covered is about 1/20 of the range. For instance, at a range of
1000 yards, one "Finger" will cover fifty yards of the sector The
same result will be obtained by using the rear-sight leaf in the
position of aiming.)

[Illustration: Fig. 54]

SYSTEM EXAMPLE

1. Announce direction to "To our right front, at 1000 yards."
reference point as in the
vertical clock face system.

2. Announce reference point. "A stone house with two chimneys."

3. Announce angular distance and "Four o'clock, three fingers."
direction from the reference
point to the target.

4. Announce range. "Range 1000."

5. Announce objective. "A skirmish line alongside of the
fence, length about two fingers,
right at the dark bush."

[Illustration: Fig. 55]

PROCEDURE:

The reference point is found as explained, and the vertical o'clock
line upon which the target will be found. The soldiers who do not see
the target will extend the aim to its _
