explain Avoid ALL Unnecessary Movement
Remain motionless while observing. Anything in motion attracts the eye.
Use all available concealment because it offers a low silhouette and makes
detection by the enemy difficult.
Expose nothing that reflects light.
Blend with the background because contrasting colors are noticeable.
Remain in the shade because moving shadows attract attention.
Distort or change the regular outline of objects. Most military objects have
distinctive shapes that make obvious shadows and silhouettes.
Avoid the skyline. Figures on the skyline can be seen from great distances
and are easily identified by their outlines.
explain Search Fields of View
Off-center Vision Method
The technique of viewing an object using daytime central vision is ineffective
at night. This is due to the night blind spot that exists during low illumination.
Marines must learn to use off-center vision. This technique requires viewing
an object by looking 6 to 10 degrees above, below, or to either side of the
object rather than directly at it.
Scanning Method
Scanning enables the Marines to overcome many of the physiological
limitations of their eyes. It can also reduce confusing visual illusions. This
technique involves looking from right to left or left to right using a slow,
regular scanning movement as shown in figure 1. At night, it is essential to
avoid looking directly at a faintly visible object when trying to confirm its
presence.
Strip Method
In daylight, look first at the ground
nearest you. Begin observing close to
your post and search a narrow strip 50
meters or less deep, going from right to
left parallel to your front. Then search
from left to right a second and similar
strip farther away, but overlapping the
first. Continue to observe until the entire
field of view has been searched as
shown in the below figure.
explain Preserve Night Vision
When entering a lighted area or observing in a temporarily lighted area such
as illumination and flares, one eye should be closed and covered to preserve
its night vision.
When the light goes off, fades, or the lighted area is exited, the night vision
retained by the protected eye enables it to see until the other eye adapts to
the darkness.
Red light helps preserve night vision, but like white light, it can be observed
at long distances.
Factors that decrease night visual acuity include fatigue, lack of oxygen, long
exposure to sunlight, alcohol, nicotine within the past 48 hours, and age.
When night vision has been attained, straining will not improve effectiveness;
however, practicing to identify objects at night will improve perception.
explain Enhancing Hearing
Hearing is amplified with the mouth open.
Removing the helmet will reduce sound distortion.
By holding the ear close to the ground, sounds of people walking and
vehicles moving can be heard

and mission of adjacent units, and mission of non-organic supporting units
that may affect the actions of the unit.

by higher headquarters, including the effective time of attachment or
detachment.

Discuss the following hand and arm signals:Column Formation
- Raise either arm to the vertical
position. Drop the arm to the rear, describing complete
circles in a vertical plane parallel to the body. The signal
may be used to indicate either a troop or vehicular
column.
Discuss the following hand and arm signals:Echelon Left/Right -
The leader may give this signal
either facing towards or away from the unit. Extend one
arm 45 degrees below the horizontal, palms to the front.
The lower arm indicates the direction of echelon.
(Example: for echelon right, if the leader is facing in the
direction of the forward movement, the right arm is
lowered; if the leader is facing the unit, the left is
lowered.) Supplementary commands may be given to
ensure prompt and proper execution.
Discuss the following hand and arm signals:Skirmishers Left/Right -
- Raise both arms lateral until
horizontal, arms and hands extended palms down. If it is
necessary to indicate a direction, move in the desired
direction at the same time. When signaling for fire team
skirmishers, indicate skirmishers right or left by moving the
appropriate hand up and down.
The appropriate hand does not depend on the direction the signaler is facing.
Skirmishers left will always be indicated by moving the left hand up and down;
skirmishers right, the right hand.
Discuss the following hand and arm signals:wedge
Wedge Formation - Extend both arms downward and to
the side at an angle of 45 degrees below the horizontal,
palms to the front.
Discuss the following hand and arm signals: Fire Team
Fire Team - The right arm should be placed diagonally
across the chest
Discuss the following hand and arm signals: squad
Extend the hand and arm toward the squad leader,
palm of the hand down; distinctly move the hand up and
down several times from the wrist, holding the arm steady
Discuss the following hand and arm signals:Platoon -
Extend both arms forward, palms of the hands
down toward the leaders (or units) for whom the signal is
intended, and describe large vertical circles with hands.
Discuss the following hand and arm signals:Close Up
Start the signal with both arms extended
sideward, palms forward, and bring palms together in front
of the body momentarily. When repetition of this signal is
necessary, the arms are returned to the starting position by
movement along the front of the body
Discuss the following hand and arm signals:Open Up/Extended
Open Up/Extended - Start the signal with the arms
extended in front of the body, palms together, and bring the
arms to the horizontal position at the sides, palms forward.
When repetition of this signal is necessary, the arms are
returned along the front of the body to the starting position
and the signal is repeated until understood.
Discuss the following hand and arm signals:Halt/Stop
Halt/Stop - Carry the hand to the shoulder, palm to the front;
then thrust the hand upward vertically to the full extent of the
arm and hold it in that position until the signal is understood.
