110 Tactical measures Flashcards
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.
Methods of searching field of view
Off center method
Scanning method
Strip Method
Off center 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.
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
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

Command and Signal
Special instructions on communications (prearranged signals) Password and countersign Radio call signs and frequencies Emergency signals Radio procedures Pyrotechnics Restrictions on the use of communications Location of patrol leader Location of assistant patrol leader
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 colum
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.
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.
Wedge Formation
Extend both arms downward and to the side at an angle of 45 degrees below the horizontal, palms to the front.
Fire team
Right armed placed diagonally across the chest
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
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
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.
Open up / Extend
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.
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.
