PART B - EVALUATE THE ENFORCING OF MINIMUM NOISE AND LIGHT DURING THE HOURS
OF DARKNESS AND THE PROPER DISPOSAL OF LITTER/TRASH
Noise
Learn to identify, evaluate, and react to common battlefield noises. Be aware of common sounds in
your area of operations. All sounds, the snap of a twig, the click of a bolt, the rattle of a canteen, the
bark of a dog, the call of the wild or domestic animals and fowl are information which could be valuable
to you.
You can learn a lot by listening. Train yourself to be patient. It may be necessary to listen in complete
silence for long periods.
Sounds can be heard better at night. This is because there are fewer noises to interfere and because
cooler, damper, night air carries sound better.
Remember sounds can reveal your presence to the enemy. Suppress a sneeze by pressing up on your
nostrils with your fingers. If you start to cough, squeeze your adam's apple slightly. If you cannot avoid
sneezing or coughing, muffle the noise by burying your nose and mouth in your hands or sleeve.
Secure and tape all metal parts, weapons slings, canteen cups, identification tags, and whatever else
you feel should be taped. Talking should only take place when it is necessary to conduct or explain
operations.
Use radios only when necessary. Keep the volume low so radios can be heard only by the operator.
Light Discipline
Smoking at night should be restricted. The enemy may see and smell it. If there is smoking, it should
only be where it can be concealed from enemy view.
Flashlights or other light sources must be filtered and concealed, such as under a poncho. Be sure that
you cover anything that reflects light such as metal surfaces, vehicles, glass, and many other things.
Litter Discipline
When occupying a position, take all litter such as empty food containers, empty ammo cans or boxes,
and old camouflage to established collection points. During movement, carry all litter until it can be
disposed of without leaving any trace of the unit's passage.
