key to the types of items you will need in your survival kit. How much equipment you put in your kit depends on how you will carry the kit. A kit carried on your body will have to be smaller than one carried in a vehicle. Always layer your survival kit, keeping the most important items on your body. For example, your map and compass should always be on your body. Carry less important items on your load-bearing equipment. Place bulky items in the rucksack.
In preparing your survival kit, select items you can use for more than one purpose. If you have two items that will serve the same function, pick the one you can use for another function. Do not duplicate items, as this increases your kit's size and weight. Your survival kit need not be elaborate. You need only functional items that will meet your needs and a case to hold the items. For the case, you might want to use a Band-Aid box, a first aid case, an ammunition pouch, or another suitable case. This case should be-
• Water repellent or waterproof.
• Easy to carry or attach to your body.
• Suitable to accept varisized components.
• Durable.
In your survival kit, you should have-
• First aid items.
• Water purification tablets or drops.
• Fire starting equipment.
• Signaling items.
• Food procurement items.
• Shelter items
Some examples of these items are-
• Lighter, metal match, waterproof matches.
• Snare wire.
• Signaling mirror.
• Wrist compass.
• Fish and snare line.
• Fishhooks.
• Candle.
• Small hand lens.
• Oxytetracycline tablets (diarrhea or infection).
• Water purification tablets.
• Solar blanket.
• Surgical blades.
• Butterfly sutures.
• Condoms for water storage.
• Chap Stick.
• Needle and thread.
• Knife.
Include a weapon only if the situation so dictates. Read about and practice the survival techniques in this manual. Consider your unit's mission and the environment in which your unit will operate. Then prepare your survival kit.

Requirements for Maintenance of Health
To survive, you need water and food. You must also have and apply high personal hygiene standards.
Water
Your body loses water through normal body processes (sweating, urinating, and defecating). During average daily exertion when the atmospheric temperature is 20 degrees Celsius (C) (68 degrees Fahrenheit), the average adult loses and therefore requires 2 to 3 liters of water daily. Other factors, such as heat exposure, cold exposure, intense activity, high altitude, burns, or illness, can cause your body to lose more water. You must replace this water.
Dehydration results from inadequate replacement of lost body fluids. It decreases your efficiency and, if injured, increases your susceptibility to severe shock. Consider the following results of body fluid loss:
• A 5 percent loss of body fluids results in thirst, irritability, nausea, and weakness.
• A 10 percent loss results in dizziness, headache, inability to walk, and a tingling sensation in the limbs.
• A 15 percent loss results in dim vision, painful urination, swollen tongue, deafness, and a numb feeling in the skin.
• A loss greater than 15 percent of body fluids may result in death.
The most common signs and symptoms of dehydration are-
• Dark urine with a very strong odor.
• Low urine output.
• Dark, sunken eyes.
• Fatigue.
• Emotional instability.
• Loss of skin elasticity.
• Delayed capillary refill in fingernail beds.
• Trench line down center of tongue.
• Thirst. Last on the list because you are already 2 percent dehydrated by the time you crave fluids.
You replace the water as you lose it. Trying to make up a deficit is difficult in a survival situation, and thirst is not a sign of how much water you need.
Most people cannot comfortably drink more than 1 liter of water at a time. So, even when not thirsty, drink small amounts of water at regular intervals each hour to prevent dehydration.
If you are under physical and mental stress or subject to severe conditions, increase your water intake. Drink enough liquids to maintain a urine output of at least 0.5 liter every 24 hours.
In any situation where food intake is low, drink 6 to 8 liters of water per day. In an extreme climate, especially an arid one, the average person
