“ Observation varies from good to poor depending on trees and scrub growth. Surveillance sites near ridges and peaks may provide broad areas of observation. Aircraft movement of teams is often limited by altitude capability, erratic wind conditions, and lack of landing sites. Communication is generally difficult; relay stations may be needed for communication between the teams and base stations. ”

“ JUNGLE OPERATIONS Operations in dense jungle increase the importance of LRS teams because of restricted ground and air observation, including electronic surveillance systems. Human intelligence sources can become the primary source of battlefield information in this terrain. ”

“ Weapons should not be oiled until needed for combat. Oil attracts sand, which causes jams. To fight rust and sand, weapons must be cleaned daily. (5) The minimum desert uniform is the desert battle dress uniform with sleeves down, floppy hat, sunglasses, and a scarf. All clothing should be worn loosely. Socks should be changed when they become wet or at least daily. Soldiers should use the buddy system to supervise each other to avoid desert-related injuries. ”

“ Soldiers must drink water at regular intervals to help remain cool and keep sweating reduced. Even if water supplies are low, soldiers can constantly sip water. (a) Thirst is not a reliable guide for the body's need for water. Thirst only accommodates two-thirds of the daily requirement. Soldiers should drink at least one-half a quart of water every hour. If the temperature is over 100 degrees Fahrenheit, soldiers should drink one quart of water every hour. They should drink a quart of water with each meal. If there is not enough water, soldiers should not eat. ”

“ Because terrain features are few and maps are not accurate, soldiers should use a global positioning system. (c) Teams should walk on rocks and shale to aid in counter tracking. (d) Teams can move faster on wet or dark sand; loose or dune sand demands slower movement. (4) Hide or surveillance site. (a) Teams should use diamond desert camouflage nets to construct hide or surveillance sites. (b) Teams should establish hide and surveillance sites together because of unlimited observation. (c) Teams must conduct surveillance from a point higher than the named area of interest ”

“ During the hottest periods of the day, soldiers should remain quiet and stay out of the sun. Excess movement causes water loss through sweating. The first measure is to get out of the sun. Soldiers should not sit directly on desert sand or rocks. The ground is 20 degrees hotter than the air. Soldiers should sit under man-made shade, if necessary. ”

“ Dense vegetation, high humidity, and frequent rainfall make HF communication difficult. The vegetation affects radio range and makes antenna erection more difficult. Radio components experience higher failure rates in wet environments. ”

“ Teams operating in these areas are greatly affected by adverse weather and terrain conditions. Extremes in temperature, humidity, and elevation also have considerable effect on the lift capability of transporting aircraft. ”

“ The normal body temperature is 98.6 degrees Fahrenheit. Excess sweating reduces body water content; therefore, water discipline must be enforced in an arid environment to maintain the body's fluid level. ”
