LESSON 2
PRACTICE EXERCISE

Instructions The following items will test your knowledge of the material covered in this lesson. There is only one correct answer for each item. When you have completed the exercise, check your answers with the answer key that follows. If you answer any item incorrectly, study again that part of the lesson that contains the portion involved.
Situation: You have deployed along a demilitarized zone somewhere in a desert of the Middle East. It is vital you know desert camouflaging, personnel and equipment, and preparation.

1. Your brigade of tracked vehicles is told to set up a long-term bivouac in desert terrain. You instruct your troops in the below-ground shelter method which

 A. reduces mid-day heat as much as 50 degrees Centigrade.
B. should be constructed during mid-day pause in operations.
C. reduces the midday heat as much as 30 to 40 degrees Fahrenheit..
D. is protected from accidental run over by a tank by securing the cover with a rigid center-pole mast.
2. Your desert outpost has little cover and concealment from lack of heavy vegetation and your immediate concern is to eliminate the shine reflecting off some vehicle components. Since there is an engineer company nearby, you tell your troops to

A. use dozer blades for constructing geometrical angles of radar-reflecting sangars approximately three meters high around vehicles.
B. use cranes and winches that erect camouflage nets for total concealment from air reconnaissance.
C. use mine-clearing rollers to break up the hardest ground so helicopters can fly Nap-Of-the-Earth.
D. use matte camouflage paint, grease and sand to smear on vehicles and see through cloth to attach on vehicle windshields.
3. Your tanks are equipped with smoke dischargers. A factor concerning smoke generation is

A. smoke blinds enemy radar during periods of high ambient temperature.
B. the best conditions for employment of smoke are at mid-day with turbulent air conditions.
C. a large-area smoke screen normally requires prestocking of smoke ammunition for artillery or mortars.
D. a tank fires local smoke as a stop gap when attacking from its camouflaged hull-down position.
4. An important guideline concerning your brigade assets is
A. aircraft are relatively hard to conceal because of their heat signature and maintenance requirements.
B. your field artillery battery requires a long-lead time for static defensive positioning and ammunition requirements.
C. your ADA unit relies on mobility and use of "mushrooms" above radars.
D. engineer activity follows operations with equipment kept in line for rapid maximum convoy deployment.
5. An important factor of weapons maintenance in a desert environment is

A. working parts of weapons should be kept well lubricated.
B. artillery ammunition is consumed in smaller quantities because precision targeting is possible in open terrain.
C. gun-tube bend totally distorts accuracy, causing rounds to fall short, and making it necessary to resight the bore.
D. optics never should be covered with a plastic trash bag since if glass does not "breathe" it may crack.
6. You notice your personnel are fatigued and irritable under desert conditions. Therefore, you conclude

A. you need to "cool out" on discipline, "lighten up" on physical training and be tolerant of irregular snacking on "junk food."
B. those personnel hit by climatic stress are more adversely affected by lack of proper acclimatization, overweight, dehydration, alcoholic excess, lack of sleep, old age, and poor health.
C. you can shorten acclimatization time to a few days by shedding excess clothing while exercising during the hotter hours.
D. you will have to advise your men that a loss of a quart of body fluid decreases efficiency by half.
7. To maintain proper personal hygiene standards when water is limited and to deterrent disease in desert environments, it important that

A. you can never get too much salt.
B. sunglasses are out of uniform, and unless they are prescription, should not be permitted to degrade discipline.
C. you must clean the areas of your body that sweat heavily; change underwear frequently, and use foot powder often.
D. you can't worry about losing a little sleep over night operations when it's cooler.
8. Your brigade requires high-speed reconnaissance over an area of little trafficability. Therefore, you

A. send out your wheeled scouts because they are best suited for a much higher average speed in poor terrain.
B. tell the operators to immediately stop engines if a temperature gauge reaches 200 degrees at high speeds.
C. tell the drivers to open hood panels for better engine cooling during hot weather.
D. must have alternate ways to communicate, especially if noon is approaching and you start to lose radio contact.
9. In preparing for desert operations, you need to take into consideration what equipment is prone to malfunction. However, equipment that is LESS likely to be a maintenance problem in the desert is

A. rubber items such as tires which stay preserved better in dry climates.
B. batteries which actually hold their charge better much like static electricity.
C. helicopters and tanks.
D. a U.S. Dodge truck (with a skill driver) made for use on blacktop.
10. Individual training for desert operations includes how to survive. You instruct your troops that
A. survival training does more than almost anything else to build morale and strengthens self-confidence.
B. wells in a Middle-East war most likely will be poisoned.
C. navigation training means familiarization with the celestial arts.
D. when evading or escaping, get rid of your weapon where it won't be tracked down by the enemy.
11. You are tasked with your unit's training schedule for a field exercise in the desert. For correct advise, you call on
A. your unit surgeon who stresses his role to minimize casualties, due to lack of consideration of preventive medicine concepts that can far outnumber combat casualties.
B. Your NBC specialist who emphasizes the need to avoid being uncomfortable in hot environments at all costs.
C. An intelligence officer who explains how not to waste effort on security after deception.
D. a communications-electronics NCO who points out special ECCM peculiar to desert operations, such as first interrogating the net for a "hot microphone" during jamming.
12. Your unit is being evaluated in a training mode. You insist on
A. regular close-interval spacing while convoying over open terrain.
B. gunners to expect more first-round hits due to the open terrain.
C. assuming enemy air superiority during all field training.
D. parking all vehicles lined up in a designated parking area away from the TOC.
