LESSON THREE

PRACTICE EXERCISE

ANSWER KEY AND FEEDBACK

Situation: You are a member of a fighting force engaged in combat operations in the desert. Therefore, it is vital that you know tactics for desert operations.

1. You are called to a meeting to discuss tactics for a pending campaign in a desert environment. The objective of your unit operations is to
  A. dominate terrain from which you can pin down and destroy the enemy.

The objective of unit operations is to destroy the enemy. Since key terrain features are scarce in the desert, units rarely seize or retain them. Hot, barren mountains are not a good environment for tracks, because they can't maximize their mobility, flexibility and firepower. Your unit must maneuver at maximum tactical speed permitted by terrain and dust conditions. You may want surprise by maneuvering at night, behind smoke or during dust and sand storms.

  B. seize and retain as many terrain features as possible.
  C. maximize tank and armored cavalry mobility, flexibility and firepower in hot, barren mountains.
  D. maneuver at measured tactical speeds only during periods of clear visibility.
2. After maneuvering to your objective, you need to establish observation posts. You tell your OPs
  A.

to inspect the positions from the enemy's point of view to maximize cover and concealment.

When preparing your defensive positions, you need to inspect them from the enemy point of view to ensure that available cover and concealment are maximized. An OP on dominant terrain can see dust clouds from helicopters from 20-30 kilometers, and easily identify vehicle columns at more than five kilometers. Observation of direct fires may be difficult, since high-velocity direct fire can throw up considerable dust clouds. Forward observers should place initial rounds beyond a target because there may be dust hanging in the air following the impact of ranging rounds.

  B. to disregard dust clouds which are mirages at more than five kilometers away.
  C. there should be no problem observing direct fires in the desert.
  D. to place initial rounds short of the target to blind the enemy.
3. After briefing your OP's, you set up additional reconnaissance and security measures. Your major means of reconnaissance is
  A. dismounted infantry.
  B. ground scouts.
  C. air calvary.

Your major reconnaissance means is air cavalry, although they must guard against being ambushed by ground troops located at their own altitude or even higher. Ground scouts normally move two to four kilometers to the front or flanks of leading teams. The distance allows time for squads to dismount observers. You drop off your OP at some distance from the designated position, preferably by helicopter at night. The observers go the rest of the way on foot to minimize enemy observation.

  D. observation posts.
4. Your navigation mainly depends on available maps. You also take into consideration that
  A. radar devices are limited to night time use.
  B. sun compasses are less reliable on moving vehicles than lensatic compasses.
  C. gyro compasses can be used as gun azimuth stabilizers for maintaining direction.

The gyro compass is an efficient gun azimuth stabilizer, because it's a gyroscope and can be used for maintaining direction on fairly flat ground. Radars can be used during midday heat haze on flat terrain if optical vision is hopelessly distorted. Sun compasses can be used on moving vehicles, whereas lensatic compasses are unreliable near metal, and almost impossible to use with accuracy on a vehicle. RF beacons and homers also can permit the enemy to locate friendly forces, so you may have to place them in wide open desert with unit locations marked by distances and bearings. A pocket altimeter measures your altitude.

  D. RF beacons and homers must be co-located with friendly forces on high ground.
5. To prevent casualties from friendly fire and identify friendly forces, you
  A. ensure IFF procedures for ground troops are more thorough than aircraft IFF.
  B. use colored pennants in different daily positions, but not attached to antennas.

Identification Friend or Foe (IFF) is a problem for ground troops and even more difficult for aircraft. National identifying marks are not sufficient, so you need to have a thorough knowledge of the vehicles used by both the enemy and allied forces. The force should have a standing IFF operating procedure that allows for daily changes. You can use systems that include:

  • Tape markings, white or multicolored.
  • Colored pennants in different daily positions. Don't fly these from antennas as they may degrade radio performance. Unless all vehicles carry them, they may assist the enemy to identify headquarters vehicles. They may be of negligible value in very dusty conditions.
  • A commonly known radio frequency for IFF only.
  • You need to check communications from a newly selected position before you move headquarters. Liaison officers or messengers are used if units are stationary or under listening silence.

      C. never broadcast radio transmissions in areas previously held by the enemy until you have moved headquarters.
      D. use liaison officers or messengers for units on the move.
    6. You improve tactical advantage with deception operations. One deception method you should use in desert warfare is to
      A. move around and vary the locations of dummy supply stocks and wheel tracks daily to simulate a POL installation.

    You can conceal operational plans from the enemy with dummy installations such as a POL supply point with dummy supply stocks and wheel tracks moved daily. You were warned not to emplace live mines in a phony mine field. You can construct field artillery decoys without simulators with various methods such as suspending explosive charges or using photoflash. Personnel can man dummy positions to simulate activity and to obtain counterfire intelligence. They should have foxholes for protection.

      B. emplace live mines to improve credibility of a phony minefield.
      C. construct field artillery decoys only when simulators are available.
      D. vacate your dummy positions as soon as possible.
    7. The single most important mission of engineers in desert operations is
      A. preposition field artillery pieces for long-term indirect fire.
      B. locate air Defense Artillery as far away as possible from its supported unit to confuse enemy ECM.
      C. water supply.

    Engineers have the single most important mission of water supply in the desert. Field artillery pieces must be as mobile as the force they are supporting, and be proficient in direct fire. Air defense artillery must be located close to the units they are supporting so they can have ground defense. Military Police direct traffic at circulation control points increasingly required by the indefinite conditions and number of roadways.

      D. direct traffic in the wide-open desert.
    8. Combat Service Support can have complications in the desert. A factor you need to be aware of is
      A. the minimum demand for water is ten gallons per day per man.
      B. since air transportation is unlimited, keep your wheeled supply vehicles as far to the rear as possible.
      C. combat boots may last only two weeks in harsh rocky terrain.

    Combat boots may be expected to last approximately two weeks in harsh rocky terrain. The minimum demand for water is approximately nine quarts per day per man. Air transportation may be limited by weather, enemy activity or scarcity of landing sites.

    You should employ wheel vehicle transportation as far forward as possible. Medical evacuation can be complicated by long and limited routes, or lack of facilities or water. You may require teams of stretcher bearers to the nearest landing site.

      D. you can expect relatively easy medical evacuation by air.
    9. You must plan methods of defense against the enemy in desert terrain. A very possible factor is
      A. the enemy prefers frontal attacks with swarms of infantry.
      B. when a motorized rifle division attacks in two echelons, a tank regiment brings up the rear in second echelon fire support.
      C. the enemy frequently uses smoke screens to confuse the defender.

    The enemy uses smoke to confuse the defender. The enemy avoids frontal attacks. His forces operating in the desert are predominantly armored. A tank regiment is likely to be in the first echelon of a motorized rifle division attack. Enemy forces expect meeting engagements to be decisive, and uses breakthrough attacks against forces he cannot directly defeat.

      D. the enemy plans meeting engagements as harassment against forces he cannot directly defeat.
    10. During pursuit of the enemy in desert operations, you can expect
      A. the enemy to use nuclear or chemical strikes only after conventional fires have failed.
      B. a second echelon of airborne enemy troops to join enemy forces.
      C. the enemy not to attack retrograde operations.
      D. enemy forces to have a tank battalion operating 60 kilometers ahead of the main body avoiding combat until reaching a designated objective.

    An independent tank battalion operating 60 kilometers ahead of the main body has limited endurance and usually avoids sustained combat until reaching its designated objective. If used, nuclear or chemical strikes are made by the enemy immediately before conventional preparatory fires. The enemy does not often commit airborne troops within a brigade area except in support of nuclear strikes. They usually are used on much deeper objectives, for example, a lodgement area. The enemy will pursue any indication of retrograde operations and maintain pressure without further orders.

    11. You must anticipate what kind of defense a desert-warfare enemy is likely to throw up. You can expect
      A. a hasty defense of company-size strong points along flanks of an advance.

    The enemy conducts a hasty defense when protecting the flanks of an advancing division. The enemy makes a deliberate defense when it is clear the attack cannot continue for several hours. A security zone extends forward of the main defense belt. Forward positions likely will retrograde if it looks like they will be encircled. The enemy defends at night, and will use white light freely when an attack has started.

      B. a deliberate defense along a continuing attack and kill zone with a second-echelon security zone.
      C. forward positions that will fight to the last man.
      D. the enemy to maintain white-light discipline throughout the defense.
    12. A "lesson-learned" tip on fighting in the desert is
      A. scouts must blast their way through strongpoints.
      B. you must move vehicles and equipment as the sun moves.

    You must move equipment as the sun moves. Scouts are not combat patrols, and should attempt reconnaissance information through stealth. Extended depth and dispersion will increase your chances of survival. Engineers should reconnoiter routes of march to avoid needless destruction of roadways, bridges, and pipelines. Everybody should know the commander's intent and rehearse battle drill, so everybody understands actions in the absence of good communications.

      C. grouping together for "strength in numbers" will enhance your chance of survival.
      D. along your route of march, destroy as many roadways, bridges and pipelines as possible.
