Q. What is meant by declination?
A. The angular distance between true north and either magnetic north or grid north.

Q. What is vertical distance?
A. The distance between the highest and lowest points measured.

Q. If a map is to be effective, what information is consulted?
A. Marginal data.

Q. Where is the legend of a map found?
A. Lower left margin.

Q. How is a lensatic compass held?
A. Level, firm and away from metals such as weapons and electrical devices.

Q. What is the basic rule for reading coordinates off a map?
A. Read right and up from the left hand corner.

Q. How close does an eight-digit coordinate locate a point?
A. To the nearest ten (10) meters.

Q. What does the graphic scale tell you?
A. It is the rule by which map distances can be measured as actual ground distance.

Q. Which north is used when using a military map?
A. Magnetic north when using a compass, and grid north when using the map.

Q. What is the name of the map system that the U.S. uses?
A. Universal Traverse Mecator (UTM) grid system.

Q. Land navigation demands application of what two basic rules?
A. Begin from a known point both on the ground and the map; orient the map to the ground and keep it oriented throughout the movement.

Q. What is an intersection?
A. Locating a distant or inaccessible feature on the map by shooting an azimuth from two known points towards this object. Where the lines cross on the map is the location of the object.

Q. What is resection?
A. A method of locating one's position on the map. Take azimuth readings to distant points on the ground that can be identified on the map, convert to back azimuth and grid azimuth and draw these azimuth lines for the known points on the map, where these lines intersect is your location.

Q. What are contour lines?
A. Imaginary lines on the ground connecting equal elevation.

Q. What are the three (3) types of contour lines?
A. Index, intermediate, supplementary.

Q. What is a contour interval?
A. The vertical distance between contour lines.

Q. What do 'U' or 'V' shaped contour lines mean?
A. A valley or draw.

Q. How can water flow be determined immediately on a map?
A. Where contour lines cross a stream they form a 'V' which will point upstream.

Q. What is the distance between grid lines on a combat map?
A. 1000 meters or 1 kilometer.

Q. What is a map overlay?
A. A map substitute, a piece of transparent plastic placed on a given map with certain items traced on them, reference grids drawn, name, date, or scale indicted used in conjunction with a map which does not already contain the overlay information.

Q. How many mils are there in a circle and what mil reading gives South-East?
A. 6400, 2400.

Q. What is a polar coordinate?
A. This is the method of plotting or locating an unknown point using an azimuth and distance from a known starting point.

Q. What are the three elements necessary for land navigation process known as dead reckoning?
A. Known starting point; Known distance; Known azimuth.

Q. What size unit is indicted by three dots?
A. Platoon or detachment.

Q. When colors are not available, how are symbols for enemy forces drawn?
A. Double lines.

Q. In military symbols, what colors are used for a map overlay, and what do they mean?
A.

Blue - Friendly forces.
Red - Enemy forces.
Green - Engineer obstacles, both friendly and enemy.
Yellow - Contaminated area, both friendly and enemy.
Black - Boundaries.

Q. What is meant by magnetic declination?
A. The variation of magnetic north from true north.

Q. What is a planametric map?
A. A map which portrays terrain and land forms in a measurable way as well as the horizontal features of the positions represented.

Q. What is a plametric map?
A. A map which represents only the horizontal positions of the features represented, for example like most road maps.

Q. What is a photo map?
A. A copy of an actual aeiral photograph or a mosaic made from a series of aerial photos upon which gridlines, marginal data, place names, route numbers, important elevations, scale and appropriate directions have been added.

Q. How do you measure distance using a road map?
A. Use the straight edge to compare the measurement of distance to mileage scale in the legend.

Q. What do topographic symbols represent?
A. Natural and man-made objects.

Q. Are topographic symbols drawn to scale?
A. No.

Q. What is longitude?
A. Imaginary lines that run north to south originating in Greenwich, England and measured in degrees.

Q. What does 1:25,000 on a map mean?
A. One unit of measurement of a map is equal to 25,000 of the same unit of measure on the ground.

Q. What precautions should be taken when using a compass?
A. Never read near masses of metal or electrical circuits.

Q. What type of compass does the infantry use?
A. The lensatic compass which provides a magnetic azimuth.

Q. Can a lensatic compass be used at night?
A. Yes, the dials and needles are luminous.

Q. Why is a map important?
A. When used correctly, a map can give accurate distances, locations, heights, best route, key terrain features, and cover and concealment information.

Q. How many scales are there on a compass?
A. Two.

Q. Name the five types of terrain found on a map.
A. Ridge, hilltop, valley, depression, and saddle.

Q. Name the minor terrain features found on a map.
A. Draw, spur and cliff.

Q. What is the quickest way to orient a map?
A. By use of a compass, place the compass on a map and align it with the grid lines with the needle indicting north.

Q. What is the best way to orient a map without a compass?
A. By aligning the map with the features on the ground.

Q. What is latitude?
A. The distance north or south from the equator.

Q. What are the four quadrants of a map?
A. Northeast, Southeast, Northwest, and Southwest.

Q. What is a bench mark?
A. A survey marker which indicates elevation.

Q. What is a back azimuth.
A. 180 degrees in the reverse of a measured azimuth.

A. Gray - alternate color for brown; Yellow - built up areas; Pink - political boundaries.
