What are military symbols?
Figures used to represent types of military organizations, installations, and activities
What are contour lines?
Imaginary lines on the ground connecting equal elevation, they represent high and low ground elevation.
What are 3 types of contour lines?
1. Index
2. Intermediate
3. Supplementary
How many Norths are there on a military map?
1. True north
2. Magnetic north
3. Grid north
What shape are the contour lines that indicate a hill?
A hill is shown on a map by contour lines forming concentric circles. The inside of the smallest closed circle is the hilltop.
What shape are the contour lines that indicate a saddle?
A saddle is normally represented as an hourglass
What shape are the contour lines that indicate a valley?
Contour lines forming a valley are either U-shaped or V-shaped.
What shape are the contour lines that indicate a Ridge?
Contour lines forming a ridge tend to be U-shaped or V-shaped. The closed end of the contour line points away from high ground.
What shape are the contour lines that indicate a depression?
Usually only depressions that are equal to or greater than the contour interval will be shown. On maps, depressions are
represented by closed contour lines that have tick marks pointing toward low ground.
What shape are the contour lines that indicate a draw?
The contour lines depicting a draw are U-shaped or V-shaped, pointing toward high ground.
What shape are the contour lines that indicate a spur?
Contour lines on a map depict a spur with the U or V pointing away from high ground.
What shape are the contour lines that indicate a cliff?
Cliffs are also shown by contour lines very close together and, in some instances, touching each other.
What shape are the contour lines that indicate a cut?
This contour line extends the length of the cut and has tick marks that extend from the cut line to the roadbed, if the
map scale permits this level of detail.
What shape are the contour lines that indicate a fill?
This contour line extends the length of the filled area and has tick marks that point toward lower ground. If the map
scale permits, the length of the fill tick marks are drawn to scale and extend from the base line of the fill symbol.
What are 5 major terrain features found on a map?
1. Hill
2. Ridge
3. Valley
4. Saddle
5. Depression
What are the 3 minor terrain features found on a military map?
1. Draw
2. Spur
3. Cliff
What are the 2 supplementary terrain features found on a military map?
1. Cut
2. Fill
What is a map?
A map is a graphic representation of a portion of the earth’s surface drawn to scale, as seen
from above.
What is an azimuth?
A horizontal angle, measured in a clockwise manner from a north base line, expressing direction.
What is vertical distance?
The distance between the highest and lowest points measured.
What is a contour interval?
The vertical distance between adjacent contour lines on a map.
Which north is used when using a military map?
Magnetic north when using a compass, and grid north when using the map
How would you hold a lensatic compass?
Away from metal (weapons, electrical devices), level and firm
Name two ways to hold a compass?
1. Compass-to-Cheek Method
2. Center-Hold Method
What is a declination diagram?
Shows the angular relationship between the magnetic north, grid north and true north
What is a benchmark?
A man-made marker showing points of elevation
What are parallels of latitude?
Measured distances going north or south of the equator
What does UTM stand for?
Universal Transverse Mercator
What is longitude?
Imaginary lines that run north to south originating in Greenwich, England and measured in degrees
What s a topographic map?
Portrays terrain and land forms in a measurable way as well as horizontal features of the positions represented
What is a small-scale map?
Those maps with scales of 1:1,000,000 and smaller are used for general planning and for strategic studies. The standard
small-scale map is 1:1,000,000. This map covers a very large land area at the expense of detail.
What is a medium-scale map?
Those maps with scales larger than 1:1,000,000 but smaller than 1:75,000 are used for operational planning. They
contain a moderate amount of detail, but terrain analysis is best done with the large-scale maps described below. The
standard medium-scale map is 1:250,000. Medium scale maps of 1:100,000 are also frequently encountered.
What is a large-scale map?
Those maps with scales of 1:75,000 and larger are used for tactical, administrative, and logistical planning. These are
the maps that you as a soldier or junior leader are most likely to encounter. The standard large-scale map is 1:50,000;
however, many areas have been mapped at a scale of 1:25,000.
What does the term intersection mean?
Finding the location of an unknown point by sighting two or more known points
Why is a map so important?
When used correctly, a map can give you accurate distances, locations and heights, best routes key terrain features and
cover and concealment information.
What does the term resection mean?
Resection is the method of locating one’s position on a map by determining the grid azimuth
to at least two well-defined locations that can be pinpointed on the map.
If you find a symbol on a map that is unknown to you, where would you look?
The marginal data, located on the outside lower portion of the map
How many scales are there on a compass, what are they?
1. Degrees
2. Mils
What are the 4 quadrants on a map?
1. Northeast
2. Southeast
3. Northwest
4. Southwest
What are the three elements for a land navigation process known as Dead Reckoning?
1. Known starting point
2. Known distance
3. Known azimuth
What is a polar coordinate?
Plotting or locating an unknown point using an azimuth and a distance from a known starting point
On a lensatic compass there are two rings, an outer black ring and an inner red ring, what are they used for?
The inner red ring is used to find degrees, and the outer black ring is used to find mils
Name 3 field expedient methods of determining direction
The shadow-tip method, the watch method, and the North Star method
What is a contour level?
It is the vertical distance between contour lines. The amount of the contour level is located in the Marginal Information on the map.
