Where is the legend of a map found?
Correct Answer
A. Lower left margin
Explanation
The legend of a map is typically found in the lower left margin. This is because the legend provides information about the symbols and colors used on the map, and placing it in the lower left margin makes it easily accessible for viewers to refer to while examining the map. Additionally, this location is often chosen because it is a common convention in map design, allowing for consistency and ease of use across different maps.

How many mils are in one degree?
Correct Answer
C. 17.7
3.
How many Norths are there on a military map?
Correct Answer
C. 3
Explanation
On a military map, there are typically three Norths indicated: True North, Grid North, and Magnetic North. True North is the direction towards the North Pole and is used for navigation purposes. Grid North refers to the north direction on the map's grid system, which is used to measure distances and locate points accurately. Magnetic North represents the direction towards the Earth's magnetic pole and is used for compass navigation. Therefore, the correct answer is 3, as all three Norths are important for military map reading and navigation.
4.
Which of the following are major terrain features?
Correct Answer(s)
A. Hill
C. Ridge
Explanation
Hills and ridges are major terrain features because they both refer to elevated areas of land. A hill is a rounded elevation that is lower and less steep than a mountain, while a ridge is a long, narrow elevated landform with a crest or top line. These features play a significant role in shaping the landscape and can have an impact on various aspects such as drainage patterns, vegetation, and human activities.
5.
Topographic maps are drawn to scale.
Correct Answer
B. False
Explanation
Topographic maps are not drawn to scale. These maps represent the three-dimensional features of the Earth's surface on a two-dimensional plane. They use contour lines to show elevation and depict various physical features such as mountains, rivers, and valleys. While topographic maps provide valuable information about the shape and characteristics of the land, they do not accurately represent distances or proportions. Therefore, they are not drawn to scale.
6.
Large cities on a map are represented by what color?
Correct Answer
B. Black
Explanation
Large cities on a map are typically represented by black color. This is because black stands out and provides a clear contrast against the other colors used on the map. Black is often used to indicate important or prominent features, and large cities are considered significant landmarks. Using black color for large cities helps users easily identify and locate them on the map.

How close will an eight-digit grid get you to your point?
Correct Answer
B. 10 meters
Explanation
An eight-digit grid will get you to your point within a range of 10 meters. The eight-digit grid refers to a coordinate system that uses eight digits to specify a location. Each digit represents a smaller unit of measurement, such as 10 meters. Therefore, by using this grid, you can determine your point's location with an accuracy of up to 10 meters.
8.
What terrain feature is highlighted in this graphic?
Correct Answer
D. Saddle
Explanation
The terrain feature highlighted in the graphic is a saddle. A saddle is a low point between two higher points, often resembling the shape of a saddle on a horse's back. It is characterized by a dip or depression in the landscape, connecting two higher elevations.
9.
How many sights does a compass have?
Correct Answer
B. 2
Explanation
A compass has two sights, which are the small notches or marks on its base that help in aligning the compass with a specific direction. These sights are used to accurately read the bearing or direction indicated by the compass needle. By aligning the sights with a distant object or landmark, one can determine the desired direction or navigate along a specific path. Therefore, the correct answer is 2.
10.
What are the types of contour lines?
Correct Answer(s)
A. Index
C. Supplementary
Explanation
Contour lines are used in topographic maps to represent the elevation of the land. The types of contour lines are index, supplementary, and secondary. Index contour lines are darker and labeled with the elevation value. They are usually every fifth contour line and help in identifying the elevation of the land quickly. Supplementary contour lines are lighter and are used to provide more detail between index contour lines. They help in understanding the shape and slope of the land. Secondary contour lines are even lighter and represent minor elevation changes. They provide further detail and help in understanding smaller features on the map.
11.
What terrain feature is highlighted on this graphic?
Correct Answer
D. Ridge
Explanation
The correct answer is ridge because a ridge is a long, narrow elevated landform that is higher than the surrounding terrain. It is often formed by the movement of tectonic plates or erosion processes. In the graphic, the highlighted feature appears to be a long, narrow elevated area, which is characteristic of a ridge.
12.
What are the 3 minor terrain features?
Correct Answer
A. Draw, Spur, Cliff
Explanation
The correct answer is Draw, Spur, Cliff. In military terrain analysis, a draw refers to a terrain feature that is characterized by a linear depression with sloping sides, often formed by water erosion. A spur is a terrain feature that projects outward from a ridge or high ground, typically with steep slopes on three sides. A cliff is a vertical or near-vertical feature that is formed by erosion or faulting, creating a significant drop in elevation. These three minor terrain features are important for military operations as they can provide cover, concealment, or obstacles for troops.
13.
What is the distance between grid lines on a combat map?
Correct Answer
B. 1000 meters
Explanation
The distance between grid lines on a combat map is typically 1000 meters. This measurement allows for accurate plotting and coordination of military operations, as it provides a reasonable level of detail while still being manageable for practical use in the field.
14.
What Does MGRS stand for?
Correct Answer
D. Military Grid Reference System
Explanation
The correct answer is Military Grid Reference System. MGRS is a system used by the military to accurately locate points on a map. It is a grid-based system that divides the Earth's surface into smaller grids, allowing for precise identification of locations. This system is widely used by military personnel for navigation, targeting, and communication purposes.
15.
What does the term intersection mean?
Correct Answer
A. Finding the location of an unknown point by sighting two or more known points
Explanation
The term intersection refers to the process of determining the location of an unknown point by sighting two or more known points. This method is commonly used in surveying and navigation to establish the position of a point by triangulation or by using other known reference points. By measuring angles or distances from the known points, the intersection can be calculated to determine the location of the unknown point accurately.
