Military Map Reading 5 — Questions and Answers
Question 1: What does the term 'relief' refer to on a military topographic map?
- The map's color scheme
- The variation in terrain elevation depicted by contour lines (Correct answer)
- The distance between grid lines
- The map's publication date
Correct answer: The variation in terrain elevation depicted by contour lines
Relief refers to the differences in terrain elevation, typically represented by contour lines on a topographic map.
Question 2: Which military map scale provides the MOST detail for a small area?
- 1:250,000
- 1:100,000
- 1:50,000
- 1:25,000 (Correct answer)
Correct answer: 1:25,000
A 1:25,000 scale map provides the greatest detail because the ratio is smallest, meaning less compression of real-world features.
Question 3: In the MGRS system, what does the two-letter 'Grid Zone Designator' square identifier represent?
- The country and military zone
- A 100,000-meter square within a Grid Zone (Correct answer)
- The specific 10-meter grid cell
- The hemisphere and latitude band
Correct answer: A 100,000-meter square within a Grid Zone
The two-letter identifier in MGRS designates a specific 100,000-meter square within a larger Grid Zone Designator.
Question 4: When orienting a map to the ground using terrain association, what is the primary method?
- Aligning the map's north arrow to a compass
- Matching terrain features visible on the ground to those on the map (Correct answer)
- Using the GPS coordinates on the map edge
- Counting grid squares from the last known point
Correct answer: Matching terrain features visible on the ground to those on the map
Terrain association involves rotating the map so that features on the map align with corresponding features visible on the ground.
Question 5: A 'draw' differs from a 'valley' primarily in that a draw is:
- Wider and longer
- A smaller, less developed drainage feature (Correct answer)
- Entirely man-made
- Always found on flat terrain
Correct answer: A smaller, less developed drainage feature
A draw is a smaller, shallower drainage feature compared to a valley, often the starting point of water flow.
Question 6: What information does the 'bar scale' on a military map provide?
- The map's elevation range
- A visual ruler showing the relationship between map distance and ground distance (Correct answer)
- The grid zone boundaries
- The contour interval used
Correct answer: A visual ruler showing the relationship between map distance and ground distance
The bar scale is a graphic ruler printed on the map that allows direct measurement of ground distances using the map.
Question 7: Which technique is most appropriate when you need to navigate precisely through dense terrain with limited visibility?
- Terrain association at speed
- Deliberate offset navigation
- Pace count and compass bearing (dead reckoning) (Correct answer)
- Visual resection from high ground
Correct answer: Pace count and compass bearing (dead reckoning)
Dead reckoning using pace count and compass bearing is the most reliable technique for precise navigation in low-visibility, dense terrain.
