Which of the following is NOT listed as a land navigation terrain type?

• A. Valley
• B. Hill
• C. Depression
• D. Ocean

Answer: (D)

In land navigation, you identify terrain features that appear on topographic maps to judge your position and plan routes. These features are landforms like hills, valleys, and depressions that influence slope, terrain roughness, and line of sight. An ocean, while important on maps for water navigation, is a body of water, not a landform. It isn’t categorized as a land navigation terrain type, so it doesn’t appear among the standard land features used to read terrain and navigate across solid ground. The other three—valley, hill, and depression—are common landforms you’ll encounter and use to understand the terrain you’re moving through.
