Which of the following is NOT a major terrain feature on a military map?

A canyon is not classified as a major terrain feature on a military map. Major terrain features typically include hills, saddles, and depressions, each of which has specific shapes and characteristics that are essential for navigation and understanding the landscape during military operations.

A hill is an elevated area of land that stands out from the surrounding terrain, crucial for establishing observation points. A saddle is a dip or low point between two higher areas, which can provide tactical advantages like movement routes. A depression indicates a sunken area on the map, which is important for understanding the contours of the land.

While canyons do represent significant topographical features, they are categorized more as minor terrain features due to their specific and narrow characteristics compared to the broader definitions of hills, saddles, and depressions. Understanding these classifications is important for effective map reading and tactical planning in military operations.
