Which of the following is NOT one of the five major terrain features?

The five major terrain features commonly recognized in military map reading are hill, saddle, valley, ridge, and depression. These features provide critical information for navigation and positioning on the battlefield.

A river, while it is a significant geographic feature, is classified as a minor terrain feature rather than a major one. Major terrain features are characterized by their prominence and wide-ranging impact on movement and strategy, while rivers are important for terrain understanding but do not fall into the same category as the five major features recognized in military navigation.

Understanding the distinction between major and minor terrain features is crucial for effective land navigation and operational planning, as it helps soldiers to assess the terrain and make informed decisions during missions.
