How many major terrain features are identified on a military map?

The correct answer identifies that there are five major terrain features recognized on a military map. These features are essential for navigation and understanding the landscape in military operations. The five major terrain features are hills, valleys, ridges, depressions, and level areas. Each of these features plays a critical role in determining tactical advantages or challenges during military maneuvers.

Understanding these features is crucial for effective planning and execution of military strategies. For example, hills provide high ground, which can be advantageous for observation and defense, while valleys may serve as routes for movement or potential ambush locations. By knowing these five features, military personnel can better analyze the terrain and make informed decisions during operations.

The other options do not accurately reflect the comprehensive categorization of terrain features as defined in military mapping, leading to gaps in understanding for those studying military tactics and navigation.
