What are the three minor terrain features?

The correct choice identifies the three minor terrain features as cliff, spur, and draw. In military or tactical mapping, understanding terrain features is crucial for planning maneuvers and operations.

A cliff represents a steep rock face which can be a significant obstacle or cover. A spur is a prominent projection from a ridge that extends downhill, often providing a good vantage point or an access route to higher ground. A draw is a landform that has a small valley or depression leading down to a lower area, which can be useful for concealment or movement.

Recognizing these features allows military personnel to effectively leverage the terrain for strategic advantages, whether that’s for cover, movement, or identifying natural barriers. The other choices include terms that don't specifically categorize minor terrain features recognized in tactical contexts.
