Which major terrain feature is characterized by a high point of land?

A hill is identified as a major terrain feature characterized by a high point of land. It is typically defined as a natural elevation that rises above the surrounding terrain, which is important for various tactical considerations in military operations, such as observation, cover, and concealment. Hills can provide a strategic advantage as they offer a commanding view of the area around them, making them critical in planning and executing maneuvers.

In contrast, the other options represent different terrain features: a valley is a low area between hills or mountains; a saddle is a dip or low point between two higher elevations, and a depression is a sunken or low-lying area. These features, while important in understanding the terrain, do not convey the essence of a high point of land like a hill does.
