What are the supplemental terrain features found on a military map?

The correct answer is rooted in an understanding of the specific terminology used in military maps. Supplemental terrain features are additional elements depicted to enhance the primary features, giving a more comprehensive picture of the terrain.

In this context, "Cut" refers to an area where the ground has been lowered, such as in road construction, while "Fill" indicates an area where the ground has been raised by adding material, again often seen in construction or alteration of landscapes. These features are important for soldiers to understand when analyzing how the terrain might affect mobility, visibility, and tactical planning.

The other options, while they do describe various landforms or features, do not fit into the category of supplemental terrain features. Hills and valleys are primary landforms, draws and spurs relate to slope definitions, and cliffs and ridges also describe significant, marked changes in elevation. Therefore, they are considered more primary than supplemental in the context of terrain features represented on military maps.
