Which of the following are supplementary terrain features found on a military map?

Supplementary terrain features on a military map help enhance the understanding of the main topographical elements by providing additional context for navigation and tactical planning. Cut and fill refers to terrain features that are created by excavation and embankment.

A "cut" is formed when material is removed from a hillside or surface area to create a path or road, often resulting in a steep slope. Conversely, a "fill" is the opposite process, involving the placement of material to elevate the ground, creating a raised surface or embankment. Together, cut and fill features are significant in understanding how the terrain has been modified for roadways, airfields, or other military constructions.

In contrast, other options provide descriptions of main terrain features. Draws and cliffs describe distinctive shapes in the landscape, hills and spurs relate to elevation points, while valleys and basins refer to low-lying areas. While all these terms are relevant to terrain assessment, the focus of the question falls specifically on supplementary features, making cut and fill the accurate choice.
