What is represented by brown on a military map?

Brown is used to represent contour lines and elevation on a military map. This color coding is crucial as it provides essential information about the terrain's elevation changes and topographical features. Contour lines connect points of equal elevation, allowing map readers to visualize the landscape's shape and gradient. Understanding these features is vital for various military operations, such as planning movements and understanding the strategic advantages of the terrain.

The other options represent different features on military maps: vegetation is typically shown in green, water bodies are indicated in blue, and major roads might be depicted in black or red, depending on the map's specific symbology. Recognizing these color codes helps users interpret maps accurately and efficiently in various scenarios.
