What do brown colors on a military map signify?

In military map reading, brown colors are used specifically to represent terrain and relief features. This includes changes in elevation, such as hills and valleys, which are crucial for understanding the geography of the area. Elevation is often indicated through contour lines, which are typically brown; these lines help identify the steepness of the terrain and the lay of the land, which can be vital for planning movements and assessing tactical advantages.

Understanding these brown markings is essential for operations in varied terrains, as it can influence decisions regarding troop movements, logistics, and overall mission planning. Although other colors on the map represent different elements, brown is distinctly associated with the depiction of the earth's surface features, making it instrumental in navigation and tactical operations.
