What does the color red-brown indicate on a military map?

The color red-brown on a military map is used to indicate non-surveyed areas. This color typically represents features that are not precisely measured or mapped, which distinguishes them from areas that have undergone detailed surveying and representation in more definitive colors. Understanding the color coding on maps is essential for interpreting the terrain and planning movements effectively, especially in contexts where accurate navigation and situational awareness are critical.

In contrast, boundaries are often represented by different color schemes established by military mapping standards, while man-made features are generally depicted in other colors. Water features have a specific color as well, typically blue. Therefore, recognizing that red-brown specifically denotes non-surveyed areas helps users quickly identify regions that may lack detailed information.
