Which color is used to indicate boundaries on a military map?

The color black is used to indicate boundaries on a military map, as it is a conventional color for representing man-made features and boundaries such as roads, railways, and political borders. In military mapping, each color has a specific purpose and conveys different types of information. Black typically features prominently in the representation of linear features and structures, making it an appropriate choice for designating boundaries, whether they are related to administrative, territorial, or jurisdictional lines.

Understanding the use of colors on maps is essential for effective navigation and communication in military operations, as quick recognition of features, including boundaries, can be critical in the field.
