Which color indicates enemy forces on map overlays?

The color red is universally recognized in military operations and map overlays to signify enemy forces. This convention allows for clear and immediate identification of potential threats on tactical maps. Using red for enemy forces aids in maintaining situational awareness among troops and ensures that all soldiers can quickly recognize enemy positions without confusion.

In contrast, blue typically represents friendly or allied forces, black is often reserved for boundaries or object outlines, and yellow may be used for other purposes, such as hazards or points of interest, depending on the context and map legend. Thus, red is integral to effective communication in a battlefield scenario, highlighting its importance in operational planning and execution.
