In military symbols, what color represents friendly forces on a map overlay?

In military symbology, blue is the designated color for representing friendly forces on a map overlay. This convention is integral to ensuring clear communication and understanding during operations. By using blue for friendly units, it helps to differentiate them from enemy forces, which are typically represented in red. This color-coding system promotes situational awareness, allowing commanders and soldiers to quickly identify the status of different elements on the battlefield, reducing the risk of fratricide and enhancing coordination among units. The use of consistent colors is crucial for effective planning and execution of military operations.
