Which type of military flag identifies headquarters?

The type of military flag that identifies headquarters is distinguished flags. These flags serve as a visual representation of a unit's command structure and are typically used to designate the presence of a headquarters element. Distinguished flags often feature specific insignias or markings that denote the rank of the officer in command and the nature of the unit, thereby providing immediate recognition and clarity for personnel on the ground.

Understanding the role of distinguished flags within military operations highlights the importance of command presence and the chairing of authority. This helps ensure effective communication and organization, especially in operational settings where units need to identify their command elements quickly. In contrast, ensigns are primarily used to signify the national flag, colors refer to flags that symbolize a specific unit or division, and standards may indicate a particular unit's achievements or decorations, but none of these fulfill the specific function of identifying headquarters as distinguished flags do.
