A rosette is a decorative looped ribbon or fabric bow, often used to adorn military medals and awards. It is typically attached to the medal's ribbon or suspension bar. The purpose of a rosette can vary depending on the country and the specific award it accompanies.

Here are a few common uses of rosettes in military awards:

Multiple Awards: In some military systems, when a recipient is entitled to receive the same award multiple times (for example, for repeated acts of bravery), additional awards are indicated by the attachment of rosettes to the ribbon of the original medal.

Campaign or Service Ribbons: In some cases, rosettes are used to indicate participation in specific campaigns or periods of service. Each rosette may represent a different campaign or period.

Level or Class of Award: In some military orders or decorations, rosettes can denote a particular class or level of the award. For example, a higher class of a particular decoration may be indicated by the presence of a rosette.

Commendation or Mention in Dispatches: In some systems, rosettes may be used to denote commendations or mentions in dispatches. These are awards for gallantry or meritorious service that may not carry a separate medal.

Aesthetic Decoration: In many cases, rosettes are used for purely aesthetic purposes, enhancing the appearance of the medal's ribbon.

It's important to note that the specific use and design of rosettes can vary significantly between different countries and their respective military traditions. Therefore, the exact meaning and usage of rosettes will depend on the specific military system or order in question.
