How is a streamer for service in Afghanistan denoted?

A streamer for service in Afghanistan is denoted by the name "Afghanistan." This is an official recognition that reflects the involvement of a unit in service during the operations in that specific country. Each streamer serves as a visual distinction that represents the history and achievements of the unit, and naming the country is a straightforward way to identify the theater of operations.

While other options may pertain to different aspects of military recognition, such as specific dates, years, or types of campaigns, they do not specifically denote service in Afghanistan in the same clear and direct manner as using the name of the country. The inclusion of the name "Afghanistan" serves to commemorate and acknowledge the distinct nature of service rendered there. This clarity helps to maintain historical accuracy and pride in the service performed during that period.
