Which of the following is not an appurtenance for military awards?

In the context of military awards, an appurtenance refers to any additional item that is attached to or associated with a military decoration to signify specific achievements or qualifications. Clasps, device stars, and the Berlin Airlift Device are recognized forms of appurtenances that augment military awards by marking particular feats, campaign participation, or certain qualifications.

Clasps are additional pieces that can be added to medals to denote further achievement or service. Device stars serve a similar purpose, indicating multiple awards of the same decoration by adding stars to the ribbon of the medal. The Berlin Airlift Device specifically denotes participation in the Berlin Airlift, adding further distinction to those who served during that operation.

Patches, on the other hand, are not considered appurtenances for military awards. They are generally used to denote unit affiliation, skill qualifications, or other non-award related recognitions. While they may hold significant value within the military community, they do not alter or enhance a military award in the ways that clasps, device stars, and specific devices do. Therefore, patches are not classified under the term "appurtenance" in the context of military awards.
