Which device denotes a second consecutive award for the Army and Air Force?

The Oak Leaf Cluster is indeed the correct answer because it is awarded to denote a subsequent award of certain military decorations for the Army and Air Force. Specifically, the Oak Leaf Cluster is used to signify additional awards after the first, allowing service members to indicate they have received the same honor more than once.

In this context, if a service member receives a certain medal and then earns it again, they receive an Oak Leaf Cluster to attach to the original medal, effectively representing that they have achieved the award a second time. This system allows for a clear and recognizable indication of multiple awards without requiring a completely new medal each time.

Other options, such as the Gold Star and Silver Star, represent different honors or ideas within military awards. The Gold Star typically represents a service member who has died in service, while the Silver Star is a decoration awarded for gallantry in action. The Bronze Oak Leaf is not a recognized military award. Each of these serves distinct purposes and does not pertain specifically to the designation of repeated awards like the Oak Leaf Cluster does.
