Final answer:
For five or more awards, a wreathed "E" is authorized to be centered on the ribbon bar, which signifies multiple awards of a military decoration.
Step-by-step explanation:
For five or more awards, one wreathed "E" centered on the ribbon bar is authorized. In the context of military awards, a ribbon bar is a small ribbon, mounted on a bar, that denotes the award of a medal or decoration. When multiple awards of the same decoration are authorized, additional awards are often represented by devices attached to the ribbon bar. For instance, in the United States military, the Navy "E" Ribbon denotes permanent duty on ships or in squadrons that have won the battle efficiency competition. If a service member earns the ribbon five or more times, a silver wreath is authorized to be worn on the ribbon bar to indicate the multiple awards.
