Members must have been permanently assigned or attached by official orders to the agency for 30 or more days during the designated award period. Service members individually assigned or attached (including temporary duty or temporary additional duty) status is determined by official orders that specify the agency as the duty unit. Some military services allow the “temporary-wear” of past unit citations when assigned to the organization. The Joint Meritorious Unit Award is an exception to this rule and is not authorized for temporary wear.
