Final answer:
To update the UIC hierarchy, one must access the relevant military or organizational database with proper authorization and follow the correct protocols to add, edit, or deactivate UICs as needed.
Step-by-step explanation:
The UIC (Unit Identification Code) hierarchy is typically updated in a military or organizational database that is used for managing various units within an organization. If you are looking to update the UIC hierarchy, it is usually done through the specific software or database system that your organization uses for this purpose. For instance, in the U.S. military, the UIC hierarchy might be updated through the Defense Property Accountability System (DPAS) or other relevant logistics or administrative systems.
Updating the UIC hierarchy often requires proper authorization and access to ensure data integrity and security. If you are authorized to make updates, you would usually log into the system, navigate to the section where UICs are managed, and perform the necessary actions, such as adding a new UIC, deactivating an old one, or editing the information associated with a UIC.
Remember, it is always important to follow your organization's protocols when making changes to the UIC hierarchy. If you are unsure about how to proceed, consult with your supervisor or the system administrator for guidance.
