Through which entity must a UMD request be made?

A UMD (Unit Manpower Document) request must be made through the Force Support Squadron (FSS). The FSS is responsible for managing personnel and manpower requirements within the Air Force, including handling requests for manpower adjustments, resource allocation, and maintaining the integrity of the UMD. This entity ensures that all personnel-related requests align with organizational needs and support the mission effectively. The FSS serves as a liaison between the unit and higher commands regarding manpower issues, making it the correct channel for submitting UMD requests.

The other entities, while related to different areas of support or management within an organization, do not specifically handle UMD requests. For example, Human Resources typically focuses on personnel policies and benefits rather than manpower needs; Operations Support Groups manage operational activities but not manpower documentation; and Resource Management Offices deal with broader resource allocation rather than focusing specifically on manpower documentation.
