Which document reflects authorized positions within a unit?

The Unit Manpower Document (UMD) is the correct answer because it specifically outlines the authorized positions within a unit. It serves as an official record that details the staffing structure, including job titles, grades, and the number of personnel assigned to each position. This document plays a critical role in resource allocation, ensuring that the unit is properly staffed to meet its mission requirements.

The UMD is vital for management as it provides a clear overview of how many personnel are authorized in different roles and allows for strategic planning to meet unit needs. This information is essential for effective human resource management, budgeting, and operational planning.

Other documents, while relevant to the organizational structure and manpower, do not serve the same specific function as the UMD. For instance, the Manpower Authorization Document outlines the overall manpower requirements but does not detail individual unit positions. The Unit Mission Document describes the unit's purpose and goals but does not enumerate specific authorized positions. The Personnel Management Report reflects various aspects of personnel data but lacks the focused scope of listing authorized positions within a unit.
