Which roster identifies personnel ineligible for promotion under WAPS?

The correct answer is the Unit Airman Ineligible for Promotion List. This roster specifically identifies personnel who are not eligible for promotion under the Weighted Airman Promotion System (WAPS). It consolidates information about airmen who may have disqualifying factors such as failure to fulfill certain requirements or not meeting specific criteria necessary for promotion consideration.

In contrast, the other options serve different purposes. The Airman Base List contains airmen who are eligible for promotion but does not specifically highlight those who are ineligible. The Promotion Eligibility Roster is used to track those who meet the conditions for promotion; however, it does not indicate any ineligibility. The Enlisted Record of Assignments documents an individual's duty assignments and service history, which may contribute to promotion eligibility but does not directly identify ineligible personnel. Understanding this distinction clarifies why the Unit Airman Ineligible for Promotion List is the appropriate choice for identifying personnel who cannot be promoted.
