What form is used for cross-referencing?

The correct form used for cross-referencing is the DD Form 2861. This form is specifically designed to link records and provide references between different documents, thereby ensuring accurate tracking and organization of data across various systems. In the context of records management, effective cross-referencing is crucial as it enhances accessibility and aids in the retrieval of related information, which supports operational efficiency and compliance with regulations.

Other forms mentioned in the choices serve different purposes related to military records or administrative matters but do not focus on cross-referencing. For instance, the AF Form 1234 is utilized for a different aspect of Air Force record-keeping, while the SF Form 5678 and DA Form 9012 also pertain to distinct processes and reporting formats, lacking the dedicated function of cross-referencing documents that is essential in a comprehensive records management program.
