Which formal document is necessary to finalize adjustments related to duty assignments?

The correct answer is AF Form 2096, which is specifically utilized for documenting personnel actions, including duty assignments. This form serves as a formal mechanism to reflect changes such as duty assignments, promotions, and other career-related adjustments within the Air Force personnel system. When making changes to an individual's duty status, submitting an AF Form 2096 ensures that the new assignment is officially recorded, facilitating proper tracking and administration of personnel actions.

While the other forms may have significant roles in personnel management, they do not directly pertain to finalizing duty assignments in the same way AF Form 2096 does. For instance, AF Form 100 is typically used for requests involving retraining, and AF Form 214 is used primarily for documenting the separation of personnel from military service. AF Form 402 is related to requests for awards and decorations, serving a different purpose within personnel management. Thus, AF Form 2096 holds the crucial function of capturing and formalizing changes specifically related to duty assignments.
