What document must a complainant receive written feedback on within 14 calendar days?

The correct answer emphasizes that the complainant must receive written feedback on specific sections of the DA Form 7279-R, which includes Parts II and III. This form is integral to the Army's process for handling complaints, as it details the essential elements of the complaint and the subsequent actions that must be taken.

Receiving feedback within a stipulated timeframe, such as 14 calendar days, is crucial in maintaining transparency and accountability in the complaint process. This timeline ensures that concerns are addressed promptly, allowing the complainant to feel heard and providing necessary updates regarding the outcome of their complaint. The utilization of Parts II and III of the form allows for a comprehensive review of the complaint, ensuring all pertinent aspects are consistently communicated to the complainant.

In contrast, the other options pertain to different sections or forms that may not align with the specific requirements for feedback on complaints. For example, Parts I and II of the DA Form 7279-R or other forms may not encapsulate the entire process or may focus on different aspects unrelated to the requirement for feedback, thereby not fulfilling the needs of the complainant in the way specified in the question.
