When must the commander provide written feedback to a complainant?

The requirement for the commander to provide written feedback to a complainant not later than the 14th calendar day after receiving the complaint is grounded in the principles of accountability and transparency within military operations. This timeframe ensures that complaints are addressed promptly, fostering trust among personnel that their concerns are taken seriously.

Providing feedback within this period allows the commander to conduct a thorough review and take any necessary action while ensuring the complainant is kept informed, which is vital for morale and adherence to protocols. This timeline is designed to ensure that complaints are handled with due diligence while also emphasizing the importance of timely communication in maintaining an effective command structure.

The other options either suggest a timeframe that is too short, which may compromise the thoroughness of the investigation, or too long, which could lead to a perception of neglect and could undermine trust in the command's responsiveness to issues raised by personnel.
