What action must take place if a Soldier's duty status changes?

When a Soldier's duty status changes, it is essential for an update to be made in the personnel system. This action ensures that the soldier's status is accurately reflected and maintained within official records, allowing for proper tracking of personnel and their assignments. The personnel system captures essential information such as active duty status, leaves taken, and any other relevant changes that may affect the Soldier’s career and obligations. Keeping the system updated supports effective management of troops and ensures that all levels of command have access to the most current information, which is crucial for planning and operational readiness.

Other actions like immediate reporting to command, notification to family members, or recording in a personal file can be pertinent in certain contexts, but they do not fulfill the requirement to officially document the change within the military's personnel management system. It is the update in the personnel system that provides the foundational record-keeping necessary for all subsequent actions and decisions related to the Soldier's duty status.
