Which MOS refers to positions that officers are officially authorized to occupy?

The term that refers to positions that officers are officially authorized to occupy is known as the Duty MOS. This designation is used in the military to clearly identify the specific role an officer is assigned to within their respective branch. The Duty MOS reflects the current job responsibility that an officer is managing, which is important for organizational clarity and operational readiness.

This categorization allows the military to effectively allocate personnel to roles that match their training and expertise, ensuring that units are staffed appropriately with qualified individuals in their specific duties. The Duty MOS is recorded in official military records and plays a significant role in career progression, promotions, and potential assignments.

Other types of MOS, such as Primary and Additional MOS, do not hold the same authoritative weight in determining the official positions an officer is authorized to occupy.
