Who is responsible for slotting soldiers into primary MOS or career progression MOS?

The responsibility of slotting soldiers into their primary Military Occupational Specialty (MOS) or career progression MOS primarily rests with the Commander. Commanders have the ultimate responsibility for the personnel within their units, which includes overseeing the assignment and development of soldiers according to their skills, qualifications, and the needs of the Army. This role involves not only making decisions based on the current operational requirements but also considering soldiers' career development and future assignments.

While other personnel, such as the Personnel Officer, may provide input and manage certain administrative aspects of personnel assignment, the Commander retains the authority and responsibility to make final decisions regarding slotting and career progression. This includes ensuring that soldiers are placed in positions that capitalize on their strengths while also fulfilling the unit's requirements. As such, the Commander's leadership and understanding of both immediate and long-term goals of personnel management are critical in these processes.
