Billets And Skill Growth
Entry-level Marines focus on core tasks, equipment, field discipline, and reliable execution.
NCOs supervise small teams, enforce standards, plan rehearsals, and train junior Marines.
SNCOs and officers manage readiness, risk, training plans, inspections, reporting, and integration with adjacent staff sections.
Instructor and staff billets preserve standards, document lessons learned, and build repeatable training for the next rotation.
Chain of Command Matching Logic
Chain of command records can list a current MOS, prior record MOS, ADMOS, or specialty track. This page shows a member as a Current MOS when the MOS is the member’s active specialty and as Recorded Profile MOS / ADMOS when it appears in the member history.
