Senior Chief Petty Officer (Abbreviated to SCPO and referred to as Senior Chief or Chief) is a senior non-commissioned rank used by Starfleet. Senior Chief Petty Officers serve in leadership roles in their respective departments (Engineer's Mate or Master-at-Arms, for example), or -in some cases- as the Chief of the Boat, and may also serve in any officer post - in rare cases even department head. They generally have many years of service and a wealth of experience in their selected field.
Chief Petty Officers serve a dual role as both technical experts and as leaders, with the emphasis being more on leadership as they progress through the CPO ranks. A recognized, collateral duty for all Chiefs is the training of Junior Officers.
