Enlisted personnel (also called rates, crew, or men) are people in Earth Starfleet or Federation Starfleet vessel who are not commissioned officers—meaning they have not taken and passed the full four-year Starfleet Academy course, only a shorter basic training course.
Enlisted personnel have a hierarchy of rates (rather than ranks) with three main levels:
- Crewmen (corresponding to army private and corporal grades);
- Petty officer (corresponding to an army sergeant); and
- Chief petty officer (corresponding to army staff sergeant and higher grades).
- These may be further subdivided, possibly in to different subdivisions at different points in history, but the subdivisions are not established in canon, merely inferred from analogy with United States Navy practice. See the table below, under History
In 23rd and 24th-century Starfleet, the distinction between officers and enlisted is less to do with social class and more to do with whether the individual wants to advance their career through leadership and management, or through concentrating on technical or administrative skills. Unambitious beings may remain in the crewman level for their entire career. Technical specialists may become respected for their experience and knowledge without needing to be promoted to commissioned rank. A chief petty officer, while technically subordinate to any officer, will act as advisor to junior officers and a peer of commissioned officers.
Enlisted personnel may also progress from administration to command and become commissioned officers (referred to as being "prior enlisted" or a "mustang"). As an example, Janice Rand served on the USS Enterprise as a petty officer (TOS) and chief petty officer (Star Trek: The Motion Picture), and later on the USS Excelsior as lieutenant junior grade. (Star Trek VI: The Undiscovered Country)
Officers generally address crewmen by surname (or their culture's closest equivalent), or as "crewman". Most Starfleet vessels follow the United States Navy practise of addressing crew as "crewman" regardless of sex. (TOS, TNG, etc.)
"Crewman" is a generic term and specific terms may be used for people serving in different departments, such as "mechanic" and "steward". (TOSS)
- The producers of the series did not like the term "petty officer" and avoided using it.
Crewmen at chief petty officer or above are addressed as "chief" both by officers and by lower-rated crew, "senior chief" when at the rank of senior chief petty officer and "master chief" at master chief petty officer.
Pre-industrial navies of Earth had a sharp division between officers and men corresponding to the division between gentlemen and commoners in wider society: officers gave orders and the men did hard manual labor. The classes of non-commissioned officers and warrant officers evolved to bridge the gap between officers who had no knowledge of sea-faring, and men who had experience and skills but could not be commissioned officers because they were not of the required social class.
By the twentieth century the division between officers and men still existed, but corresponded to the difference between (university or college) education versus vocational training and on-the-job experience. In many countries, officers invariably have a university degree (the Royal Navy of Britain and the United States Navy being exceptions). As the technology of warfare increased in sophistication, this division became increasingly blurred, and by the end of the century, navies where re-evaluating the ways skills and knowledge were to be related to positions in the hierarchy.

To make things more interesting, Royal Marines with rank warrant officer have an appointment in addition to rank, and are addressed according to appointment (such as company sergeant major, regimental quartermaster sergeant, et al.) rather than rank. Similarly, crewmen and privates are often addressed according to specialization (gunner, sapper, operator-mechanic, etc.) rather than the generic rank.
In the 23rd century, there were no differences in insignia between different rates.
- Scripts of TOS, and some contemporary supporting materials, treat ensigns and crewmen as interchangeable terms. This and the lack of insignia suggests a much-simplified hierarchy of rates.
- For TNG, Gene Roddenberry envisaged starships operated by officers only, which makes sense if you think in twentieth-century terms where only officers have the education required to operate a space vessel. In later series crewmen were retconned back in to canon, with Chief petty officer Miles O'Brien being a main character.
In the early 2270s, petty officers and chiefs have a unique symbol on their shoulder strap.
|Chief petty officer|
- There is no screen evidence for further subdivisions of the rates, though designs for these insignia have been conjectured.
From the 2350s, rank was indicated by pips work on the right collar. Enlisted personnel had no insignia, except for chiefs, indicated by a single hollow pip. (TNG)
From 2372, a lozenge on the collar distinguished different classes of petty officer and chief petty officer.
