In Starfleet, an enlisted crewperson is one who has not completed the four-year Starfleet Academy course. Enlisted crewmen receive basic training, along with any specific courses required for their position at the Starfleet Technical Services Academy on Mars, before being posted. (TNG: "The Drumhead", "Eye of the Beholder"; DS9: "Shadowplay", "Starship Down")

Other force structures, such as the Klingon Defense Force and the Bajoran Militia, have enlisted men in their ranks,(citation needededit) but it is unclear as to how they differ from their standard officer ranks.

As with commissioned officers, there is a rank structure among enlisted crew.(citation needededit) The term "non-commissioned officer" refers specifically to any enlisted personnel given authority over other personnel.(citation needededit) In Starfleet, this refers to any petty officer up to master chief.(citation needededit)

All commissioned officer ranks, from ensign upward, outrank all enlisted officers in the chain of command.(citation needededit) However, in certain cases, non-commissioned officers can exercise authority over commissioned officers.(citation needededit) Additionally, chief petty officers, such as Miles O'Brien, wield influence far beyond their place in the rank structure due to their extensive experience and skill and act as mentors to junior enlisted and commissioned officers.(citation needededit)

Enlisted personnel may be promoted to receive a commission, but must pass necessary examinations and/or attend the Academy.(citation needededit)

Rank structureEdit

Naval ranksEdit

The Star Trek Encyclopedia refers to these ranks with the non-canonical designation "ables'man". Some modern systems refer to crewman 2nd and 3rd class as "apprentice" and "recruit", respectively.

Groundside ranksEdit

This chart shows only general equivalencies based on the ranks used by many governments on Earth, as well as the rest of the galaxy.


Gene Roddenberry initially envisioned a Starfleet entirely composed of officers during the creation of The Original Series, "Although the Enterprise is a military vessel, its organization is only semimilitary. The "enlisted men" category does not exist. Star Trek goes on the assumption thta every man and woman aboard the USS Enterprise is the equivalent of a qualified astronaut, therefore an officer." (The Making of Star Trek, p. 209)


Robert Fletcher's original costume notes

In the Star Trek movies, costume designers created insignia for chiefs and petty officers and even crewmen. In particular, Robert Fletcher's Star Trek II: The Wrath of Khan uniforms had an entire series of enlisted rank insignia. Some of these were reproduced (albeit incorrectly) in the Star Trek Encyclopedia. This is the origin of the "ables'man" term which has not been used elsewhere in Star Trek.

Fletcher's original costume notes actually referred to the rank of crewman as "able seaman", a term which has been used nowhere else in Star Trek with most sources referring to the pin designed by Fletcher simply as "crewman".

The Star Trek Encyclopedia had the TNG-era enlisted insignia labeled as "warrant officers", which contradicts several canon mentions.
