Crewman (also known as ables'man or able crewman) is an enlisted naval rate, a type of military rank used by the service organizations of different cultures. This title is the lowest enlisted rank, subordinate to a petty officer. In comparison to infantry ranking systems, this rank is approximately equivalent to the grade of private. In Klingonese, this rank is referred to as bekk.

In Starfleet, this rank is awarded upon completion of a training course, where recruits are given basic instruction in manning a starship or filling another role in the fleet.

Some rank systems use different grades of crewman, such as "crewman first class", "crewman second class", etc.

crewman first class

• In 2367, Simon Tarses identified himself as a crewman, first class. (TNG: "The Drumhead")

crewman second class

• In 2151, Commander Trip Tucker threatened to demote Lieutenant Malcolm Reed to the rank of crewman, second class. (ENT: "Shuttlepod One")

crewman third class

• Although this rank has never been mentioned, three grades of crewman insignia were in use in the Earth Starfleet. This lowest grade was never mentioned by name, but the insignia was worn by Daniels, Cunningham, and others.

Background

Although Star Trek has often been ambivalent about enlisted ranks and insignia, there have been mentions of the term "crewman" since TOS:"The Man Trap, although it is continuously impossible to tell who this rank was bestowed upon, since both crewman and ensigns (as well as chief petty officers) had no visible rank insignia. In the Star Trek Movies era, costume designers created insignia for chiefs and pettys 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 Trek. By TNG"The Drumhead," it was established in dialogue that Simon Tarses was an enlisted crewman who had not gone to the Academy, he had a blank collar. This lack of rank insignia for crewmen and noncoms was used throughout DS9 and VOY, although chief petty officers were assigned different insignia.

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