Communications officer
The role of communications officer (also known as comm officer) was a specialized occupation held by crewmembers aboard Starfleet vessels, installations, and bases. Found across multiple divisions, the individuals holding the position were held responsible for managing all incoming and outgoing transmissions, whether they were visual, audio, or text communications.

During the 22nd and 23rd centuries, comm officers such as Ensign Hoshi Sato and Lieutenant Nyota Uhura held distinct positions on a starship's bridge. During the mid- to late 24th century, tactical and operations officers such as Lieutenant Commander Data and Lieutenant Worf doubled as communications officer. (; ; )

Surprised that Larr was able to pick up the English language quickly on his own, Doctor Phlox commented to Hoshi Sato in 2151, "Perhaps we've found an assistant comm officer." ()

In 2266, after Uhura expressed a frustration with hearing the word "frequency" that had nearly driven her to tears, Spock found himself unable to continue her line of conversation, given the illogic of a communications officer possessing such a sentiment. Uhura explained that she wanted him to talk with her about something else for a change. ()
