<P> Enlisted personnel wear a one - piece red jumpsuit (similar color to the officer uniform) with tan shoulders and upper chest and black undershirts . Enlisted trainees wore the same uniform, substituting a red undershirt for the black one . (Star Trek II). </P> <P> Uniforms similar to this style are shown in the "Next Generation" television series, although without the turtle - neck or belt (TNG: "Yesterday's Enterprise", "Dark Page", "Family, "Violations"). </P> <P> The Starfleet officers and crewmembers seen in The Next Generation wear a jumpsuit with a Starfleet communicator badge (or' combadge' as it was sometimes called) on the left chest and rank insignia on the right side of the collar . The black areas are seen on the shoulders and the pants and the uniforms's sleeves and abdominal area are colored to indicate the individual's branch, with red indicating command and helm; gold for engineering, security, and operations; and blue for science and medical (TNG: "Encounter at Farpoint"). The division colors for command and operations switched from those used in Enterprise and TOS . In early episodes, some crew members can be seen wearing a tunic version of the uniform with bare legs and boots, a homage to the women's uniforms in TOS . </P> <P> Beverly Crusher often wears a blue laboratory coat over her standard uniform, beginning in TNG: "The Naked Now ." The lab coat was primarily developed to hide the pregnancy of Gates McFadden . The blue tended to appear teal under certain lighting conditions in the later seasons and subsequent spinoffs . In some episodes of the later seasons, Jean - Luc Picard would sometimes wear a different uniform that consisted of a gray shirt with ribbed black shoulders and collar with a "bomber jacket" that was red overall with black ribbed shoulders, often worn open or very loosely fastened . The uniforms could be fitted with pouches for carrying tricorders and Type 2 phasers on the waist, and the early versions had a small pocket built in on the left side of the waist for carrying a smaller Type 1 phaser when appearing openly armed was not desired . The removable gear pouches were also incorporated into the uniforms used in DS9 and the TNG - era films from First Contact onward . </P>
