This includes the corresponding uniforms worn in the mirror universe by the Terran Starfleet. (See: alternate reality.)

↑ 4.04.14.24.34.44.54.64.7Sleeve stripes were used with this style beginning in "The Corbomite Maneuver" and continued throughout all canon Star Trek: TOS-era productions. Ensigns and other supernumerary crew (referred to in dialogue as "crewmen" and sometimes, oddly, "lieutenant") lacked sleeve insignia. Stripes seen on screen include lieutenant junior grade ("The Naked Time" only); lieutenant (sometimes LTs lacked stripes, however); lieutenant commander (sometimes LCDRs wore CMDR stripes, however); commander; captain; commodore and vice admiral ("The Trouble With Tribbles" only).
