Terran Starfleet admirals were the highest grade of commissioned officers, known as flag officers. Personnel were awarded these ranks for rising through the line officer ranks of military service; the admiralty was based at Starfleet Command on Earth. They wore uniform jackets with red and silver division stripes at the shoulders over a white undershirt and necktie, and were the only officer grade that had sleeve stripe insignia in regular uniform wear. These dress jackets displayed only the Empire insignia on their right shoulder, with no opposite assignment patch. (ENT: "In a Mirror, Darkly, Part II")
The most senior flag rank, Starfleet fleet admirals in 2155 (like Fleet Admiral Gardner) wore a flag officer epaulet rank insignia of three gold chevrons with two smaller chevrons between them. The epaulets had admiral rank stripes, a thick silver band with a two separate silver stripes separated by two silver braids. (ENT: "In a Mirror, Darkly, Part II")

- In 2267, Starfleet captains (such as Capt. Kirk) wore thick gold braids at the shoulder of a metallic gold vest. (TOS: "Mirror, Mirror")
Terran Starfleet commanders were the second-most senior line officers. This rank was held by department heads and starship executive officers. Commander was inferior to captain, and superior to the lieutenant grades.

- In 2155, Starfleet lieutenant commanders (such as Lt. Cmdr. T'Pol) wore on their epaulets the insignia of two silver stripes, with single square pip pin in the center. (ENT: "In a Mirror, Darkly")
- In 2267, Starfleet lieutenant commanders (such as Cmdr. Scott) wore officer's tunics, with sleeve insignia of a solid and broken gold stripe. (TOS: "Mirror, Mirror")

- In 2267, Starfleet ensigns (such as Ens. Chekov) wore no rank insignia, but wore officer uniform tunics (with sash and, as they were early in their career, only a few decorations). (TOS: "Mirror, Mirror")
- In 2155, Starfleet enlisted personnel wore no officer decorations on their uniform. Crewman wore no epaulets, but non-commissioned officers (specialists and chiefs) wore epaulets with no officers rank insignia. (ENT: "In a Mirror, Darkly", "In a Mirror, Darkly, Part II")
- In 2267, enlisted personnel wore department color service jumpsuits or uniform tunics, with no decorations or officer sash. (TOS: "Mirror, Mirror")
