Lieutenant Galloway was a male Human Starfleet officer who lived during the mid-23rd century. He served in the operations division aboard the USS Enterprise under Captain James T. Kirk during the mid-2260s.
As an officer of the operations division, Galloway was assigned as a security officer on the Enterprise, but also served briefly as one of the ship's transporter chiefs. (TOS: "The Galileo Seven") As a security officer, he referred to himself by the identification "Security 054". (TOS: "The City on the Edge of Forever")
His first assignment happened on stardate 2713.5, when the starship encountered Earth Two. He was a member of the landing party and was unknowingly exposed to a viral infection. He escorted First Officer Spock during an attack by the inhabitants. He also guarded a hospital lab where Doctor Leonard McCoy conducted his medical research. He was cured of the virus after McCoy discovered a vaccine. (TOS: "Miri")
On stardate 2821.5, he beamed in the survivors of the Galileo before the shuttlecraft incinerated around Taurus II. (TOS: "The Galileo Seven") He was a member of the Beta III landing party on stardate 3156.2 and was temporarily absorbed into the Body of Landru. (TOS: "The Return of the Archons")
He was imprisoned on Eminiar VII with the landing party on stardate 3192.1 and escaped with them while disguised as an Eminian guard. He assisted Spock in rescuing Ambassador Robert Fox from death in a disintegration station and guarded the Eminian High Council chamber as Kirk and Spock ended Eminiar's war with Vendikar. (TOS: "A Taste of Armageddon")
Later that year, he discovered an unconscious Lieutenant Kyle in the transporter room after a cordrazine-crazed McCoy beamed down to the surface of the time planet. He joined the landing party in search of the doctor. (TOS: "The City on the Edge of Forever") The following year, he guarded the quadrotriticale storage compartment aboard Deep Space Station K-7 and witnessed an avalanche of tribbles falling on Kirk. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")
He was killed on Omega IV by Captain Ronald Tracey in 2268. After exposure to the Omega IV virus and injured from an attack by a hostile tribe, he was vaporized by phaser fire at the hands of the USS Exeter captain. (TOS: "The Omega Glory")
Returning to duty in 2269, one of his later assignments was guarding the holding cell of Doctor Janice Lester, who was actually Kirk through a switch by a life-entity transfer machine. He witnessed Spock performing a mind meld and was the victim of a Vulcan nerve pinch when he resisted the first officer's attempts to convince him of the truth. (TOS: "Turnabout Intruder")
- Galloway: "Is he dead, Mister Spock?" (regarding McCoy)
- Spock: "Not yet."
- Galloway: "You're asking me to violate the captain's orders." (refusing to believe Lester was Kirk)
- Spock: "He is not the captain."
- Galloway: "You're as mad as she is. You're to leave here at once. I follow orders."
- Spock: "Certainly, Lieutenant. We all must do our duty."

The shooting script for The City on the Edge of Forever called him Davis.
Galloway was the second Star Trek recurring character, after Leslie, to return from the dead without explanation. Captain Tracey killed him with a phaser blast in "The Omega Glory". Ross appeared in "Day of the Dove" in the role of Lieutenant Johnson. He appeared again in "Turnabout Intruder" with the onscreen credit spelled as "Lt. Galoway".
In Star Trek II: Short Stories, Galloway was born and raised on Mars. He attended Starfleet Security Forces School for training as a security guard. After graduation, he served aboard Federation starships USS Leo, USS Jassan, USS Nelson and USS Thelonii before joining the Enterprise. By 2277, he was the security chief on the Enterprise and held the rank of sergeant.
James Blish's adaptations explained his demise and return. In the novelization of "The Omega Glory", Captain Tracey killed Lieutenant Raintree with his phaser, not Galloway. In the novelization of "Day of the Dove", the Beta XII-A entity restored an injured Galloway from his sword wounds, not Lieutenant Johnson.
