Galloway is a security officer aboard the Enterprise, played by David L. Ross. He beams down with landing parties in Miri, A Taste of Armageddon and The City on the Edge of Forever, among other episodes.
On Eminiar VII in A Taste of Armageddon he helps Kirk's party resist the planet's government, at one point passing himself off as a local guard.
In The Omega Glory he accompanies Kirk, Spock and McCoy to Omega IV, where Captain Ronald Tracey of the USS Exeter kills him with a phaser. Ross nevertheless appears again in the final episode, Turnabout Intruder, credited under almost the same name, as one of the guards watching Janice Lester.
