Private Owen Salazar-Tucker was a MACO soldier during the Earth-Romulan War and the son of Albert Tucker and Miguel Salazar.

In 2156, Owen's desire to join the MACOs was a matter of argument between him and his parents. Owen eventually left home to join the MACOs.

In 2157, Owen was stationed aboard the Enterprise when he landed with fellow MACOs on Galorndon Core. During the ensuing firefight, Owen rescued Sergeant Selma Guitierrez after she was injured and carried her to the waiting shuttlepod. (ENT episode: "To Brave the Storm")
