Crewman Angelo Tassoni served as a security officer on the USS Voyager, starting in 2376. He was also a skilled pilot. (ST:CCG: "The Borg")
Tassoni had initially been assigned to the USS Equinox under Captain Rudolph Ransom. In 2371, the Equinox and all hands were transported to the Delta Quadrant by the mysterious Caretaker (Nacene). The Equinox crew abandoned many Starfleet principles in a desperate attempt to return home with limited resources. Tassoni was one of five Equinox survivors brought aboard the Voyager by Captain Kathryn Janeway. Along with his fellow survivors, Tassoni was reduced in rank to crewman and placed under strict supervision. (VOY episode: "Equinox")
