Sal (portrayed by Joe Maruzzo) was a minor supporting character in Season 4 of Star Trek: Enterprise. Appearing in the episode "Storm Front, Part 2", he was a gangster and loan shark from New York in 1944. In an alternate timeline, Nazi Germany had invaded the United States and occupied Manhattan. Sal and his partner Carmine worked with Alicia Travers as part of the resistance movement against the occupation.
Sal led a resistance cell in attacking a Nazi convoy and rescuing Captain Jonathan Archer, who had been transported to this time period by a temporal agent named Daniels, from Nazi custody.
A few days later, he helped Archer interrogate a Na'kuhl named Ghrath for information, and ultimately shot Ghrath to death despite objections from Archer. During an encounter with the German occupiers later that night, Sal was shot in the back by a Nazi soldier armed with an MP40 submachine gun while attempting to flee from them.
