Sgt. Sylvester Siler

Sylvester "Sly" Siler is a Master Sergeant in the United States Air Force and technical expert at Stargate Command.

He was responsible for overseeing the repairs on the Stargate when it overloaded and sent Captain Samantha Carter and Colonel Jack O'Neill to the Beta Gate in Antarctica. (SG1: "Solitudes")

When SG-1 beamed the Alpha Gate to the Biliskner, he supervised the installation of the Beta Gate at Stargate Command. He then traveled to the Naval base where the Blackbird was docked and helped to coordinate the destruction of the Replicators. (SG1: "Small Victories")

Siler sometimes helps Samantha Carter work on her motorcycle. He has a set of pajamas given to him by Jack O'Neill. In 2004, O'Neill said that his collection of The Simpsons video cassettes will go to Siler. One year later, he learned that he was in Siler's will. (SG1: "The Curse", "Lost City, Part 2", "Reckoning, Part 2")
