Penhall was a member of the SG-2 Marine unit.



He participated in the liberation of the Jaffa penal colony on Erebus. Colonel Jack O'Neill switched his standard FN P90 Personal Defense Weapon with Penhall's HK SL8 sniper rifle which he used to eliminate the Jaffa in the camp. He is a proficient marksman, and was used to lay down cover fire for the rebel Jaffa with O'Neill's P90. (SG1: "Orpheus")

When Dr. Daniel Jackson, Teal'c, and Chaka went to negotiate with the Unas on P3X-403, Colonel Martin Edwards sent him and Hanson to back them up. (SG1: "Enemy Mine")

Notes Edit

  • Penhall's name is mentioned in Twin Destinies as well. While the Destiny crew is salvaging parts from the second Destiny, Brody and Volker are retrieving parts from the bridge when Volker departs and informs an SGC soldier apparently named Penhall that he's going with Volker to their next stop. Whether it's the same character, or this character is related to the Penhall from SG-1, or this is a completely different character with the same name homage is unclear as the character in this scene was poorly lit and hard to identify. (SGU: "Twin Destinies")

Behind the scenesEdit

  • The name Penhall may be a reference to Peter DeLuise's work on 21 Jump Street, where he played a character named Doug Penhall. And Penhall is always mentioned in connection to Hanson, which was Johnny Depp's character on 21 Jump Street.
