Major Graham was the commanding officer of SG-14. Under his command were Captain Blasdale, Lieutenant Astor, and Sergeant Louis. During a joint mission with SG-15 to the Lasarians on P6Y-325, the teams were attacked by Jaffa, and Major Graham and Lieutenant Astor were captured and programmed as zatarcs using Goa'uld mind control technology. Graham was programmed to assassinate Supreme High Councilor Per'sus of the Tok'ra. During negotiations on Vorash for an Earth-Tok'ra alliance, Graham's assassination attempt failed, and he took his own life as part of his programming.
