The Trust Operative was a member of The Trust. He was unaware that the trust had been infiltrated by the Goa'uld. He was assigned by the Trust to spy on Major General Henry Landry and SG-1. He received a Sodan Invisibility device from his Principals to spy on them. In the beginning it went well until a few hunters heard something and thought it was the monster that was attacking everyone. He was hit by a bullet that went trough him.
When Lt. Colonel Cameron Mitchell went to check out what the sound was making he found him cloaked but he was betrayed because of his injury. Mitchell interrogated him but he didn't say a thing expect that he was going to die. At the time he was unaware that the Trust had been infiltrated by the Goa'uld. Some time later he was taken to an ambulance. (SG1: "Uninvited")
