Security Officer
This First Sergeant/Senior Master Sergeant was a member of SGC security forces. He was monitoring the palm scanner at the SGC entrance when the Ashrak pursuing Jolinar of Malksur infiltrated the base. The palm-scan equipment worked properly, but the Ashrak was able to use his miniature hand-device to cloud sergeant's mind.

The show credits list the role simply as 'Security Officer'.
