Wraith warrior

From SGCommand

Wraith warriors are the military grouping of the Wraith. They are predominantly male. They wear masks that appear to be made of bone, completely covering their faces, so much that even their eyes cannot be seen. Their armor also possesses a self-destruct device that has a ten second countdown. In addition to stunners, some have been seen carrying grenades. They are described as being unimaginative, and with rigid thought patterns. (ATL: "Rising", "Suspicion", "The Defiant One", "Misbegotten")
