Two incarnations of this team have been completely destroyed. Apophis captured SG-11 in order to study their knowledge and behavior so he could prepare his forces to infiltrate Earth. A later incarnation of the team was wiped out on P3X-888. Some were killed by Unas while the team leader, Hawkins, was taken over by a Goa'uld and later killed by Teal'c.
