Lieutenant Grogan, an Air Force Academy graduate, participated with Elliot, Hailey, and Satterfield in the SGC training scenarios under O'Neill. Despite a propensity for becoming a target, Grogan passed the training program and was assigned to SG-9 under Major Benton. He participated in the diplomatic mission to reestablish relations with Latona and to negotiate access to the Sentinel, but he was the only member of his team to survive the attack on Latona by Svarog's forces.
