From The Stargate Omnipedia


A general in the United States Air Force, Kerrigan served in a command position at the Air Force Academy. He is personally acquainted with Samantha Carter, apparently since her days as a student there.

Kerrigan did not initially have clearance to know about the top-secret Stargate program. But when the S.G.C. began recruiting graduating cadets for service, Kerrigan was brought into the loop. He works with Stargate Command for annual training scenarios, designed to test young cadets' ability to "think outside the box" -- testing their qualifications for service at the S.G.C.
