George S. Hammond was a General in the United States of America most notable for his command of the SGC. Hammond was on the verge of retiring from this command when the Goa'uld System Lord Apophis launched an attack on Earth in 1997. In the aftermath, Hammond became the Commander-in-Chief of the newly reopened Stargate Command, serving in the role for the first seven years of its existence before he was relieved of command in 2004.
