General John P. Jumper is the Chief of Staff of the US Air Force, and during the Hayes administration he was among the chiefs of staff and advisors in the Oval Office who counseled the President during Anubis's attack on Earth. He reported that space-based radar had detected three motherships from Anubis's fleet emerging from hyperspace, and he ordered the launch of the Prometheus, which engaged Anubis's fleet in battle over Antarctica and saved Earth.
