Thanks for clearing it up.
Actually, he started at USMC HQ, which is a part of the Pentagon (adjacent to it) and completely separate from "8th and I."
He was then transferred to US CENTCOM in Pensacola, FL. While stationed there he did a six-month tour in the Middle East -- Qatar, Bahrain, and a handful of other countries. He did do classified work dealing with both Iraq and Afghanistan, but nothing in the line of fire.
He now works as a civilian contractor in Intelligence at Bolling AFB in D.C., while attending the University of Maryland at night. He intends to go into the FBI upon graduation.
