The Pentagon is the headquarters and command epicenter for the Department of Defense (DoD) and the four military service components. Situated in the Pentagon is the Office of the Secretary of Defense, the Joint Chiefs of Staff, and the headquarters for the U.S. Air Force, U.S. Army, U.S. Navy, and the U.S. Marine Corps. These organizations oversee a combined annual DoD budget of over $583 billion and three million employees (both military and federal civilian personnel). DoD operates and sustains more than 200 major military installations and over 5,000 other defense sites worldwide.   

The Pentagon itself is one of the world's largest office buildings.  It's floor space covers over 29 acres (6,636,360 square feet). The Pentagon has 5 floors and more than 17.5 miles of hallways and corridors. Working at the Pentagon are approximately 23,000 personnel. This includes both military and federal civil service personnel.

To sustain the senior leadership (and their respective staffs) of DoD and the four military service headquarters, a vast network of defense contracting offices and procurement teams work year round issuing new contract solicitations and managing active government contracts.
