Pentagon (Tiberium)

The Pentagon is the headquarters of the United States Department of Defense and a vital element of the GDI defence system for the United States Eastern Seaboard, located at 48 N. Rotary Road, Arlington, Virginia 22211. Its mailing address is "Washington, DC 20301." As a symbol of the US military, "the Pentagon" is often used metonymically to refer to the Department of Defense rather than the building itself.

Built by Philadelphia contractor John McShain, the building was dedicated on January 15, 1943. It is the highest-capacity office building in the world and one of the world's largest buildings in terms of floor area. It houses approximately 23,000 military and civilian employees and about 3,000 non-defense support personnel. It has five sides, five floors above ground (plus two basement levels), and five ring corridors per floor with a total of 17.5 miles (28 km) of corridors.

The Pentagon came under heavy attack from Nod forces shortly after Philadelphia's destruction. Nod Militia managed to destroy the power supply to it's defences, rendering it almost completely defenceless. Thanks to te timely intervention of a resourceful GDI commander, the building was defended, with help from APC platoons and Grenadier squads that also arrived in the nick of time.
