SHIELD
Dark blue and gold are the colors traditionally used by the Navy. The pentagon shaped shield, representing the Department of Defense, has a border or faade the color of limestone buff except the red section of the Southwest wall. The red section symbolizes the area of the Pentagon where American Airlines Flight 77, commandeered by suicide-terrorists, was targeted and crashed into the building on September 11, 2001. The laurel wreath is symbolic of honor and high achievement, and commemorates the heroism of the first responders to ground zero at the Pentagon. The trident, representing sea prowess, underscores USS Arlington's missions to support the embarkation, transportation, and deployment of the Marine Corps landing force to conduct primary amphibious warfare missions. The Pentagon's location in Arlington County is highlighted by the Arlington House adapted from the Arlington County seal.
CREST
The thirteen stars between the rays are from the Department of Defense seal. The two benches with the trees represent two of the 184 illuminated benches of the Pentagon Memorial, a permanent outdoor memorial to the lives taken in the Pentagon and on the American Airlines Flight 77. The bald eagle, embodiment of strength, vigilance and resolve, is long associated with the United States of America and our Armed Forces. It is soaring with above bowing its head in respect for the fallen. The eagle's wings echo the shape of the Memorial Benches.
SUPPORTERS
