The symbols of the U.S. Armed Forces include the Army logo, which is a white star with a golden border against a black background, and the seal and emblem of the Department of the Army. The Navy's official seal depicts an eagle carrying a ship's anchor. The Air Force symbol features stylized wings, a star, a sphere and three rhomboids at the base.
The major symbols of the five branches of the U.S. military vary in style and history. The Department of the Army's seal and emblem are similar to the Army seal that officers used to authenticate documents during the American Revolution. By contrast, the Air Force designated its current symbol in 2004.
The official seal of the Coast Guard features a pair of overlapping, golden anchors behind a white circle with a red, white and blue shield inside it. The official emblem of the Marine Corps, which is named the Eagle, Globe and Anchor, represents the worldwide presence and commitment of the Marines.
Recurrent motifs in U.S. military symbology include the gold star, which commonly represents sacrifice and loss of life in combat; the sphere or globe, which symbolizes the world; and the bald eagle, which is the country's national animal.
