Official battle color of the U.S. Marine Corps

A centered Eagle, Globe, and Anchor on a scarlet background, with a streaming banner underneath bearing the words "UNITED STATES MARINE CORPS" in scarlet lettering.

The official flag is scarlet with the Corps emblem in gray and gold. It was adopted on 18 January 1939, although Marine Corps Order 4 had established scarlet and gold as the official colors of the Corps as early as 1925. The indoor/parade version is bordered by a gold fringe while the outdoor version is plain.
