The Army National Guard's flag history is rooted in the colonial militias that formed in 1636. While the history is long and complex, the current official flag is a more recent creation that has been updated to reflect its modern role. The Army National Guard officially got its name in 1916 with the National Defense Act. The service became an official component of the Army in 1933. Made of 100% Heavyweight SolarMax ® 200 Denier Nylon, it features strong duck heading and two large brass grommets. Durable against heavy weather and beautiful to look at.
