The museum is free to the public, but timed-entry tickets are required.

The National Museum of the United States Army, located on the publicly accessible area of Fort Belvoir in southern Fairfax County, is the first comprehensive and truly national museum to capture, display and interpret the Army's history by telling stories through the eyes of soldiers. Named one of the "Best New Attractions in 2020" by USA Today, the museum tells over 245 years of military history through immersive multimedia exhibits.
