The mission of the National Guard Museum is to acquire, preserve, protect, and display military equipment, records, relics, and memorabilia representing the heritage of the Dakota Militia and the South Dakota Army and Air National Guard. The museum also educates National Guard members and the general public about the heritage of the South Dakota National Guard both in peace and at war. The South Dakota museum is one of only 20 authorized National Guard museums in the nation. The museum is a non-profit organization which also receives a small amount of state funding. The museum is staffed by a curator and local volunteers knowledgeable about all displays.
