The Minnesota Military Museum is the principal activity of the Military Historical Society of Minnesota (MHSM), a non-profit educational organization chartered to preserve and explain Minnesota’s military history. It is federally recognized as a charitable 501(c)(3) organization. MHSM operates the museum as a public–private partnership in cooperation with the Minnesota Historical Society and the Minnesota National Guard.[2] The museum, which is open to the general public year-round, is located a few blocks inside the main gate at Camp Ripley, a state-owned 53,000 acres (21,000 ha; 83 sq mi) military training center located on the Mississippi River just north of Little Falls in central Minnesota. The museum is certified by the United States Army Center of Military History[3] although its mission encompasses all branches of service.[4]
