The museum’s displays follow the military in Montana from the arrival of the Lewis and Clark army expedition in 1805, through the Indian Wars, the Spanish-American War, World Wars I and II, the Korean Conflict, the Vietnam War, Desert Storm and various peacekeeping operations.

The Montana Military Museum, at Fort William Henry Harrison located in Helena, Montana, operates under a memorandum of agreement between the Department of Military Affairs, State of Montana and the Montana National Guard Museum Activity and the Fort William Henry Harrison Museum Foundation. The museum is a non-profit membership organization and is an all volunteer effort to honor brave Montanans who served the State of Montana and the Nation.

The true soldier fights not because he hates what is in front of him, but because he loves what is behind him.”

G.K. Chesterton
