The time periods of interest would span from Frontier times to the present. Relating the collection to military history and informing the public is another important mission of the museum.
The Wyoming Veterans Memorial Museum will honor all veterans of the National Guard Units plus former members of the Army, Navy, Air Force, Coast Guard, Marines, and Merchant Marine, regardless of their original or present place of residence. Much of the museum's collection has been obtained from veterans who now reside outside of Wyoming.
