The museum collected material relating to the Latvian Riflemen and World War I.

In June 1919 the museum restored operations at the Powder Tower in old town Riga.

However, the museum had during its existence gathered valuable, representative Soviet artifacts for its collections.

There are major exhibits on Latvia's involvement in the first and second world wars covering multiple battles in great detail.

Latvia's recent military activities are also explored, including involvement in United Nations peacekeeping missions.
