On 23 December 1919 an order was issued on the formation of a museum-exposition "Life of the Red Army and Fleet" in the same location, whose purpose was to Inform the public about the achievements by post-October Revolution Soviet Russia.

In 1920 another exhibition was organised and dedicated to the 2nd Congress of the Communist International[citation needed] in Moscow about the life and deeds of the Soviet Republic and its young armed forces which defend the conquests of the proletariat.

In 1921 the exposition was transformed into the Museum of the Red Army and Fleet, and it was moved to Vozdvizhenka 6 in 1922, into a building (demolished in the 1930s), opposite today's Russian State Library.

Part of the Great Patriotic War section is devoted to the Soviet Union's allies on the Western Front.

A life-size diorama includes a Jeep pulling a field-gun in front of a wall-sized photograph of Omaha Beach.
