Ring of Steel

Ring of Steel was an Army recruiting film released sometime in the early 1940s and narrated by Spencer Tracy. The exact date of the film is not certain: Internet Archive.org says 1941, which would explain the lack of any explicit mention of World War II, whereas the Internet Movie Database gives its release date of April 7, 1942. The film uses stock footage with Tracy's voice-over narrating the story of America's military history from the perspective of the personification of the American soldier. It starts with Lexington and Concord "Where I was born" through the First World War, listing the US military's achievement and urging young men to sign up.
