Provisional officer training corps assembled at the Presidio

1918

A panoramic group portrait of the provisional reserve officer training corps at the Presidio of San Francisco, made during the American mobilization for the First World War. The Presidio was the Army's main West Coast post, and camps like this one turned civilians into commissioned officers in a matter of weeks. The plate is held by NPGallery, the National Park Service image archive; the photographer is unrecorded.
