Identified by its original caption, this photograph shows the Marine Guard of USS Columbia posed on deck in 'campaign dress' — broad-brimmed field hats, service shirts, and cartridge belts worn for landing-party and shore duty rather than formal dress parade. Flanked by stacked rifles and accompanied by their field drummer, these Marines represented the ship's detachment responsible for shipboard security, honor guard duties, and expeditionary landing operations during Columbia's service in the late 1890s and early 1900s.
