A gun crew hauls a wheeled artillery piece across a training ground near Manila, Philippines, in this prewar-era photograph. Dressed in informal white t-shirts rather than full uniform, soldiers combine muscle power and coordinated effort to move heavy ordnance — a common scene at U.S. Army posts in the Philippine Islands during the 1930s and early 1940s, when gun drills like this one prepared crews for the demands of coastal and field artillery service.
