This photograph documents U.S. Army Signal Corps personnel practicing field cinematography and still photography, likely during training exercises in the late 1930s or early years of World War II. The Signal Corps was responsible for capturing official military motion picture and photographic records, work that would prove essential for documenting combat operations, training, and propaganda throughout the war. The officer's campaign hat and the vintage professional cine camera reflect the equipment and dress typical of the pre-war and early-war U.S. Army. Project: 218292
