Taken in 1967 at Cu Chi, a major U.S. base camp in South Vietnam associated with the 25th Infantry Division, this photograph shows American soldiers building a sandbagged structure while a local Vietnamese laborer works nearby. Scenes like this — canvas tents, sandbag fortifications, and everyday base-camp labor — defined much of the daily experience of U.S. troops during the Vietnam War, far removed from combat but essential to sustaining operations in the field.
