Photographed in South Vietnam around 1963, this Bell UH-1B Huey named 'Prissy' carries an externally mounted 2.75-inch rocket pod, representing the U.S. Army's earliest experiments in helicopter gunship warfare. Units like the pioneering Utility Tactical Transport Helicopter Company pushed the boundaries of rotary-wing combat aviation, laying the groundwork for the dedicated attack helicopters that would follow later in the Vietnam War.
