A helicopter crewman poses beside a rocket-armed UH-1 Huey gunship at a Southeast Asian airfield during the Vietnam War. Helicopters bearing the 'Scarface' callsign — flown by U.S. Marine Corps squadrons — provided close air support and extraction cover for MACV-SOG reconnaissance teams during clandestine cross-border missions such as Operation Tailwind (1970), one of the most highly classified American ground operations of the war.
