Vietnam Zippo factory engraved on the front with a depiction of a UH-1N twin-engine Huey helicopter in flight above the text «UH-1N», and the words «TWIN ENGINE HUEY TEAM» above the colored insignia of Marine Light Helicopter Squadron 167 (HML-167).
Marine Light Helicopter Squadron-167 operated UH-1 helicopters in Vietnam from 1968 until June 1971, providing troop transport, medical evacuation, and close air support for U.S. Marine Corps forces while based at Marble Mountain Air Facility near Da Nang. On 15 June 1971, the squadron’s last two aircraft departed the Republic of Vietnam aboard USS Dubuque, marking the end of its Vietnam deployment. Shortly after, HML-167 was transferred to MCAS(H) New River, Jacksonville, North Carolina, becoming part of MAG-26, 2d Marine Aircraft Wing, and in April 1972 received the Marine Corps’ first UH-1N, assuming the role of primary UH-1N squadron, training unit, and model manager for the aircraft.
