Entering service in the U.S. Army in 1959, the UH-1 “Iroquois,” known by its crews as the “Huey,” served throughout the Vietnam War and pioneered the use of air-mobile warfare. Up to this point in military history, troops walked into battle, rode on horseback, or were transported in vehicles. With the arrival of the “Huey,” up to 12 fully equipped troops flew quickly in and out of the battle zone. Once the troops disembarked, the helicopter then served as a resupply aircraft, medevac, and close air support gunship. The “Huey’s” signature sound as it cut through the air is recognized by many as the sound of the Vietnam War.
