The term 'Army Copter' refers to the UH-1 Iroquois, more commonly known as the 'Huey'. The Huey is a military helicopter that was first used by the United States Army in 1959 and has since been used by many other countries. It is most well-known for its use in the Vietnam War, where it served as a transport and medical evacuation aircraft. The Huey is still in use today, primarily for search and rescue operations.
