The 19th Cavalry Regiment ("Na Lele Lio", literally "The Flying Horses" in Hawaiian) was a United States Army parent cavalry regiment, represented in the Hawaii Army National Guard by Troop E, 19th Cavalry, part of the 29th Infantry Brigade at Wahiawa. Constituted and organized in 1967, the regiment was called up during the Vietnam War but did not go overseas, and became an air cavalry unit in the early 1970s. It was disbanded in 1995.
