The following was copied from the Wikipedia for history:

The 19th Cavalry was constituted on 24 October 1967 in the Hawaii Army National Guard as a parent regiment under the Combat Arms Regimental System(CARS). It was organized and Federally recognized on 17 December 1967 at Wahiawa to consist of Troop E, part of the 29th Infantry Brigade.^[2] During the Vietnam War in May 1968, the 29th Brigade was mobilized for active Federal service to serve as the strategic reserve for United States Army Pacific.^[3] Troop E was ordered into active Federal service on 13 May 1968 at Wahiawa, under the command of Captain Kazumasa Ota.^[4] The troop spent its active service period training at Schofield Barracks, and was also equipped with the M114A1 armored fighting vehicle at the time.^[5] In June, the troop received ten M551 Sheridan tanks, the first time the Sheridan was sent outside of the continental United States.^[6][7] It was released from active service and reverted to state control on 12 December 1969.^[8]

In 1974, the troop became the first Guard unit to receive the Bell AH-1 Huey Cobra attack helicopter and was redesignated Troop E (Air).^[9] It spent its two-week annual training period in August 1980 at the Pohakuloa Training Area alongside troops of the 25th Infantry Division.^[10] Around January 1984, the troop received nine AH-1S Cobra helicopters, replacing the older Cobras.^[11][12] Between November 1984 and October 1986, it was commanded by Captain (later Major) Gary M. Hara, who later became deputy commanding general of United States Army Pacific.^[13] On 31 July 1986, one of the troop’s Bell OH-58A Kiowa helicopters crashed, slightly injuring the pilot and aerial observer.^[14] On 1 June 1989, it was withdrawn from CARS and reorganized under United States Army Regimental System (USARS) with headquarters at Fort Ruger.^[8] The regiment was disbanded in 1995 around when its last lineage document was written.^[1]
