The 192nd Cavalry Regiment was constituted in the Puerto Rico Army National Guard on 7 April 1964 as the 192nd Cavalry, a parent regiment in the Combat Arms Regimental System (CARS), and organized 1 May 1964 to consist of Troop E, an element of the 92nd Infantry Brigade. It was withdrawn from CARS on 27 October 1987 and reorganized under the U.S. Army Regimental System, with Troop E remaining an element of the 92nd Infantry Brigade. It was called into active Federal service in June 2003, but there is no record from readily accessible public documents indicating the length or location of its deployment.
It is unclear whether Troop E and with it the 192nd Cavalry Regiment was inactivated, deactivated, disbanded, or reflagged when the 92nd Infantry Brigade was redesignated as the 92nd Maneuver Enhancement Brigade in 2008, but in any event it was no longer listed in the Puerto Rico Army National Guard’s Table of Organization following the change.
