The 302nd Cavalry Regiment was a cavalry unit of the United States Army during World War I, the interwar period, and the Cold War. It was activated in early 1918 but broken up in the middle of the year to form new artillery units. The unit was recreated as a New Jersey Organized Reserve unit during the interwar period, and was converted into a tank destroyer battalion after the United States entered World War II. Reactivated in 1971 and 1973 in the Army Reserve, it was represented by two squadrons in the 100th Division (Training).
