509TH Parachute Infantry Regiment
The 509th Infantry Regiment, known as the “Geronimos,” holds the distinction of being the first American parachute infantry unit to see combat in World War II. Its predecessors made the Army’s first combat parachute assault during Operation Torch and later fought in Italy, Southern France, and the Battle of the Bulge. Today, the regiment’s active battalions serve in very different roles: 1-509 Infantry at the Joint Readiness Training Center and 3-509 Infantry with the 11th Airborne Division in Alaska.
The 509th Parachute Infantry Battalion, forerunner of the modern regiment, originated as the 504th Parachute Infantry Battalion in 1941 and was redesignated in 1942. On 8 November 1942, the unit executed the first U.S. Army combat parachute assault near Oran during Operation Torch.
The 509th later fought in Italy, made a combat jump near Avellino in September 1943, participated in the airborne assault in Southern France during Operation Dragoon, and fought in the Battle of the Bulge.
Cold War and Beyond
Postwar 509th units served in Europe and elsewhere as the Army reorganized its airborne forces. The battalion that had been known as 1-509 Infantry in Italy was redesignated before Operation Urgent Fury; therefore, 1-509 should not be credited as a participating battalion in the 1983 Grenada operation.
