The formation traces its history to the 71st Infantry Brigade of the 36th Infantry Division in World War I, when it had the 141st and 142nd Infantry Regiments, along with the 132nd Machine Gun Battalion, assigned.
The 71st Airborne Brigade consisted of three airborne infantry battalions:[6]
The 71st Airborne Brigade (separate) and its successor 36th Airborne Brigade reinforced the 82nd Airborne Division as a 4th Brigade. All 3,300 troopers of the 71st Brigade were authorized to be jump-qualified. On 1 November 1973, the brigade was inactivated and a reduced number of its personnel and amount of equipment were used to activate the 36th Airborne Brigade, a TDA headquarters.[7] The brigade only had two battalions: 1-143d and 2-143d. On 1 April 1980 the brigade was inactivated and the two battalions were reorganized and reflagged as other types of units. Company A of 2-143d formed Company G (Ranger), 143d Infantry,[8] a corps-level LRRP unit (later LRS)[9] that remained active until 2001.[10][11]
