75th Ranger Regiment (United States) - Vietnam War

Vietnam War

The conventional approach to the history of Long Range Reconnaissance Patrol (LRRP), LRP, and Ranger unit employment in Vietnam is first to acknowledge the three chronological periods of their existence: LRRP from late 1965 to December 1967, LRP from late September 1967 to February 1969, and Ranger thereafter to the end of the war. The first period began in December 1965, with the creation of a provisional LRRP platoon by the 1st Brigade, 101st Airborne Division. The 1st Infantry Division and 173rd Airborne Brigade both formed provisional LRRP units in April and the 25th Infantry Division in June 1966. General William C. Westmoreland, commander of Military Assistance Command, Vietnam (MACV), officially authorized the creation of provisional LRRP units on 8 July 1966. Other divisions and brigades stood up provisional LRRP units during the ensuing months: the 4th and 9th Infantry Divisions in November 1966, 196th Light Infantry Brigade in January 1967, and 1st Air Cavalry Division in November 1966. The 9th Infantry Division LRRP Platoon came into being in the fall of 1966 while the division was still at Fort Riley, Kansas, and deployed to Vietnam in January 1967. This unit was expanded to a company in July 1967. The 101st Airborne Division “main body,” while still at Fort Campbell, Kentucky, converted its divisional Recondo School into a provisional LRRP unit in the summer of 1967, before the division deployed to Vietnam. This provisional company arrived in Vietnam in late November 1967.

The second period began in late June 1967, when the Chairman of the Joint Chiefs of Staff, General Earle G. Wheeler, authorized the formation of two long-range patrol companies for I and II Field Forces. Company E (Long Range Patrol), 20th Infantry (Airborne) was activated on 25 September 1967 and assigned to I Field Force and stationed at Phan Rang. The nucleus of this unit came from the 1st Brigade, 101st Airborne Division LRRP Platoon, along with soldiers from the replacement stream. Company F (Long Range Patrol), 51st Infantry (Airborne) was activated on 25 September 1967 and assigned to II Field Force with station at Bien Hoa. Its nucleus came from the LRRP platoon of the 173d Airborne Brigade, along with soldiers from the replacement stream. Each of the two field force LRP companies had an authorized strength of 230, and was commanded by a major.

In an apparent response to division commanders' tactical requirements, and bolstered by the proven combat effectiveness of the provisional LRRP units, in the fall of 1967 the Army authorized separate company designations for LRRP units in divisions and detachments in separate brigades. The divisional LRP companies were authorized 118 men and the brigade detachments 61 men. The wholesale renaming of existing divisional LRRP units occurred on 20 December 1967 in the 23d (Americal), 1st Air Cavalry, 1st Infantry, 4th Infantry, 9th Infantry, and 25th Infantry Divisions. LRP detachments were created in the 199th Light Infantry Brigade on 10 January 1968, in the 173d Airborne Brigade on 5 February 1968, and in the 3d Brigade 82d Airborne Division and 1st Brigade 5th Mechanized Division on 15 December 1968.

On 1 February 1969, the final period of the existence of these units began when the Department of the Army re-designated the LRP companies and detachments as lettered Ranger companies of the 75th Infantry Regiment under the Combined Arms Regimental System (CARS). All of the LRP companies and detachments were “re-flagged” as Ranger companies on that date, except Company D (Ranger), which was formed on 20 November 1969 upon the rotation of the Company D (Ranger), Indiana National Guard back to its home state. The third period ended when the Ranger companies were inactivated as their parent units were withdrawn from the war between November 1969 (Company O of 3d Brigade 82d Airborne Division), and 15 August 1972 (Company H of 1st Air Cavalry Division).
