The 187th Airborne Infantry Regiment (Rakkasans) is a regiment of the 101st Airborne Division.

, the 1st and 3rd battalions are the only active elements of the regiment; they are assigned to the 3rd Brigade Combat Team, 101st Airborne Division.

Military operations World War II and aftermath The regiment was originally constituted as the 187th Glider Infantry Regiment on 12 November 1942, and activated on 23 February 1943 at Camp Mackall, North Carolina. It was originally a two battalion glider regiment assigned to the 11th Airborne Division, the men of the 187th trained both as glider and parachute troops. They moved to Camp Polk on 9 January 1944 for glider training. The regiment staged at Camp Stoneman, California on 29 April 1944, and departed from the San Francisco Port of Embarkation on 6 May 1944.

The regiment arrived in New Guinea on 29 May 1944 and joined the New Guinea Campaign. The regiment departed New Guinea on 11 November 1944, and arrived on Leyte on 18 November 1944 to join the Leyte Campaign.

The regiment left Leyte, and joined the Luzon Campaign by assaulting Nasugbu Point Luzon on 31 January 1945, blocking Japanese forces as part of the advance on Manila from the south. From then until April 1945, the 187th fought their way from Nichols Field, Fort William McKinley, and Manila to Mount Macolod and Malepunyo.

In May 1945, the 187th moved into Lipa to refit, rebuild, and prepare for Operation Downfall, the planned invasion of Japan. At this time, the 3rd Battalion was formed and the regiment was redesignated a para-glider regiment.

The regiment was attached to the Provost Marshal General, U.S. Army Forces Far East from 1 June 1945 through 27 July 1945 at Manila. The campaigns in the Philippines were declared completed on 4 July 1945, and the regiment moved to Okinawa on 12 August 1945 for occupation duty. This is where the unit gained its name; , which means "Parachute" in Japanese, when it was the only unit to parachute onto Japanese soil at the time. With soldiers landing in close proximity to local landmarks featuring toriis the 187th adopted the torii as an unofficial part of the unit identity. After the war ended on 14 August 1945, the regiment subsequently moved to Japan on 30 August 1945, and was alleged to be the first foreign ground combat unit to enter that nation.

In April 1949, the regiment returned to the United States and was stationed at what was then Camp Campbell, Kentucky. It was redesignated the 187th Airborne Infantry Regiment on 30 June 1949 and remained assigned to the 11th Airborne Division. In early 1950, the 187th participated in "Operation Swarmer", the largest peacetime airborne maneuver in history.

Korean War

The 187th was selected as an airborne regimental combat team responding to the North Korean invasion of South Korea. On 1 August 1950 the regiment became the 187th Airborne Regimental Combat Team (ARCT) when supporting units were added and deployed to Japan, arriving on 20 September 1950. The advance party of the 3rd Battalion of the Rakkasans was the first to arrive in South Korea, arriving at Kimpo Airfield on 23 September. On 24 September, it was placed under the operational control of the First Marine Division, relieving the 2d Battalion of the 7th Marine Regiment, arriving almost a week after Douglas MacArthur's surprise landing at Inchon on 17 September 1950.

One month later, on 20 October 1950, the regiment made successful combat parachute assaults near the towns of Sukchon and Sunchon, North Korea as part of the Battle of Yongju. The published purpose of that drop was to capture members of the North Korean Government fleeing Pyongyang and also to free American POWs being moved from Pyongyang toward the Manchurian border. Neither objective was realized but were followed by battles at Suan, Wonju, Kaesong, Munsan-ni, and Inje.

The 187th led the second and last parachute assault in Korea on 23 March 1951 as part of Operation Tomahawk.

Under BG Thomas J. H. Trapnell, it redeployed to Japan on 26 June 1951 where it became a strategic reserve but returned to Korea on 24 May 1952 to assist in the suppression of the prisoner rebellion at the Geoje POW Camp where prisoners had forcibly seized and held Brigadier General Francis Dodd, camp commandant, hostage for four days from 7 May 1952. After this, it once more returned to Japan on 18 October 1952 and made its final return to Korea on 22 June 1953. From late 1952 to 1953 the 187th was commanded by Brigadier General (later General) William Westmoreland. The unit returned to the United States in July 1955 and, the following year, became part of the newly reactivated 101st Airborne Division, Fort Campbell, KY.

Many personnel from the 511PIR in the 11th Airborne Division were transferred to the 187th ARCT to bring it up to full strength for overseas deployment.History of the 511th Airborne Regiment , The Drop Zone

Four members of the 187th were awarded the Medal of Honor for their actions in the Korean War: Corporal Lester Hammond, Jr.(KIA), Corporal Rodolfo P. Hernandez, Corporal Joe R. Baldonado(KIA) and Private First Class Richard G. Wilson(KIA).Flanagan, p. 345.

The 1950s and early 1960s were a turbulent time for the Rakkasans, they returned to the US in 1955, this time to Fort Bragg, North Carolina. As part of a larger realignment of the army, under the Pentomic Division concept, the Rakkasans road marched to Fort Campbell in February 1956 to serve as the nucleus of the newly reactivated 101st Airborne Division.

Post-Korean War and Air Mobility When the Pentomic concept that replaced regiments and battalions with battle groups was introduced in 1957, Companies A, B, and C of the 187th Airborne Infantry Regiment were redesignated as HHCs of the 1st, 2d, and 3d Airborne Battle Groups, 187th Infantry, respectively. The 1st ABG, 187th Infantry was assigned to the 11th Airborne Division in Germany from 1 March 1957 to 1 July 1958, when the 11th was inactivated and reflagged as the 24th Infantry Division. During its assignment to the 24th it was involved in the Lebanon intervention. On 8 February 1959 it was relieved from the 24th, rotated back to the United States and was assigned to the 82d Airborne Division at Fort Bragg, NC. Its colors were inactivated on 25 May 1964 and concurrently consolidated with the 1st Battalion, 187th Infantry (constituted and activated 1 February 1964 at Fort Benning, Georgia, as an element of the 11th Air Assault Division, and the consolidated unit designated as the 1st Battalion, 187th Infantry, an element of the 11th Air Assault Division (Test) at Fort Benning, GA. It was inactivated on 30 June 1965 when the 11th Air Assault Division and 2d Infantry Division were combined to form the 1st Cavalry Division (Airmobile), during which time the elements of both the 11th and 2d were reflagged with new designations.

The 2d ABG, 187th Infantry remained assigned to the 101st Airborne Division and was inactivated on 1 February 1964 when the Army abandoned the Pentomic structure in favor of brigades and battalions.

The 3d ABG, 187th Infantry was not active during the Pentomic era. The colors were redesignated on 1 February 1963 as HHC, 3d Battalion, 187th Infantry, assigned to the 11th Air Assault Division (Test) at Fort Benning, GA, and activated on 7 February 1963. Over the next year, 3rd Battalion, 187th Infantry Regiment served as a test unit to help validate the Army's airmobile concept. It was relieved from the 11th on 1 February 1964 and the colors were assigned to the 101st Airborne Division at Fort Campbell, KY. There was no transfer of troops or equipment; instead, the existing 3–187th at Fort Benning was reflagged as 1–187th.

Vietnam War The Rakkasans moved back to Fort Campbell, Kentucky in February 1964, to serve as part of the 3rd Brigade, 101st Airborne Division. In December 1967 the 3d Battalion deployed to Vietnam, alongside 1st and 2d Battalion, 506th Infantry. Over the next four years the Iron Rakkasans fought in twelve major campaigns, conducting numerous air assaults and search and destroy missions. During one such mission in March 1968 Captain Paul W. Bucha, commander of D Company, received the Medal of Honor when he crawled through a hail of fire to single-handedly destroy a machine gun bunker with grenades near Phuoc Vinh, Vietnam. When the battalion colors returned to Fort Campbell the unit had distinguished itself by earning two Valorous Unit Awards, and its third and fourth Presidential Unit Citations for the battles of Trang Bang and Dong Ap Bia Mountain (commonly known as "Hamburger Hill"). The Iron Rakkasans emerged from the Vietnam War as the country's most highly decorated airborne battalion.

The 3-187th Infantry's exploits from 10 to 20 May 1969 on hill 937 in the A Shau Valley were depicted in a 1987 movie using the hill's nickname Hamburger Hill as the title. For this action the unit received the Presidential Unit Citation.

Post Vietnam When the 101st returned from Viet Nam, most of its personnel in the rank of staff sergeant and below were discharged upon arrival at Oakland, California, or Seattle, Washington. What remained largely consisted of a command group of staff officers and senior NCOs. The division settled into buildings recently vacated by the "U.S. Army Training Center, Fort Campbell, Kentucky."

When the 101st was rebuilt, the separate 173d Airborne Brigade was inactivated and its assets used to form the 3d Brigade as an airborne unit consisting of 1–503d INF, 2–503d INF, and 3–187th INF. The partial airborne capability also extended to supporting units of the division. This lasted only until April 1974 when The Airmobile Badge (renamed Air Assault Badge later that year) was introduced.
