The division deployed into Auckland, New Zealand, between January and March 1943. In June of that year, it moved onto Guadalcanal for additional training, stopping first at Efate, New Hebrides for rehearsals (16-20 October 1943) and Santo, New Hebrides (21-29 October 1943) for shipboard-staging. 1 November 1943 saw the division land as part of the Battle of Bougainville and fight on the island until their last unit to arrive, the 21st Marine Regiment, embarked on 9 January 1944. During the course of the battle the division had about 400 Marines killed.[5]
The division returned to Guadalcanal in January 1944 to rest, refit, and retrain. The next operation in which the division took part was the Battle of Guam. From 21 July 1944 until the last day of organized fighting on 10 August, the division fought through the jungles on the island of Guam. During these 21 days of fighting, the division captured over 60 square miles (160km2) of territory and killed over 5,000 enemy soldiers.[6] The next two months saw continuous mopping up operations in which the Marines continued to engage leftover Japanese forces. At the end of the battle the division had sustained 677 Marines killed, 3,626 wounded, and nine missing.[7]
The division remained on the island of Guam for training, until it embarked as part of the landing force for the Battle of Iwo Jima. The 3rd Marine Division was initially in reserve for the battle.[8] However, the division was committed one regiment at a time when the initial regiments that landed there needed to be relieved.
The 21st Marines came ashore on 21 February[8] followed by the 9th Marines, 12th Marine Regiment, 3rd Tank Battalion, on 24 February.[9] The Marines of these two infantry regiments, supported by the artillery of the 12th Marine Regiment and tanks of the 3rd Tank Battalion, fought on Iwo Jima until the end of organized resistance on 16 March and the subsequent mopping up operations for the next month. All elements of the division were back on Guam by 17 April 1945.[10] The fighting on Iwo Jima cost the 3rd Marine Division 1,131 killed in action and another 4,438 wounded.[11]
During the war, the 3rd Marine Division had three Seabee Battalions assigned to it. The 25th Naval Construction Battalion (NCB) was posted to 19th Marines as the third battalion of the regiment. These landed on Bougainville, as did the 71st NCB which was assigned as the 3rd Division's shore party there.[13]
The 25th NCB also landed during the assault on Guam as the shore party to the 3rd Marine Regiment, after which the 19th Marines were deactivated, and the 25th NCB was reassigned. The 62nd NCB was then posted TAD to the 3rd for Iwo Jima. They were in the reserve, but they became the lead battalion in getting airfield No. 1 operational, after of the many casualties taken by the primary assault Seabees,[14] the 133rd NCB.[citation needed]
Korean War
The division was reactivated on 7 January 1952 at Camp Pendleton, California, using the assets of the 3d Marine Brigade activated in June 1951. Immediately after its activation and still in its organizational state, the division began intensive combat training, including new tactics and maneuvers based on lessons learned in the then-ongoing Korean War. During the remaining part of 1952 elements of the division participated in numerous exercises and training problems, including vertical envelopment (helicopter landing), airborne operations and attack, and defense against atomic weapons and missiles.[citation needed]
In August 1953 the division arrived in Japan to support the 1st Marine Division in the defense of the Far Eastern area. In March 1956 the division moved to Okinawa and remained there in a readiness posture until 1965.[citation needed] The 3rd Marine Division moved to Okinawa in June 1955 making an amphibious landing.
Nearly 8,000 PAVN were killed during this time period. The Marines suffered over 1400 killed and over 9,000 wounded. There were five Medals of Honor awarded and nearly 40 Navy Crosses given during this period of time. For extraordinary heroism in the Republic of Vietnam from 8 March 1965 to 15 September 1967, the division was awarded the Navy Presidential Unit Citation.[16]
During the 1968 Tet Offensive, the division conducted operations along the DMZ with a portion of the division fighting in the Battle of Huế. At the time, 3rd Marine Division intelligence estimated the combat strength of PAVN and Viet Cong (VC) forces in the DMZ area was 40,943 troops.[17] The PAVN and VC stepped up their attacks by fire on every combat base in the division area of operations. This included daily attempts at interdiction of naval traffic on the Cua Viet River near Đông Hà. The division had to invest many of its assets to open the Cua Viet River to traffic. BLT 5/l, the Landing Force of SLF B, remained under the operational control (OPCON) of the division throughout February 1968. BLT 3/l continued Operation Saline under operational control of the 1st Amphibian Tractor Battalion with the mission of clearing the area adjacent to the Cua Viet River between Cua Viet and Đông Hà. BLT 2nd Battalion, 4th Marines, the Landing Force of SLF A, remained under operational control of the division throughout the month. BLT 2/4 conducted operations in the Lancaster II and Kentucky areas.[18]
During the Vietnam War, the 3rd Marine Division suffered 6,869 men killed in action.[19]
3d Marine Regiment, 3d Marine Division was one of the first combat forces to deploy to Saudi Arabia in response to the Iraqi invasion of Kuwait on 2 August 1990. The regiment, which became known as task Force Taro in honor of the state and people of Hawaii, became the first American unit to be engaged by Iraqi artillery, rocket and missile fire on 18 January 1991. Task Force Taro countered the Iraqi supporting attacks by conducting artillery raids into Kuwait as the first ground offensive actions of the war. Task force Taro was instrumental in the recapture of Khafji, was the first unit to advance into Kuwait, conducted the only helicopter borne assault of the war and secured the Marine Corp’s final objective of the war, Kuwait International Airport.
Following the cease-fire on 28 February 1991, the regiment redeployed to Saudi Arabia and subsequently completed its strategic redeployment to Hawaii two months later.
