"The Old Breed"
The 1st Marine Division was activated aboard the battleship Texas on 1 February 1941. It is the oldest, largest, and most decorated division in the United States Marine Corps, with nine Presidential Unit Citations (PUCs).
The 1st Marine Division is comprised of Headquarters Battalion, the 1st, 5th, 7th, and 11th Marine Regiments, 1st Reconnaissance Battalion, 1st and 3d Light Armored Reconnaissance Battalions, 1st Tank Battalion, and 3d Assault Amphibian Battalion. These units represent a combat-ready force of more than 22,000 Marines and Sailors.
Division regiments were in existence as early as March 8, 1911, when the 1st Marines were formed at Guantanamo Bay, Cuba. It saw action in Haiti in 1915, in the Dominican Republic in 1916, and throughout the Caribbean during World War I.
The 5th Marines
The 5th Marines was created in Vera Cruz, Mexico July 13, 1914. It served in Santo Domingo in 1925 and participated in 15 major engagements during World War I.

It was reactivated in 1941. The 11th Marines was formed in January 1918 at Quantico, Va., as a light artillery regiment. The regiment went to France as an infantry unit, providing a machine gun company and a guard company. Decommissioned and reactivated twice between world wars, the regiment again served as infantry in Nicaragua. Re-formed in 1940 as a full-fledged artillery unit, 11th Marines joined 1st Marine Division.
The Guadalcanal campaign : 1942
On 27 September 1944, the U.S. flag was raised over Peleliu, symbolizing that the island was secured. The honor guard was comprised of 1st Marine Division Band members. The general editor of this pamphlet, Benis M. Frank, is eighth from the left.
The first major American Pacific campaign in World War II and the first time the 1st Marine Division conducted combat operations as a division. The Division's actions during this operation won it the first of three World War II PUCs. 1st Marine Division also won PUCs for the battles of Peleliu and Okinawa. Three weeks after Japan surrendered, the Division was dispatched to North China for occupation duty. While in China, the Division had numerous encounters with the Chinese Communists.
'The Old Breed', as the Division became known, provided the Pusan Fire Brigade when war broke out in Korea and then was chosen to land at Inchon on 15 September 1950.
The Division subsequently fought into the mountains around the Chosin Reservoir. The Chinese Communists suffered more than 37,500 casualties trying to stop the Marines' march out of the 'Frozen Chosin.' These battles, and those that followed between April and September, earned the Division its fourth, fifth, and sixth PUCs.
The 2d Battalion
The 2d Battalion, 1st Marines deployed to Guantanamo Bay for two months in 1962 during the Cuban Missile Crisis. More than 11,000 Marines of the 5th Marine Expeditionary Brigade participated in the naval blockade which forced the withdrawal of the missiles from Cuba.
In 1965, 7th Marines participated in the first major engagements for American ground troops in South Vietnam. March 1966 saw 1st Marine Division Headquarters established at Chu Lai. By June, the entire Division was in South Vietnam; its zone of operation â€“ the southern two provinces of I Corps â€“ Quang Tin and Quang Ngai. Between March 1966 and May 1967, the Division conducted 44 named and unnamed operations. Major engagements included Operations HASTINGS and UNION I and II. In these operations, 1st Marine Division units decisively defeated the enemy. During the 1968 Tet Offensive, the Division was involved in fierce fighting with both Viet Cong and North Vietnamese Army elements. It successfully beat back and decimated every enemy assault in its area of operations, pursuing the enemy into his sanctuaries. It was during this period that the Division earned its seventh and eighth PUCs.
1st MAR DIV returns to California
After six hard years, the 1st Marine Division returned to California in 1971, closing another chapter of dedicated service to Corps and country. In 1975, the Division supported the evacuation of Saigon by providing food and temporary shelter at Camp Pendleton for Vietnamese refugees as they arrived in the United States. In 1990, the 1st Marine Division formed the core of the force sent to Southwest Asia in response to Iraq's invasion of Kuwait. During Operation DESERT SHIELD, the Division provided the ground combat element of I Marine Expeditionary Force in Saudi Arabia against the Iraqi threat. In 1991, the Division fought alongside the 2d Marine Division under I MEF and with the rest of the Coalition Forces in Operation DESERT STORM. In 100 hours of offensive ground combat, 1st Marine Division destroyed the enemy in its path as it led the breakthrough to Kuwait City.
Post Persian Gulf conflict
Immediately following the Persian Gulf conflict, the Division sent units to assist in disaster relief efforts in Bangladesh (Operation SEA ANGEL) and the Philippines (Operation FIERY VIGIL). In 1992, 2d Battalion, 9th Marines and the 15th MEU, brought relief to famine-stricken Somalia. The final phase of the operation involved the transition from a U.S. peacemaking force to a United Nations peacekeeping force. U.S. Marine involvement in Operation RESTORE HOPE officially ended 27 April 1993 when the humanitarian relief sector of Mogadishu was handed over to Pakistani forces. Elements of the Division ultimately participated in the extraction of U.N. forces from Somalia.
In early 2003
In early 2003, the Division deployed by air and sea to link up with its advance headquarters deployed to Kuwait under I MEF. In a high speed attack, and in conjunction with 1 U.K. Armored Division and the 3d U.S. Army Infantry Division, the Marines and Sailors conducted the deepest penetrating ground operation in Marine Corps history. Attacking to Baghdad alongside 3d ID and eventually seizing Saddam Hussein's hometown of Tikrit, the Division again showed the Marine Air-Ground team in action. The 1st Marine Division conducted stability operations in Baghdad, Tikrit, and then in south-central Iraq from May to October 2003. The Division then returned home to Camp Pendleton and 29 Palms and prepared for redeployment. These actions earned the Division its ninth PUC.
In March 2004, the 1st Marine Division relieved 82d Airborne Division in Iraq's Sunni Triangle. During Operation IRAQI FREEDOM II, the Division conducted counter-insurgency operations throughout the Al Anbar Province, culminating in Operation AL FAJR which liberated the insurgent stronghold of Fallujah and enabled the first legitimate elections to occur in Iraq. During February and March 2005, 1st and 2d Marine Divisions successfully conducted the largest relief in place in the history of the Marine Corps.
