MajorCommands.jpg

Marine Corps Installations West and Marine Corps Base Camp Pendleton merged into a single command, April 5, 2012. Marine Corps Installations West consists of five Marine Corps bases and stations in the Southwestern United States, including MCB Camp Pendleton, MCAS Camp Pendleton, MCAS Miramar, MCAS Yuma and MCLB Barstow. MCI West also performs various support functions for MCAGCC Twentynine Palms, MWTC Bridgeport and MCRD San Diego. MCI-West provides the installation and training infrastructure to enable Marine Corps air and ground forces to develop and sustain operational readiness. To this end, the primary mission is to support training, sustaining, and deploying the warfighter, and to provide their families with services that enrich their lives.

In order to remain the nation’s premier expeditionary force in readiness, Marines must train as they fight, with access to interconnected sea, land, and air ranges. The varied terrain and climate of the Southwest make it an ideal place to prepare Marines for combat. Forty percent of the Marine Corps’ combat power resides in the Southwest, along with 85% of its ground training areas and ranges, and 80% of its land holdings. Even more significant, 95% of Marines train in the region (predominantly California) before deploying oversees.

I Marine Expeditionary Force (I MEF)

I Marine Expeditionary Force (I MEF) was activated in Okinawa, Nov.8, 1969, and was reassigned to Camp Pendleton April 14, 1971.

I MEF is composed of I Marine Expeditionary Force, Headquarters Group, 1st Marine Expeditionary Brigade, 1st Marine Division, 3rd Marine Aircraft Wing, 1st Marine Logistics Group and the 11th, 13th and 15th Marine Expeditionary Units.

I MEF is expeditionary in nature, planning for and conducting worldwide missions across the entire spectrum of conflict, from humanitarian assistance to direct combat operations and major theater warfare. This versatility makes I MEF one of the premier forces in readiness in the United States military. The I MEF staff plans for, conducts and supervises the training of Marine Air/Ground Task Force elements as required to meet these contingency taskings. Furthermore, I MEF is charged with developing standing operating procedures for all aspects of Marine Air/Ground Task Force operations and for the promulgation of contingency and warplans.

In 2004, I MEF commanded 43,000 U.S. and United Kingdom Forces in Iraq and Kuwait during Operation Iraqi Freedom II. In 2003, I MEF commanded more than 80,000 U.S. and U.K. forces in Iraq and Kuwait during Operation Iraqi Freedom. In addition, I MEF supported Operation Enduring Freedom in Afghanistan in 2002, participated in Operation Restore Hope in Somalia in 1993 and participated in Operations Desert Shield and Desert Storm in Southwest Asia from 1990 to 1991.

Recently, I MEF has participated in Operation Iraqi Freedom and Operation Enduring Freedom.

Today, as a formidable organization within Marine Air/Ground Task Force concept, I MEF task organizes 50,000 Marines and sailors to conduct worldwide operations.

1st Marine Division

The 1st Marine Division was activated aboard the battleship USS Texas, Feb. 1, 1941. It is the oldest and most decorated division-sized unit in the United Stated Marine Corps. Division regiments were in existence as early as March8, 1911, when the 1st Marine Regiment was 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 Marine Regiment was created at Vera Cruz, Mexico on July 13, 1914. It served in Santo Domingo in 1925 and participated in 15 major engagements during World War I. These included Belleau Wood, Chateau and Chiercy Mihiel. On Aug. 11, 1917, 7th Marines was activated in Philadelphia, Penn. It spent the duration of World War I in Cuba and was disbanded after the war. It was reactivated in 1941.

The 11th Marine Regiment 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 an infantry unit in Nicaragua. Re-formed in 1940 as a full-fledged artillery unit, 11th Marines joined 1st Marine Division.

Guadalcanal was the first major American offensive of World War II. Launched Aug. 7, 1942, this operation won the Division its first of three World War II Presidential Unit Citations. The following citations were won at Peleliu and Okinawa.

“The Old Breed” was the unit chosen to land at Inchon, Korea, Sept. 15, 1950, adding another PUC to its list of decorations. A fifth PUC was for the Division’s “Attack in the opposite direction,” fighting its way out of the Chosin Reservoir against seven Communist Chinese divisions. The Chinese suffered an estimated 37,500 casualties trying to stop the Marines’ march out of the “Frozen Chosin.” Battles between April and September earned the division its sixth PUC.

The 2nd Battalion, 1st Marines returned 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.

Less than three years later, the Division was again on the move. In 1965, 7th Marines participated in Operations Starlight and Piranha, 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 — the southern two provinces of ICorps — Quang Tin and Quang Ngai.

Between March and October 1966 to May 1967, the Division conducted 44 named 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 was successful in beating back enemy assaults in its operation areas.

After six hard years of combat, 1st Marine Division returned home to Camp Pendleton 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, 1st Marine Division formed the nucleus of the massive force sent to Southwest Asia in response to Iraq’s invasion of Kuwait. During Operation Desert Shield, the Division supported the I Marine Expeditionary Force in the defense of Saudi Arabia from the Iraqi threat. In 1991, the Division went on the offensive with the rest of Coalition Forces in Operation Desert Storm. In 100 hours or ground offensive combat, 1st Marine Division helped to liberate Kuwait, smashing the Iraqi Army in the process.

Immediately following the Persian Gulf conflict, the Division sent units to assist in relief efforts following a typhoon in Bangladesh (Operation Sea Angel) and a volcanic eruption in the Philippines (Operation Fiery Vigil).

In December 1992, Operation Restore Hope, bringing relief to famine-stricken Somalia, kicked off with the early morning amphibious landing of Marines from the Camp Pendleton-based 15th Marine Expeditionary Unit, which was supported by Battalion Landing Team, 2nd Battalion, 9th Marines. More than 15,000 metric tons of food was successfully distributed from 398 different food sites in the city during the operation. 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 April 27, 1993, when the humanitarian relief sector of Mogadishu was handed over to Pakistani forces.

The 1st Marine Division participated in Operation Enduring Freedom after the attacks of Sept.11, 2001. In March 2003, the Marines brought freedom to the oppressed people of Iraq during Operation Iraqi Freedom. The Division was the tip of the spear during the combat phase of the operations.

Today the 1st Marine Division is a multi-role, expeditionary ground combat force. The Division is employed as the ground combat element (GCE) of I MEF or may provide task organized forces for assault operations and such operations as may be directed. The 1st Marine Division must be able to provide the ground amphibious forcible entry capability to the naval expeditionary force (NEF) and to conduct subsequent land operations in any operational environment. The 1st Marine Division is currently composed of 1st, 5th, 7th and 11th Marines; Headquarters Battalion; 3rd Assault Amphibian Battalion; 1st and 3rd Light Armored Reconnaissance Battalions; 1st Combat Engineer Battalion; 1st Tank Battalion; and 1st Reconnaissance Battalion.

The amphibious assault vehicles are primarily used to transport personnel in tactical operations. The battalion is located in Camp Del Mar (21) Area.

The Division has two light armored reconnaissance battalions. The mission of an LAR battalion is to conduct reconnaissance, security and economy of force operations, and within its capabilities, limited offensive or delaying operations that exploit the unit’s mobility and firepower. 1st LAR Battalion was activated May 31, 1985, and is located at Las Flores (41) Area. The 3rd LAR Battalion was activated on Sept.11, 1986, and is located at Twentynine Palms.

The Division reactivated the 1st Reconnaissance Battalion on June 8, 2000, but the battalion was originally activated on March 1, 1937. It now calls the Margarita (33) Area home. Before 1944, Marine Recon was primarily composed of scout/sniper units. In April 1944, a two-company amphibious reconnaissance battalion was formed with the mission of conducting beach reconnaissance and hydrographic survey. Today, the battalion performs a wide variety of tactical and special operation in support of the Division.
