1980s Activated on 1 December 1982 as the 22nd Marine Amphibious Unit (MAU), the 22nd Marine Expeditionary Unit (MEU) has had an impressive operational history and continues to serve as an expeditionary force in readiness. The MEU's activation was the redesignation of the 32nd MAU, a unit that regularly deployed to the
Mediterranean and
Caribbean regions for more than 20 years. On its final deployment, the MAU evacuated the
Palestine Liberation Organization from
Beirut, and was the first American unit to serve in the multi-national peace-keeping force in
Lebanon. On 22nd MAU's maiden deployment, it again visited
Beirut where the
Marines and Sailors served until May 1983, were present during the April
1983 United States embassy bombing, and began preparing for a third deployment to
Lebanon upon return to the
United States. On 18 October 1983, the MAU departed the United States, and less than two days into its trans-Atlantic voyage it was diverted to the southern
Caribbean. On 25 October 1983, the MAU participated in
Operation Urgent Fury, the invasion of the island of
Grenada, which was at that time, the largest U.S. military operation since the
Vietnam War. The 22nd MAU conducted numerous
helicopter and surface landings over three days and occupied 75 percent of the island; though the Marines constituted less than 20 percent of the total invasion force. By 2 November of that same year, the unit transited to
Beirut where it landed later that month. The MAU remained ashore until late February 1984, when the mission drew to a close, and evacuated hundreds of American citizens from the country. Throughout the rest of the 1980s, the 22nd MAU deployed on a rotation basis with the 24th and 26th MAUs, participating in numerous contingency operations and exercises. In 1986, the 22nd MAU was the third unit to deploy with the '
Special Operations-Capable' designation. On 5 February 1988, the word 'Amphibious' was replaced with 'Expeditionary' to reflect the Marine Corps' changing role in national defense and theater security.
1990s In late 1990 the 22nd MEU disbanded down to the command element during the Gulf war and reformed the summer of 1991. Saipan, Nashville, and the Harlan County were the ships they were on. In September 1991, the deployment the MEU participated in the first combined arms exercise in
Kuwait following
Operations Desert Shield and
Operation Desert Storm. This deployment returned in March 1992. Conflict in the
Balkans kept the MEU busy during subsequent deployments as the unit participated in operations
Operation Provide Promise,
Operation Deny Flight and
Operation Sharp Guard. In 1993, the MEU also served during the
United Nations’ mission to
Somalia. In April 1996, the 22nd MEU (SOC) arrived off the coast of civil war torn
Liberia in western
Africa for Operation Assured Response. The unit remained at sea until 2 Aug. which the Marines went ashore to reinforce the U.S. Embassy in
Monrovia and evacuated U.S. citizens and designated third-country nationals. The MEU (SOC) evacuated more than 1,600 civilians over the course of the next several weeks, until the 26th MEU arrived to provide relief. The MEU's deployments in 1996 and 1997 focused on West Africa as it answered the call to conduct reinforcement and evacuation missions in
Liberia,
Zaire, the
Central African Republic, the
Republic of Congo and
Sierra Leone. Additionally, the MEU continued to support Balkans peace-enforcement operations and conducted a non-combatant evacuation operation (NEO) in
Albania. In 1998, the 22nd MEU served in
Bosnia and
Kosovo, and was prepared to support operations in both Albania and Africa. Following the impact of
Cyclone Sidr on 15 November 2007, the 22nd MEU, on board moved off the coast of
Bangladesh in the
Bay of Bengal and provided
humanitarian assistance to those affected by the cyclone. The 22nd MEU deployed from May - December 2009. The MEU was composed of Marines from the
3rd Battalion, 2nd Marines and from the
Combat Logistics Battalion 22, as well as
MV-22 Osprey aircraft from
VMM-263. The MEU conducted numerous Theater Security Cooperation events in Europe and the Middle East during a deployment to the U.S. European Command and Central Command. In Europe, the Marines trained in
Bulgaria and
Greece. The 22nd MEU also made history in May 2009 when it was the first MEU to deploy with the
MV-22 Osprey aircraft tilt-rotor aircraft. During workups, the MEU experimented with different employment techniques to understand and utilize the full capability of the aircraft. The MEU conducted four separate Theater Security Cooperation events with Middle Eastern partners to build positive relationships between militaries and strengthened regional security. Near the end of the deployment, the MEU directly supported Operation Enduring Freedom by transferring the MV-22B Osprey tilt-rotor aircraft to forces on the ground, marking the first time the aircraft would support operations in Afghanistan.
2010 Haiti Earthquake After the devastating, 12 January
2010 Haiti earthquake, Marines with the 22nd MEU embarked on the
Bataan Amphibious ready group for
Haiti in order to conduct a
humanitarian assistance and disaster relief mission known as
Operation Unified Response. 22nd MEU departed Camp Lejuene on 15 January and began arriving on 18 January. The 22nd MEU was the first major Marine force to respond, managing the hardest hit area that spanned west of Port-au-Prince. Initially, the MEU conducted immediate relief operations by distributing food, water and providing medical care. Units within the MEU consist of 1,600 Marines with the
Combat Logistics Battalion 22,
3rd Battalion 2nd Marines,
Marine Heavy Helicopter Squadron 461 and the MEU Command Element, while the ARG consisted of , and . 150 Marines aboard joined the MEU, originally from the African Partnership Station Security Cooperation MAGTF, along with the
24th MEU on , , and . On 24 March, the MEU and ARG were released from their mission and sailed for home. From February to March, the MEU transitioned to sustained relief operations and focused on turning over responsibilities to the Government of Haiti and major relief organizations ashore before departing at the end of March.
2018–2019 Deployment From December 2018 to July 2019, 22nd MEU deployed to the 5th and 6th Fleet areas of responsibility as part of the KEARSARGE Amphibious Ready Ground (KSG/ARG). While deployed, 22nd MEU supported multiple operations and training exercises in the Middle East and Europe.
2020 Deployment From May to October 2020, 22nd MEU deployed to Moron Air Base, Spain as Special Purpose Marine Air Ground Task Force - Crisis Response - Africa (SPMAGTF-CR-AF). While deployed, 22nd MEU supported contingency operations in North Africa.
2025 Deployment The 22nd MEU deployed onboard the
USS Iwo Jima, the
USS San Antonio, and the
USS Fort Lauderdale to do drill and patrol duties. They were escorted by several other ships and aircraft for
Operation Southern Spear amid tensions between the United States and Venezuela just before the
2025 United States struck a Southern Caribbean boat, and now are maintaining position for the
2025 US Caribbean naval deployment ==Notable facts==
