Mission
As outlined in and as originally introduced under the National Security Act of 1947, three primary areas of responsibility for the U.S. Marine Corps are: * Seizure or defense of advanced naval bases and other land operations to support naval campaigns; * Development of tactics, technique, and equipment used by amphibious landing forces in coordination with the Army and Air Force; and * Such other duties as the President or Department of Defense may direct. This last clause derives from similar language in the Congressional acts ''"For the Better Organization of the Marine Corps"'' of 1834, and ''"Establishing and Organizing a Marine Corps"'' of 1798. In 1951, the House of Representatives' Armed Services Committee called the clause "one of the most important statutory – and traditional – functions of the Marine Corps". It noted that the Corps has more often than not performed actions of a non-naval nature, including its famous actions in Tripoli, the War of 1812,Historical mission
The Marine Corps was founded to serve as an infantry unit aboard naval vessels and was responsible for the security of the ship and its crew by conducting offensive and defensive combat during boarding actions and defending the ship's officers from mutiny; to the latter end, their quarters on the ship were often strategically positioned between the officers' quarters and the rest of the vessel. Continental Marines manned raiding parties, both at sea and ashore. America's first amphibious assault landing occurred early in the Revolutionary War on 3 March 1776 as the Marines gained control ofCapabilities
The Marine Corps fulfills a critical military role as an amphibious warfare force. It is capable of asymmetric warfare with conventional, irregular, and hybrid forces. While the Marine Corps does not employ any unique capabilities, as a force it can rapidly deploy a combined-arms task force to almost anywhere in the world within days. The basic structure for all deployed units is a Marine Air-Ground Task Force (MAGTF) that integrates a ground combat element, an aviation combat element and a logistics combat element under a common command element. While the creation of joint commands under the Goldwater–Nichols Act has improved inter-service coordination between each branch, the Corps's ability to permanently maintain integrated multi-element task forces under a single command provides a smoother implementation of combined-arms warfare principles. The close integration of disparate Marine units stems from an organizational culture centered on the infantry. Every other Marine capability exists to support the infantry. Unlike some Western militaries, the Corps remained conservative against theories proclaiming the ability of new weapons to win wars independently. For example,Doctrine
Two small manuals published during the 1930s established USMC doctrine in two areas. The '' Small Wars Manual'' laid the framework for Marine counter-insurgency operations from Vietnam to Iraq andHistory
Foundation and American Revolutionary War
The United States Marine Corps traces its roots to the Continental Marines of the American Revolutionary War, formed by Captain Samuel Nicholas by a resolution of the Second Continental Congress on 10 November 1775, to raise two battalions of marines. This date is celebrated as the United States Marine Corps birthday, birthday of the Marine Corps. Nicholas was nominated to lead the Marines by John Adams. By December 1775, Nicholas raised one battalion of 300 men by recruitment in his home city of Philadelphia. In January 1776, the Marines went to sea under the command of Commodore Esek Hopkins and in March undertook their first amphibious landing, the Raid of Nassau, Battle of Nassau in the Bahamas, occupying the British port of Nassau for two weeks. On 3 January 1777, the Marines arrived at the Battle of Princeton attached to General John Cadwalader (general), John Cadwalader's brigade, where they had been assigned by General George Washington; by December 1776, Washington was retreating through New Jersey and, "in desperate need of veteran soldiers," had ordered Nicholas and the Marines to attach themselves to the Continental Army. The Battle of Princeton, where the Marines along with General Cadwalader's brigade were personally rallied by Washington, was the first land combat engagement of the Marines; an estimated 130 marines were present at the battle. At the end of the American Revolution, both the Continental Navy and Continental Marines were disbanded in April 1783. The institution was resurrected on 11 July 1798; in preparation for the Quasi-War with French First Republic, France, Congress created the United States Marine Corps. Marines had been enlisted by the United States Department of War, War Department as early as August 1797 for service in the newly-built frigates authorized by the Congressional "Act to provide a Naval Armament" of 18 March 1794, which specified the numbers of marines to recruit for each frigate. The Marines' most famous action of this period occurred during the First Barbary War (1801–1805) against the Barbary pirates, when William Eaton (soldier), William Eaton and First Lieutenant Presley O'Bannon led 8 marines and 500 mercenary, mercenaries in an effort to capture Tripoli, Libya, Tripoli. Though they only reached Battle of Derna (1805), Derna, the action at Tripoli has been immortalized in the Marines' Hymn and the Mameluke sword carried by Marine officers.War of 1812 and afterward
During the War of 1812, Marine detachments on Navy ships took part in some of the great frigate duels that characterized the war, which were the first and last engagements of the conflict. Their most significant contribution was holding the center of General Andrew Jackson's defensive line at the 1815 Battle of New Orleans, the final major battle and one of the most one-sided engagements of the war. With widespread news of the battle and the Capture of HMS Cyane and HMS Levant, capture of HMS ''Cyane'', HMS ''Levant'' and Capture of HMS Penguin, HMS ''Penguin'', the final engagements between British and U.S. forces, the Marines had gained a reputation as expert marksman, marksmen, especially in defensive and ship-to-ship actions. They played a large role in the 1813 Second Battle of Sacket's Harbor, defense of Sacket's Harbor, New York and Battle of Craney Island, Norfolk and Portsmouth, Virginia, also taking part in the 1814 Battle of Plattsburgh, defense of Plattsburgh in the Champlain Valley during one of the final British offensives along the Canadian-U.S. border. The battle of Bladensburg, fought 24 August 1814, was one of the worst days for American arms, though a few units and individuals performed heroic service. Notable among them were Commodore Joshua Barney's 500 sailors and the 120 marines under Captain Samuel Miller USMC, who inflicted the bulk of British casualties and were the only effective American resistance during the battle. A final desperate Marine counter attack, with the fighting at close quarters, however was not enough; Barney and Miller's forces were overrun. In all of 114 marines, 11 were killed and 16 wounded. During the battle Captain Miller's arm was badly wounded, for his gallant service in action, Miller was brevetted to the rank of Major USMC. After the war, the Marine Corps fell into a malaise that ended with the appointment of Archibald Henderson as its fifth commandant in 1820. Under his tenure, the Corps took on expeditionary duties in the Caribbean, the Gulf of Mexico, Key West, West Africa, the Falkland Islands, and Sumatra. Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army. Instead, Congress passed the ''Act for the Better Organization of the Marine Corps'' in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy. This would be the first of many times that the independent existence of the Corps was challenged. Commandant Henderson volunteered the Marines for service in the Seminole Wars of 1835, personally leading nearly half of the entire Corps (two battalions) to war. A decade later, in the Mexican–American War (1846–1848), the Marines made their famed Battle of Chapultepec, assault on Chapultepec Palace in Mexico City, which would be later celebrated as the "Halls of Montezuma" in the Marines' Hymn. In fairness to the U.S. Army, most of the troops who made the final assault at the Halls of Montezuma were soldiers and not marines. The Americans forces were led by Army General Winfield Scott. Scott organized two storming parties of about 250 men each for 500 men total including 40 marines. In the 1850s, the Marines engaged in service in Panama and Asia and were attached to Commodore Matthew C. Perry, Matthew Perry's East India Squadron on its historic trip to the Far East.American Civil War to World War I
The Marine Corps played a small role in the American Civil War, Civil War (1861–1865); their most prominent task was blockade duty. As more and more states Ordinance of Secession, seceded from the Union (American Civil War), Union, about a third of the Corps's officers left the United States to join the Confederate States of America, Confederacy and form the Confederate States Marine Corps, which ultimately played little part in the war. The battalion of recruits formed for the First Battle of Bull Run performed poorly, retreating with the rest of the Union forces. Blockade duty included sea-based amphibious operations to secure forward bases. In late November 1861, Marines and sailors landed a reconnaissance in force from at Tybee Island, Georgia, to occupy the lighthouse and Martello tower on the northern end of the island. It would later be the Army base for Siege of Fort Pulaski, bombardment of Fort Pulaski. In April and May 1862, Marines participated in Capture of New Orleans, the capture and occupation of New Orleans and the occupation of Baton Rouge, Louisiana, key events in the war that helped secure Union control of the lower Mississippi River basin and denied the Confederacy a major port and naval base on the Gulf Coast of the United States, Gulf Coast. The remainder of the 19th century was marked by declining strength and introspection about the mission of the Marine Corps. The Navy's transition from sailing ship, sail to steamboat, steam put into question the need for Marines on naval ships. Meanwhile, Marines served as a convenient resource for interventions and landings to protect American interests overseas. The Corps was involved in over 28 separate interventions in the 30 years from the end of the American Civil War to the end of 19th century. They were called upon to stem political and labor unrest within the United States. Under Commandant Jacob Zeilin's tenure, Marine customs and traditions took shape: the Corps adopted the Eagle, Globe, and Anchor, Marine Corps emblem on 19 November 1868. It was during this time that "The Marines' Hymn" was first heard. Around 1883, the Marines adopted their current motto "''Semper fidelis''" (''Always Faithful''). John Philip Sousa, the musician and composer, enlisted as a Marine apprentice at age 13, serving from 1867 until 1872, and again from 1880 to 1892 as the leader of theWorld War I
DuringWorld War II
InKorean War
The Korean War (1950–1953) saw the hastily formed 1st Provisional Marine Brigade, Provisional Marine Brigade holding the defensive line at the Battle of Pusan Perimeter, Pusan Perimeter. To execute a flanking maneuver, General Douglas MacArthur called on United Nations forces, including U.S. marines, to make an amphibious landing at Battle of Inchon, Inchon. The successful landing resulted in the collapse of North Korean lines and the pursuit of North Korean forces north near the Yalu River until the entrance of the People's Republic of China into the war. Chinese troops surrounded, surprised, and overwhelmed the overextended and outnumbered American forces. The U.S. Army's X Corps, which included the 1st Marine Division (United States), 1st Marine Division and the Army's 7th Infantry Division regrouped and inflicted heavy casualties during their fighting withdrawal to the coast, known as the Battle of Chosin Reservoir. The fighting calmed after the Battle of the Chosin Reservoir, but late in March 1953, the relative quiet of the war was broken when the People's Liberation Army launched a massive offensive on three outposts manned by the 5th Marine Regiment. These outposts were codenamed "Reno", "Vegas", and "Carson". The campaign was collectively known as the Nevada Cities Campaign. There was brutal fighting on Reno hill, which was eventually captured by the Chinese. Although Reno was lost, the 5th Marines held both Vegas and Carson through the rest of the campaign. In this one campaign, the Marines suffered approximately 1,000 casualties and might have suffered much more without the U.S. Army's Task Force Faith. Marines would continue a battle of attrition around the 38th parallel north, 38th Parallel until the Korean Armistice Agreement, 1953 armistice. During the war, the Corps expanded from 75,000 regulars to a force of 261,000 marines, mostly reservists; 30,544 marines were killed or wounded during the war, and 42 were awarded the Medal of Honor.Vietnam War
The Marine Corps served in the Vietnam War, taking part in such battles as the Battle of Huế, Battle of Hue and the Battle of Khe Sanh in 1968. Individuals from the USMC generally operated in the Northern I Corps Regions of South Vietnam. While there, they were constantly engaged in a guerrilla war against the Viet Cong, along with an intermittent conventional war against the People's Army of Vietnam, North Vietnamese Army, this made the Marine Corps known throughout Vietnam and gained a frightening reputation from the Viet Cong. Portions of the Corps were responsible for the less-known Combined Action Program that implemented unconventional techniques for counter-insurgency and worked as military advisers to the Republic of Vietnam Marine Division, Republic of Vietnam Marine Corps. Marines were withdrawn in 1971 and returned briefly in 1975 to evacuate Ho Chi Minh City, Saigon and attempt a rescue of the crew of the Mayaguez incident, SS ''Mayaguez''. Vietnam was the longest war up to that time for the Marines; by its end, 13,091 had been killed in action,Official Navy figures number the marine deaths at 13,091. This source provides a number of 14,837. 51,392 had been wounded, and 57 Medals of Honor had been awarded. Because of policies concerning rotation, more marines were deployed for service during Vietnam than World War II. While recovering from Vietnam, the Corps hit a detrimental low point in its service history caused by court-martial, courts-martial and non-judicial punishments related partially to increased desertion, unauthorized absences and desertions during the war. Overhaul of the Corps began in the late 1970s, discharging the most delinquent, and once the quality of new recruits improved, the Corps focused on reforming the non-commissioned officer Corps, a vital functioning part of its forces.Interim: Vietnam War to the War on Terror
After the Vietnam War, the U.S. marines resumed their expeditionary role, participating in the failed 1980 Iran hostage crisis, Iran hostage rescue attempt Operation Eagle Claw, the United States invasion of Grenada, Operation Urgent Fury and the United States invasion of Panama, Operation Just Cause. On 23 October 1983, the Marine barracks 1983 Beirut barracks bombings, in Beirut was bombed, causing the highest peacetime losses to the Corps in its history (220 marines and 21 other service members were killed) and leading to the American withdrawal from Lebanon. In 1990, marines of the Operation Sharp Edge, Joint Task Force Sharp Edge saved thousands of lives by evacuating British, French and American nationals from the violence of the First Liberian Civil War, Liberian Civil War. During the Gulf War, Persian Gulf War of 1990 to 1991, Marine task forces formed for Operation Desert Shield and later liberated Kuwait, along with Coalition forces, in Operation Desert Storm. Marines participated in combat operations in Somalia (1992–1995) during Operations Unified Task Force, Restore Hope, Restore Hope II, and Operation United Shield, United Shield to provide humanitarian relief. In 1997, marines took part in Operation Silver Wake, the evacuation of American citizens from the U.S. Embassy in Tirana, Albania.Global War on Terrorism
Following the September 11 attacks, attacks on 11 September 2001, President George W. Bush announced the War on terror, Global War on Terrorism. The stated objective of the Global War on Terror is "the defeat of Al-Qaeda, other terrorist groups and any nation that supports or harbors terrorists". Since then, the Marine Corps, alongside the other military services, has engaged in global operations around the world in support of that mission. In spring 2009, President Barack Obama's goal of reducing spending in the Defense Department was led by Secretary Robert Gates in a series of budget cuts that did not significantly change the Corps's budget and programs, cutting only the Lockheed Martin VH-71 Kestrel, VH-71 Kestrel and resetting the VXX program. However, the National Commission on Fiscal Responsibility and Reform singled the Corps out for the brunt of a series of recommended cuts in late 2010. In light of United States budget sequestration in 2013, budget sequestration in 2013, General James F. Amos, James Amos set a goal of a force of 174,000 Marines. He testified that this was the minimum number that would allow for an effective response to even a single contingency operation, but it would reduce the peacetime ratio of time at home bases to time deployed down to a historical low level.Afghanistan Campaign
Marines and other American forces began staging in Pakistan and Uzbekistan on the border of Afghanistan as early as October 2001 in preparation for War in Afghanistan (2001–2021), Operation Enduring Freedom. The 15th Marine Expeditionary Unit, 15th and 26th Marine Expeditionary Units were some of the first conventional forces into Afghanistan in support of Operation Enduring Freedom in November 2001. After that, Marine battalions and squadrons rotated through, engaging Taliban and Al-Qaeda forces. Marines of the 24th Marine Expeditionary Unit flooded into the Taliban-held town of Battle of Garmsir, Garmsir in Helmand province campaign, Helmand Province on 29 April 2008, in the first major American operation in the region in years. In June 2009, 7,000 marines with the 2nd Marine Expeditionary Brigade (United States), 2nd Marine Expeditionary Brigade (2nd MEB) deployed to Afghanistan in an effort to improve security and began Operation Strike of the Sword the next month. In February 2010, the 2nd MEB launched the largest offensive of the Afghan Campaign since 2001, the Operation Moshtarak, Battle of Marjah, to clear the Taliban from their key stronghold in Helmand Province. After Marjah, marines progressed north up the Helmand River and cleared the towns of Kajahki and Sangin. Marines remained in Helmand Province until 2014.Iraq Campaign
U.S. Marines served in the Iraq War, along with its sister services. The I Marine Expeditionary Force, along with the U.S. Army's 3rd Infantry Division (United States), 3rd Infantry Division, spearheaded the 2003 invasion of Iraq. The Marines left Iraq in the summer of 2003 but returned in the beginning of 2004. They were given Multi-National Force West, responsibility for the Anbar campaign (2003–2011), Al Anbar Province, the large desert region to the west of Baghdad. During this occupation, the Marines lead assaults on the city of Fallujah in April (First Battle of Fallujah, Operation Vigilant Resolve) and November 2004 (Second Battle of Fallujah, Operation Phantom Fury) and saw intense fighting in such places as Ramadi, Al-Qa'im (town), Al-Qa'im and Hit, Iraq, Hīt. The service's time in Iraq courted controversy with events such as the Haditha massacre, Haditha killings and the Hamdania incident. The Sons of Iraq, Anbar Awakening and Iraq War troop surge of 2007, 2007 surge reduced levels of violence. The Marine Corps officially ended its role in Iraq on 23 January 2010 when it handed over responsibility for Al Anbar Province to the U.S. Army. Marines American-led intervention in Iraq (2014–present), returned to Iraq in the summer of 2014 in response to growing violence there.Operations in Africa
Throughout the Global War on Terrorism, the U.S. Marines have supported operations in Africa to counter Islamic extremism and piracy in the Red Sea. In late 2002, Combined Joint Task Force – Horn of Africa was stood up at Camp Lemonnier, Djibouti to provide regional security. Despite transferring overall command to the Navy in 2006, the Marines continued to Operation Enduring Freedom – Horn of Africa, operate in the Horn of Africa into 2007.Organization
Department of the Navy
The United States Department of the Navy, Department of the Navy, led by the Secretary of the Navy, is a military department of the cabinet-level U.S. Department of Defense that oversees the Marine Corps and the Navy. The most senior Marine officer is the Commandant of the Marine Corps, Commandant (unless a Marine officer is the Chairman of the Joint Chiefs of Staff, Chairman of the Joint Chiefs or Vice Chairman of the Joint Chiefs of Staff, Vice Chairman of the Joint Chiefs), responsible to the Secretary of the Navy for organizing, recruiting, training, and equipping the Marine Corps so that its forces are ready for deployment under the operational command of the Unified combatant command, combatant commanders. The Marine Corps is organized into four principal subdivisions: Headquarters Marine Corps (HQMC), the Operating Forces, the Supporting Establishment, and the United States Marine Corps Reserve, Marine Forces Reserve (MARFORRES or USMCR).Headquarters Marine Corps
Headquarters Marine Corps (HQMC) consists of the Commandant of the Marine Corps, the Assistant Commandant of the Marine Corps, the Director Marine Corps Staff, the several Deputy Commandants, the Sergeant Major of the Marine Corps, and various special staff officers and Marine Corps agency heads that report directly to either the Commandant or Assistant Commandant. HQMC is supported by the Headquarters and Service Battalion, USMC providing administrative, supply, logistics, training, and services support to the Commandant and his staff.Operating Forces
The Operating Forces are divided into three categories: Marine Corps Forces (MARFOR) assigned to unified combatant commands, viz., theMarine Air-Ground Task Force
The basic framework for deployable Marine units is the Marine Air-Ground Task Force (MAGTF), a flexible structure of varying size. A MAGTF integrates a ground combat element (GCE), an aviation combat element (ACE), and a logistics combat element (LCE) under a common command element (CE), capable of operating independently or as part of a larger coalition. The MAGTF structure reflects a strong preference in the Corps towards self-sufficiency and a commitment toSupporting Establishment
The Supporting Establishment includes the Marine Corps Combat Development Command, Combat Development Command, the Marine Corps Logistics Command, Logistics Command, the Marine Corps Systems Command, Systems Command, the Marine Corps Recruiting Command, Recruiting Command, the Marine Corps Installations Command, Installations Command, theMarine Corps bases and stations
The Marine Corps operates many major bases, 14 of which host operating forces, 7 support and training installations, as well as satellite facilities. Marine Corps bases are concentrated around the locations of the Marine Expeditionary Forces, though reserve units are scattered throughout the United States. The principal bases are Marine Corps Base Camp Pendleton, Camp Pendleton on the West Coast, home to I Marine Expeditionary Force; Marine Corps Base Camp Lejeune, Camp Lejeune on the East Coast, home to II Marine Expeditionary Force; and Marine Corps Base Camp Smedley D. Butler, Camp Butler in Okinawa Prefecture, Okinawa, Japan, home to III Marine Expeditionary Force. Other important bases include air stations, recruit depots, logistics bases, and training commands. Marine Corps Air Ground Combat Center Twentynine Palms in California is the Marine Corps's largest base and home to the Corps's most complex, combined-arms, live-fire training. Marine Corps Base Quantico in Virginia is home to Marine Corps Combat Development Command and nicknamed the "Crossroads of the Marine Corps". The Marine Corps maintains a significant presence in the National Capital Region (United States), National Capital Region, with Headquarters Marine Corps scattered amongst the Pentagon, Henderson Hall (Arlington, Virginia), Henderson Hall, Washington Navy Yard, and Marine Barracks, Washington, D.C. Additionally, Marines operate Detachment (military), detachments at many installations owned by other branches to better share resources, such as specialty schools. Marines are also present at and operate many forward bases during expeditionary operations.Marine Forces Reserve
Marine Forces Reserve (MARFORRES/USMCR) consists of the Force Headquarters Group, 4th Marine Division, 4th Marine Aircraft Wing, and the 4th Marine Logistics Group. The MARFORRES/USMCR is capable of forming a 4th Marine Expeditionary Force or reinforcing/augmenting active-duty forces.Special Operations
Marine Forces Special Operations Command (MARSOC) includes the Marine Raider Regiment, the Marine Raider Support Group, and the Marine Raider Training Center (MRTC). Both the Raider Regiment and the Raider Support Group consist of a headquarters company and three operations battalions. MRTC conducts screening, assessment, selection, training and development functions for MARSOC units. Marine Corps Special Operations Capable forces include: Air Naval Gunfire Liaison Company (ANGLICO), Air Naval Gunfire Liaison Companies, the Chemical Biological Incident Response Force, the United States Marine Corps Reconnaissance Battalions, Marine Division Reconnaissance Battalions, United States Marine Corps Force Reconnaissance, Force Reconnaissance Companies, Maritime Special Purpose Force, and United States Marine Corps Special Operations Capable Forces#Special Reaction Teams, Special Reaction Teams. Additionally, all deployed MEUs are certified as "Marine expeditionary unit (special operations capable), special operations capable", viz. "MEU(SOC)", however Special Operations Capable forces are not considered to be special operations forces. Although the notion of a Marine special operations forces contribution to the United States Special Operations Command (USSOCOM) was considered as early as the founding of USSOCOM in the 1980s, it was resisted by the Marine Corps. Commandant Paul X. Kelley expressed the belief that marines should only support marines and that the Corps should not fund a special operations capability that would not directly support Marine Corps operations. However, much of the resistance from within the Corps dissipated when Marine leaders watched the Corps' 15th and 26th MEU(SOC)s "sit on the sidelines" during the very early stages of Operation Enduring Freedom while other conventional units and special operations units from the Army, Navy, and Air Force actively engaged in operations in Afghanistan. After a three-year development period, the Corps agreed in 2006 to supply a 2,500-strong unit, Marine Forces Special Operations Command, which would answer directly to USSOCOM.Personnel
Leadership
The Commandant of the Marine Corps is the highest-ranking officer of the Marine Corps, unless a marine is either the chairman or vice chairman of the Joint Chiefs of Staff. The commandant has the Title 10 of the United States Code, U.S. Code Title 10 responsibility to staff, train, and equip the Marine Corps and has no command authority. The commandant is a member of the Joint Chiefs of Staff and reports to the Secretary of the Navy. The Assistant Commandant of the Marine Corps acts as the chief deputy to the commandant. The Sergeant Major of the Marine Corps is the senior enlisted marine and acts as an adviser to the commandant. Headquarters Marine Corps comprises the rest of the commandant's counsel and staff (military), staff, with deputy commandants that oversee various aspects of the Corps assets and capabilities. The current and 38th Commandant is David H. Berger, David Berger, who assumed the position on 11 July 2019. The 36th and current Assistant Commandant is Eric Smith (general), Eric M. Smith, while the 19th and current Sergeant Major is Troy E. Black.Women
Women have served in the United States Marine Corps since 1918. The first woman to have enlisted was Opha May Johnson (1878–1955). In January 2017, three women joined an infantry battalion at Camp Lejeune. Women had not served as infantry marines prior to this. In 2017, the Marines released a recruitment advertisement that focused on women for the first time. , female Marines make up 7.8% of the personnel. In December 2020, the Marine Corps began a trial program to have females integrated into the training companies at their Marine Corps Recruit Depot San Diego, recruit depot in San Diego as Congress has mandated an end to the male-only program there. For the 60 female recruits, scheduled to begin training in San Diego in February 2021, the Corps will transfer female drill instructors from their Marine Corps Recruit Depot Parris Island, recruit depot in Parris Island, which already has a Mixed-sex education, coed program. Fifty-three of these recruits successfully graduated from boot camp in April 2021 and became marines.Minorities
In 1776 and 1777, a dozen African American marines served in the American Revolutionary War, but from 1798 to 1942, the Marine Corps followed a racially discriminatory policy of denying African Americans the opportunity to serve. The Marine Corps has a history of being last of the services to recruit African Americans, and its own history page acknowledges that it was a presidential order that "forced the Corps, despite objections from its leadership, to begin recruiting African American Marines in 1942..It accepted them as recruits into segregated all-black units. For the next few decades, the incorporation of black troops was not widely accepted within the Corps, nor was Desegregation in the United States, desegregation smoothly or quickly achieved. The integration of non-white Marine Corps personnel proceeded in stages from segregated battalions in 1942, to unified training in 1949, and finally full integration in 1960. Today the Marine Corps is a desegregated force, made up of marines of all races working and fighting alongside each other. As of 2020, African Americans are currently underrepresented in the Marine Corps as compared to their overall percentage of the U.S. population. Concurrently, the Marine Corps is the only service where Hispanics are overrepresented per the same metric.Rank structure
As in the rest of the United States Armed Forces (excluding the Air Force and Space Force, which do not currently appoint warrant officers), Marine Corps military rank, ranks fall into one of three categories: officer (armed forces), commissioned officer, Warrant officer (United States), warrant officer, and enlisted, in decreasing order of authority. To standardize compensation, each rank is assigned a pay grade.Commissioned officers
Commissioned officers are distinguished from other officers by their Commission (document), commission, which is the formal written authority, issued in the name of the President of the United States, that confers the rank and authority of a Marine officer. Commissioned officers carry the "special trust and confidence" of the President of the United States. Marine Corps commissioned officers are promoted based on an "up or out" system in accordance with the Defense Officer Personnel Management Act of 1980.Warrant officers
Warrant officers are primarily formerly enlisted experts in a specific specialized field and provide leadership generally only within that speciality.Enlisted
Enlisted marines in the pay grades E-1 to E-3 make up the bulk of the Corps's ranks. Although they do not technically hold leadership ranks, the Corps's ethos stresses leadership among all marines, and junior marines are often assigned responsibility normally reserved for superiors. Those in the pay grades of E-4 and E-5 are non-commissioned officers (NCOs). They primarily supervise junior Marines and act as a vital link with the higher command structure, ensuring that orders are carried out correctly. Marines E-6 and higher are staff non-commissioned officers (SNCOs), charged with supervising NCOs and acting as enlisted advisers to the command. The E-8 and E-9 levels have two and three ranks per pay grade, respectively, each with different responsibilities. The first sergeant and sergeant major ranks are command-oriented, serving as the senior enlisted marines in a unit, charged to assist the commanding officer in matters of discipline, administration, and the morale and welfare of the unit. Master sergeants and master gunnery sergeants provide technical leadership as occupational specialists in their specific MOS. The Sergeant Major of the Marine Corps also E-9, is a billet conferred on the senior enlisted marine of the entire Marine Corps, personally selected by the commandant. It is possible for an enlisted marine to hold a position senior to Sergeant Major of the Marine Corps which was the case from 2011 to 2015 with the appointment of Sergeant Major Bryan B. Battaglia to the billet of Senior Enlisted Advisor to the Chairman, who is the most senior enlisted member of the United States military, serving in the Joint Chiefs of Staff.Military Occupational Specialty
The Military Occupational Specialty (MOS) is a system of job classification. Using a four digit code, it designates what field and specific occupation a Marine performs. Segregated between officer and enlisted, the MOS determines the staffing of a unit. Some MOSs change with rank to reflect supervisory positions; others are secondary and represent a temporary assignment outside of a Marine's normal duties or special skill.Initial training
Every year, over 2,000 new Marine officers are commissioned, and 38,000 recruits are accepted and trained. All new marines, enlisted or officer, are military recruitment, recruited by the Marine Corps Recruiting Command. Commissioned officers are commissioned mainly through one of three sources: Naval Reserve Officer Training Corps, Officer Candidates School (United States Marine Corps), Officer Candidates School, or the United States Naval Academy. Following commissioning, all Marine commissioned officers, regardless of accession route or further training requirements, attend The Basic School at Marine Corps Base Quantico. At The Basic School, second lieutenants, warrant officers, and selected foreign officers learn the art of infantry andUniforms
The Marine Corps has the most stable and most recognizable uniforms in the American military; the Dress Blues dates back to the early 19th century and the service uniform to the early 20th century. Only a handful of skills (parachutist, air crew, explosive ordnance disposal, etc.) warrant Badges of the United States Marine Corps, distinguishing badges, and rank insignia is not worn on uniform headgear (with the exception of an officer's garrison service cover). Marines have four main uniforms: dress, service, utility, and physical training. These uniforms have a few minor but very distinct variations from enlisted personnel to commissioned and non-commissioned officers. The Marine Corps Full dress uniform, dress uniform is the most elaborate, worn for formal or ceremonial occasions. There are four different forms of the dress uniform. The variations of the dress uniforms are known as "Alphas", "Bravos", "Charlies", or "Deltas". The most common being the "Blue Dress Alphas or Bravos", called "Dress Blues" or simply "Blues". It is most often seen in recruiting advertisements and is equivalent to black tie. There is a "Blue-White" Dress for summer, and Evening Dress for formal (white tie) occasions, which are reserved for SNCO's and officers. Versions with a khaki shirt in lieu of the coat (Blue Dress Charlie/Delta) are worn as a daily working uniform by Marine recruiters and NROTC staff. The service uniform was once the prescribed daily work attire in garrison; however, it has been largely superseded in this role by the utility uniform. Consisting of olive green and khaki colors. It is roughly equivalent in function and composition to a suit (clothing), business suit. The utility uniform, currently the Marine Corps Combat Utility Uniform, is a camouflage uniform intended for wear in the field or for dirty work in garrison, though it has been standardized for regular duty. It is rendered in MARPAT pixelated camouflage that breaks up the wearer's shape. In garrison, the woodland and desert uniforms are worn depending on the marine's duty station. Marines consider the utilities a working uniform and do not permit their wear off-base, except in transit to and from their place of duty and in the event of an emergency.Culture
Official traditions and customs
As in any military organization, the official and unofficial traditions of the Marine Corps serve to reinforce camaraderie and set the service apart from others. The Corps's embrace of its rich culture and history is cited as a reason for its high ''esprit de corps''. An important part of the Marine Corps culture is the traditional seafaring Glossary of nautical terms, naval terminology derived from its history with the Navy. "Marines" are not "soldiers" or "sailors". The ''Marine Corps emblem'' is the Eagle, Globe, and Anchor, sometimes abbreviated "EGA", adopted in 1868. The Marine Corps seal includes the emblem, also is found on the flag of the United States Marine Corps, and establishes scarlet and gold as the official colors. The Marine motto ''Semper Fidelis'' means ''Always Faithful'' in Latin, often appearing as ''Semper Fi''. The ''Marines' Hymn'' dates back to the 19th century and is the oldest official song in the United States armed forces. ''Semper Fi'' is also the name of the Semper Fidelis (march), official march of the Corps, composed by John Philip Sousa. The mottos ''"Fortitudine"'' (With Fortitude); ''By Sea and by Land'', a translation of the Royal Marines' ''Per Mare, Per Terram''; and ''To the Shores of Tripoli'' were used until 1868. Two styles of swords are worn by marines: the officers' Mameluke Sword, similar to the Persian shamshir presented to Lt. Presley O'Bannon after the Battle of Derna, and the United States Marine Corps noncommissioned officer's sword, Marine NCO sword. The United States Marine Corps birthday ball, Marine Corps Birthday is celebrated every year on 10 November in a cake-cutting ceremony where the first slice of cake is given to the oldest marine present, who in turn hands it off to the youngest marine present. The celebration includes a reading of Commandant John A. Lejeune, Lejeune's Birthday Message. Close Order Drill is heavily emphasized early on in a marine's initial training, incorporated into most formal events, and is used to teach discipline by instilling habits of precision and automatic response to orders, increase the confidence of junior officers and noncommissioned officers through the exercise of command and give marines an opportunity to handle individual weapons.Unofficial traditions and customs
Marines have several generic nicknames: * ''Devil Dog:'' German soldiers during the First World War said that at Battle of Belleau Wood, Belleau Wood the marines were so vicious that the German infantrymen called them Teufel Hunden – 'devil dogs'. * ''Gyrene:'' commonly used between fellow marines. * ''Leatherneck:'' refers to a leather collar formerly part of the Marine uniform during the Revolutionary War period. * ''Jarhead'' has several oft-disputed explanations. Some other unofficial traditions include mottos and exclamations: * ''Oorah'' is common among marines, being similar in function and purpose to the Army, Air Force, and Space Force's hooah and the Navy's hooyah cries. Many possible Etymology, etymologies have been offered for the term. * ''Semper fidelis, Semper Fi'' is a common greeting among serving and veteran marines. * ''Improvise, Adapt and Overcome'' has become an adopted mantra in many units. The Marines have historically had issues with extremism in their ranks, particularly White supremacy. In 1976 the Camp Pendleton Chapter of the Ku Klux Klan had over 100 members and was headed by an active duty marine. In 1986, a number of marines were implicated in the theft of weapons for the White Patriot Party. The USMC, along with the rest of the military, has since made a serious effort to address extremism in the ranks.Veteran marines
The Corps encourages the idea that "marine" is an earned title, and most Marine Corps personnel take to heart the phrase, "Once a marine, Always a marine". They reject the term "ex-marine" in most circumstances. There are no regulations concerning the address of persons who have left active service, so a number of customary terms have come into common use.Martial arts program
In 2001, the Marine Corps initiated an internally designed martial arts program, called Marine Corps Martial Arts Program (MCMAP). Because of an expectation that urban and police-type peacekeeping missions would become more common in the 21st century, placing marines in even closer contact with unarmed civilians, MCMAP was implemented to provide marines with a larger and more versatile set of less-than-lethal options for controlling hostile, unarmed individuals. It is a stated aim of the program to instill and maintain the "Warrior Ethos" within marines.Yi, Capt. Jamison, USMC. "MCMAP and the Warrior Ethos", ''Military Review'', November–December 2004. The MCMAP is an eclectic mix of different styles of martial arts melded together. MCMAP consists of punches and kicks from Taekwondo and Karate, opponent weight transfer from Jujutsu, Jujitsu, ground grappling involving joint locking techniques and chokehold, chokes from Brazilian jiu-jitsu, and a mix of knife and baton/stick fighting derived from Arnis, Eskrima, and elbow strikes and kick boxing from Muay Thai. Marines begin MCMAP training in boot camp, where they will earn the first of five available Marine Corps Martial Arts Program#Structure and belt system, belts. The belts begin at tan and progress to black and are worn with standard utility uniforms.Equipment
As of 2013, the typical infantry rifleman carries $14,000 worth of gear (excluding night vision device, night-vision goggles), compared to $2,500 a decade earlier. The number of pieces of equipment (everything from radios to trucks) in a typical infantry battalion has also increased, from 3,400 pieces of gear in 2001 to 8,500 in 2013.Infantry weapons
The basic infantry weapon of the Marine Corps has been the M16 rifle, M16A4 service rifle. Most non-infantry marines have been equipped with the M4 carbine, M4 Carbine or Colt 9mm SMG. The standard Sidearm (weapon), side arm is the Beretta M9, M9A1 pistol. The Colt M1911 pistol, M1911 is also being put back into service as the MEU(SOC) pistol, M45A1 Close Quarter Battle Pistol (CQBP) in small numbers. Suppressive fire is provided by the M27 Infantry Automatic Rifle, M27 IAR, M249 light machine gun, M249 SAW, and M240 machine gun, M240 machine guns, at the squad and company levels respectively. In 2018, the M27 IAR was selected to be the standard issue rifle for the all infantry squads. In 2021, the Marine Corps committed to fielding Silencer (firearms), suppressors to all its infantry units, making it the first branch of the U.S. military to adopt them for widespread use. Indirect fire is provided by the M203 grenade launcher and the Milkor MGL, M32 grenade launcher in fireteams, M224 mortar, M224 60 mm mortar in companies, and M252 mortar, M252 81 mm mortar in battalions. The M2 Browning, M2 .50 caliber heavy machine gun and Mk 19 grenade launcher, MK19 automatic grenade launcher (40 mm) are available for use by dismounted infantry, though they are more commonly vehicle-mounted. Precision firepower is provided by the M40 rifle, M40 series and the Barrett M82, Barrett M107, while Designated marksman, designated marksmen use the United States Marine Corps Designated Marksman Rifle, DMR (being replaced by the M39 Enhanced Marksman Rifle, M39 EMR), and the United States Marine Corps Squad Advanced Marksman Rifle, SAM-R. The Marine Corps utilizes a variety of direct-fire rockets and missiles to provide infantry with an offensive and defensive anti-armor capability. The Mk 153 Shoulder-Launched Multipurpose Assault Weapon, SMAW and AT4 are unguided rockets that can destroy armor and fixed defenses (e.g., bunkers) at ranges up to 500 meters. The smaller and lighter M72 LAW can destroy targets at ranges up to 200 meters. The FGM-172 SRAW, Predator SRAW, FGM-148 Javelin and BGM-71 TOW are anti-tank guided missiles. The Javelin can utilize top-attack profiles to avoid heavy frontal armor. The Predator is a short-range fire-and-forget weapon; the Javelin and TOW are heavier missiles effective past 2,000 meters that give infantry an offensive capability against armor.Ground vehicles
The Corps operates the same Humvee, HMMWV as does the Army, which is in the process of being replaced by the Joint Light Tactical Vehicle (JLTV). However, for its specific needs, the Corps uses a number of unique vehicles. The LAV-25 is a dedicated wheeled armored personnel carrier, similar to the Army's Stryker vehicle, used to provide strategic mobility. Amphibious capability is provided by the Assault Amphibious Vehicle, AAV-7A1 Assault Amphibious Vehicle, an armored tracked vehicle that doubles as an Armoured personnel carrier, armored personnel carrier, due to be replaced by the Amphibious Combat Vehicle, a faster vehicle with superior armor and weaponry. The threat of land mines and improvised explosive devices in Iraq and Afghanistan has seen the Corps begin purchasing heavy armored vehicles that can better withstand the effects of these weapons as part of the MRAP, Mine Resistant Ambush Protected vehicle program. The Marines also operate the M777 howitzer, M777 155 mm howitzer and the M142 HIMARS, High Mobility Artillery Rocket System (HIMARS), a truck-mounted rocket artillery system. Both are capable of firing guided munitions. In 2020, the Marine Corps retired its M1 Abrams, M1A1 Abrams tanks and eliminated all of its tank units. General David Berger explained the decision describing the long-serving Marine weapons system as "operationally unsuitable for our highest-priority challenges." The move leaves the Army as the sole operator of American tanks.Aircraft
The Organic unit, organic aviation capability of the Marine Corps is essential to its amphibious mission. The Corps operates both helicopter, rotary-wing and fixed-wing aircraft mainly to provide Assault Support and close air support to its ground forces. Other aircraft types are used in a variety of support and special-purpose roles. The light transport and attack capabilities are provided by the Bell UH-1Y Venom and Bell AH-1Z Viper. Medium-lift squadrons utilize the Bell-Boeing V-22 Osprey, MV-22 Osprey tiltrotor. Heavy-lift squadrons are equipped with the Sikorsky CH-53E Super Stallion, CH-53E Super Stallion helicopter, which are being replaced with the upgraded Sikorsky CH-53K, CH-53K. Marine attack squadrons fly the McDonnell Douglas AV-8B Harrier II, AV-8B Harrier II; while the fighter/attack mission is handled by the single-seat and dual-seat versions of the McDonnell Douglas F/A-18 Hornet, F/A-18 Hornet strike-fighter aircraft. The AV-8B is a V/STOL aircraft that can operate from amphibious assault ships, land air bases and short, expeditionary airfields, while the F/A-18 can only be flown from land or aircraft carriers. Both are slated to be replaced by 340 of the STOVL B version of the Lockheed Martin F-35 Lightning II, F-35 Lightning II and 80 of the carrier F-35C versions for deployment with NavyRelationship with other services
In general, the Marine Corps shares many resources with the other branches of theUnited States Navy
The Marine Corps's counterpart under the Department of the Navy is the United States Navy. As a result, the Navy and Marine Corps have a close relationship, more so than with other branches of the military. White paper, Whitepapers and promotional literature have commonly used the phrase "Navy-Marine Corps Team", or refer to "the Naval Service". Both the Chief of Naval Operations (CNO) and Commandant of the Marine Corps report directly to the Secretary of the Navy. Operationally, the Marine Corps provides theUnited States Army
The Marine Corps capabilities overlap with those of the United States Army, historically creating competition for funding and missions. The competition dates back to the founding of the Continental Marines, when General George Washington refused to allow the initial Marine battalions to be drawn from among his Continental Army. In the aftermath of World War II, Army leadership made efforts to restructure the American defense establishment including the dissolution of the Marine Corps and the folding of its capabilities into the other services. Leading this movement were such prominent Army officers as General Dwight D. Eisenhower and Chief of Staff of the United States Army, Army Chief of Staff George C. Marshall. The Goldwater-Nichols Act significantly reshaped the services roles and relationships with each other, enforcing more joint decision making. Department of Defense Directive 5100.01 tasks both the Army and Marine Corps with expeditionary and amphibious operations. With most of the 2000s spent in operations in Afghanistan and Iraq, Secretary of Defense Robert Gates voiced concerns that the Marine Corps are becoming a "second Army". Since these comments, the Marine Corps has shed its main battle tanks, reduced its size, and focused more on operations in littoral areas where the Army is not explicitly tasked to operate. The Army maintains much larger and diverse combat arms, special operations, and logistics forces. The Army has much lighter and expeditionary forces in its infantry and airborne infantry brigade combat teams. The Army also maintains heavier and more logistically taxing armored brigade combat teams. The Marine Corps, in comparison, maintains forces between these two extremes of mobility and protection. The Marine Corps organizes much smaller deployable units with integrated aviation support. The Marine Corps was historically hesitant to provide forces to U.S. Special Operations Command, instead making specialty units available to its division commanders. The Army has maintained Special Forces, Rangers, civil affairs, psychological operations, special operations aviation, and special missions units for decades. In 2003, the Marine Corps created the present-day successors to the Marine Raiders and provided them to United States Special Operations Command, Special Operations Command starting with the establishment of Det One, MCSOCOM Detachment One. The modern Marine Raider training pipeline was based on input from U.S. Army Ranger and Special Forces units. Culturally, marines and soldiers share most of the common U.S. military slang and terminology, but the Corps utilizes a large number of naval terms and traditions incompatible with Army lifestyle, as well as their own List of United States Marine Corps acronyms and expressions, unique vernacular. As the Army Reserve and Army National Guard is much larger than the Marine Corps's Reserve, many more former active duty marines continue their service in the Army's reserve components. The Army does not require transfers from the Marines, Air Force Security Forces, or special operations of any branch to attend Army Basic Combat Training. Due to the requirement that all inter-service transfers attend Marine Corps Recruit Training, very few former soldiers serve in the Marine Corps.United States Air Force
While some of United States Marine Corps Aviation, Marine Corps Aviation assets ultimately derive from the Navy, a large amount of support is drawn from the United States Air Force. The Marine Corps makes extensive use of the USAF Air Mobility Command to airlift marines and equipment, along with utilizing close air support from the Air Force. The Air Force may also attach Tactical Air Control Party units to conventional Marine ground forces to provide coordination for close air support. The Air Force traditionally provides the Joint Force Air Component Commander (JFACC) who controls "sorties for air defense, and long range interdiction and reconnaissance" while the MAGTF commander retains control of the Marines' organic aviation assets, however Marine Aviation missions not directly in the support of the MAGTF will be typically controlled by the JFACC.United States Coast Guard
The Marine Corps shares a sphere of operation with units of the United States Coast Guard, including operation of the Joint Maritime Training Center (JMTC) (previously known as the Special Missions Training Center (SMTC)), a joint Coast Guard, Navy, and Marine Corps training facility located on the Marine Corps Base Camp Lejeune in Camp Lejeune, North Carolina.Budget
According to the Department of the Navy (from whence the Marine Corps receives its funding), for FY 2019, the Marine Corps received $43.2B in funding.See also
