, the Bahamas. The role of the Marine Corps has expanded significantly since then; as the importance of its original naval mission declined with changing naval warfare doctrine and the professionalization of the naval service, the Corps adapted by focusing on formerly secondary missions ashore. The Advanced Base Doctrine of the early 20th century codified their combat duties ashore, outlining the use of marines in the seizure of bases and other duties on land to support naval campaigns.
Throughout the late 19th and 20th centuries, Marine detachments served aboard Navy cruisers, battleships and aircraft carriers. Marine detachments served in their traditional duties as a ship's landing force, manning the ship's weapons and providing shipboard security. Marine detachments were augmented by members of the ship's company for landing parties, such as in the First Sumatran expedition of 1832, and continuing in the Caribbean and Mexican campaigns of the early 20th centuries. Marines developed tactics and techniques of amphibious assault on defended coastlines in time for use in World War II. During World War II, marines continued to serve on capital ships. They often were assigned to man anti-aircraft batteries.

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, Marine aviation has always been focused on

, emphasizing the infantry combat abilities of every marine. All marines, regardless of military specialization, receive training as a rifleman; and all officers receive additional training as infantry platoon commanders. During World War II at the Battle of Wake Island, when all of the Marine aircraft were destroyed, pilots continued the fight as ground officers, leading supply clerks and cooks in a final defensive effort. Flexibility of execution is implemented via an emphasis on " commander's intent" as a guiding principle for carrying out orders, specifying the end state but leaving open the method of execution.

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

. 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.

, 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 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 ranks fall into one of three categories:

Commissioned officers
Commissioned officers are distinguished from other officers by their 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.

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

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.

Uniforms
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 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 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

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 naval terminology derived from its history with the Navy. "Marines" are not "soldiers" or "sailors".

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.

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.

While the Marine Corps has far fewer installations both in the U.S. and worldwide than the other branches, many Army posts, Naval stations, and Air Force bases have a Marine presence. They also cross-train with other countries.
United 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.

This new strategy charts a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent regional crises, man-made or natural, from occurring or reacting quickly should one occur to avoid negative impacts to the United States.
United 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

. 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

and provided them to Special Operations Command starting with the establishment of 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 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.
