A company is a military unit, typically consisting of 100–250 soldiers and usually commanded by a major or a captain. Most companies are made up of three to seven platoons, although the exact number may vary by country, unit type, and structure.
Military ranks are a system of hierarchical relationships within armed forces, police, intelligence agencies and other institutions organized along military lines. Responsibility for personnel, equipment and missions grow with each advancement. The military rank system defines dominance, authority and responsibility within a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command is an important component for organized collective action.
A platoon is a military unit typically composed of two to four squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 20–50 troops, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a commissioned officer. The platoon leader is usually a junior officer—a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
Sergeant is a rank in use by the armed forces of many countries. It is also a police rank in some police services. The alternative spelling, serjeant, is used in The Rifles and other units that draw their heritage from the British light infantry. Its origin is the Latin serviens, 'one who serves', through the Old French term serjant.
Corporal is a military rank in use by the armed forces of many countries. It is also a police rank in some police services. The rank is usually the lowest ranking non-commissioned officer. In some militaries, the rank of corporal nominally corresponds to commanding a section or squad of soldiers.
Gunnery sergeant (GySgt) is the seventh enlisted rank in the United States Marine Corps, above staff sergeant and below master sergeant and first sergeant, and is a senior non-commissioned officer (SNCO). It has a pay grade of E-7.
Force Reconnaissance (FORECON) are special operations capable forces companies unit of the United States Marine Corps and part of the Fleet Marine Force that provide gathering military intelligence to the command element of the Marine Air-Ground Task Force (MAGTF). Force Reconnaissance companies report to the Marine expeditionary force (MEF) and provide amphibious reconnaissance to support amphibious warfare operations, deep reconnaissance, direct action against important strategic or tactical goals, irregular warfare, ISTAR, long-range penetration, and special reconnaissance during large-scale operations.
The School of Infantry (SOI) is the second stage of initial military training for enlisted United States Marines after recruit training. The ITB now called IMC went from a 59 day course to 14 week course. Since the initial training pipeline is divided between coasts, Marines from areas east of the Mississippi River usually graduate from MCRD Parris Island and move on to SOI at SOI East, while those from the western half of the nation attend MCRD San Diego and move on to SOI West at the Camp San Onofre area of Camp Pendleton in California. Female Marines are trained at both SOI East and SOI West. The School of Infantry's training mission ensures "Every Marine is, first and foremost, a Rifleman". At SOI, Marines with the Military Occupational Specialty of infantry are trained at the Infantry Training Battalion (ITB), while all non-infantry Marines are trained in basic infantry and combat skills at the Marine Combat Training Battalion. SOI marks a transition in the professional training of entry-level students from basically trained Marines to combat-ready Marines.
The Basic School (TBS) is where all newly commissioned and appointed United States Marine Corps officers are taught the basics of being an "Officer of Marines." The Basic School is located in Stafford County, Virginia to the south-west of the Marine Corps Base Quantico complex. Each year, over 1,700 new officers are trained, representing such commissioning sources as the U.S. Naval Academy, Navy ROTC, Officer Candidates School, and newly appointed Marine Corps Warrant Officers, U.S. Merchant Marine Academy accession programs.
The United States Marine Corps Reconnaissance Battalions are the special operations capable forces assets of Marine air–ground task force (MAGTF) that provide division-level amphibious reconnaissance, counter reconnaissance, direct action, ground reconnaissance, irregular warfare, long-range penetration, maneuver warfare, and special reconnaissance to the Ground Combat Element within the United States Marine Corps (USMC). Division reconnaissance teams are employed to observe and report on enemy activity and other information of military significance in close operations. The Military Occupational Specialty code for Reconnaissance Marine is 0321.

The United States Marine Corps is organized within the Department of the Navy, which is led by the Secretary of the Navy (SECNAV). The most senior Marine commissioned officer is the Commandant of the Marine Corps, responsible for organizing, recruiting, training, and equipping the Marine Corps so that it is ready for operation under the command of the unified combatant commanders. The Marine Corps is organized into four principal subdivisions: Headquarters Marine Corps, the Operating Forces, the Supporting Establishment, and the Marine Forces Reserve.
In the United States Marine Corps, the ground combat element (GCE) is the land force of a Marine Air-Ground Task Force (MAGTF). It provides power projection and force for the MAGTF.

A headquarters and service company is a company-sized military unit, found at the battalion and regimental level in the U.S. Marine Corps. The U.S. Army equivalent unit is the headquarters and headquarters company.
All branches of the United States Armed Forces use the general term Enlisted Professional Military Education (EPME) to describe the formal system of education which each branch provides to its enlisted personnel. Each branch has its own system and sequence of courses, with the overall focus on leadership and management. Education generally increases in intensity and level of knowledge as individuals progress in rank and assume broader leadership roles. EPME is distinct from the technical training which service members receive for their Military Occupational Specialty (MOS), Air Force Specialty Code (AFSC), or Navy Rating.
