Military ranks are a system of hierarchical relationships, within armed forces, police, intelligence agencies or other institutions organized along military lines. The military rank system defines dominance, authority, and responsibility in 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 constructs an important component for organized collective action.
Sergeant (Sgt) 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.
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services.
A master sergeant is the military rank for a senior non-commissioned officer in the armed forces of some countries.
Sergeant major is a senior non-commissioned rank or appointment in many militaries around the world.
Epaulette is a type of ornamental shoulder piece or decoration used as insignia of rank by armed forces and other organizations. Flexible metal epaulettes are referred to as shoulder scales.
The chart below shows the current enlisted rank insignia of the United States Army, with seniority, and pay grade, increasing from right to left. The enlisted ranks of corporal (E-4) and higher are considered non-commissioned officers (NCOs). The rank of specialist is also in pay grade E-4, but does not hold non-commissioned officer status; it is common that a soldier may never hold the rank of corporal, and instead be promoted from specialist to sergeant, attaining junior NCO status at that time.
Officer Cadet is a rank held by military cadets during their training to become commissioned officers. In the United Kingdom, the rank is also used by members of University Royal Naval Units, University Officer Training Corps and University Air Squadron; however, these are not trainee officers with many not choosing a career in the armed forces.
Listed in the table below are the insignia—emblems of authority—of the British Army. Badges for field officers were introduced in 1810 and the insignia was moved to the epaulettes in 1880. On ceremonial or parade uniforms these ranks continue to be worn on the epaulettes, either as cloth slides or as metal clips, although on the modern 'working dress' they are usually worn as a cloth slide on the chest. Although these insignia apply across the British Army there is variation in the precise design and colours used and it can take some time to become familiar with them all.
Modern Russian military ranks trace their roots to the Table of Ranks established by Peter the Great. Most of the rank names were borrowed from existing German/Prussian, French, English, Dutch, and Polish ranks upon the formation of the Russian regular army in the late 17th century.
Valley Forge Military Academy and College (VFMAC) is a private boarding school and military junior college in Wayne, Pennsylvania. It follows in the traditional military school format with army traditions. Though military in tradition and form, the high school portion of VFMAC, Valley Forge Military Academy, is a college-preparatory boarding institution specializing in student leadership.

Major (Maj) is a military rank which is used by both the British Army and Royal Marines. The rank is superior to captain and subordinate to lieutenant colonel. The insignia for a major is a crown. The equivalent rank in the Royal Navy is lieutenant commander, and squadron leader in the Royal Air Force.
In the United States Army, Marine Corps, Air Force and Space Force, major is a field officer above the rank of captain and below the rank of lieutenant colonel. It is equivalent to the naval rank of lieutenant commander in the other uniformed services. Although lieutenant commanders are considered junior officers by their services, the rank of major is that of a senior officer in the United States Army, the United States Marine Corps, and the United States Air Force.
In the United States Army, Marine Corps, Air Force and Space Force, lieutenant colonel is a field-grade officer rank, just above the rank of major and just below the rank of colonel. It is equivalent to the naval rank of commander in the other uniformed services.

In the uniformed services of the United States, captain is a commissioned-officer rank. In keeping with the traditions of the militaries of most nations, the rank varies between the services, being a senior rank in the naval services and a junior rank in the ground and air forces. Many fire departments and police departments in the United States also use the rank of captain as an officer in a specific unit.
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.
