United States military seniority is the method by which the United States Armed Forces determines precedence among commissioned officers, in particular those who hold the same rank. Seniority is used to determine assignments, tactical commands, promotions and general courtesy. To a lesser extent, historical seniority is used to recognize status of honor given to early United States military leaders such as inaugural holders of certain ranks or those officers who served as leadership during major wars and armed conflicts.
The modern-day seniority system of the United States commissioned officer corps operates on two different levels. For officers of different ranks, seniority is simply determined by who holds the highest rank. For instance, Army colonel is senior to captain and captain senior to lieutenant. Seniority extends across services as for instance major in the Army is senior to captain in the Air Force while commander in the United States Navy is senior to both. For officers in the same rank or paygrade, seniority is determined by the dates on which they assumed their ranks. [1] If officers of the same grade have the same date of rank, then seniority is determined in order by the officer's previous rank's date and so forth. [1] If all promotion dates of ranks are the same, seniority is then determined on order of: previous active duty grade relative seniority (if applicable), [1] total active commissioned service, [1] and finally, total federal commissioned service or date of appointment as a commissioned officer. [1] The secretaries of each service may establish further seniority rules if applicable. [1]
Whenever there are two or more officers in the same grade or rank, who are on duty in the same area, field command, or organization, and who are all eligible to command, the president may assign command to an officer, without regard to time-in-rank. [2]
A type of "positional seniority" exists for military officers who hold top leadership positions of the armed forces. For instance, the Chairman of the Joint Chiefs of Staff is considered the most senior officer of the entire United States military, even though it is possible that contemporaries of the same rank may have earlier dates of rank or longer time in service. Likewise, heads of various armed service branches are considered most senior within their service; unified commanders are also considered most senior in their respective regions yet not necessarily to each other.
The regular United States military hierarchy is as follows:
When compared to each other, seniority among the service chiefs is determined by date of when the officer assumed that particular office, from the following group:
The Commandant of the Coast Guard has seniority and precedence immediately after the service chiefs.
The officers in charge of the Unified Combatant Commands are considered "operational officers" while the standard military hierarchy is administrative. For instance, the Chief of Naval Operations, who would most likely be senior to a naval admiral in command of the United States Pacific Command, would not be able to issue direct orders to said commander since operational chain of command is separate from regular administrative military hierarchy. [3] Military seniority, within itself, would not be affected.
Tactical seniority, also known as "battlefield seniority", is the manner in which a senior officer in command of a given tactical situation is determined. For instance, within the United States Navy, groups of ships performing exercises together will have one ship designated as the tactical senior unit. The commander of said ship is the senior tactical officer and may in fact be junior in rank to the other officers of the tactical group. For multi-national exercises, such as the Sharem event in South Korea, ships of foreign nations are sometimes given tactical seniority and thus may issue routine movement orders to United States vessels. Actual combat would fall under the Task Force system, in which a United States admiral, with clear seniority, would take command over all vessels.
Groups of Army units, especially in active combat, may be placed under tactical command of any officer, regardless of rank seniority, for completion of a single mission. During World War II, the term "mixed unit" was commonly used to denote military formations created from several other smaller units, most often "on the spot", due to operational confusion and the need for a single battlefield commander to take authority over all units physically present. Army Air Force bomber groups operated on a similar principle, in that tactical command could pass to officers who were not necessarily the most senior present, given the specific needs of the mission or casualties during the mission itself.
Operational seniority refers to the ability to issue long range orders to U.S. forces, such as deployments, general orders, and other administrative matters. Operational seniority is never granted to non-U.S. officers and usually stems from such major offices as the Bureau of Naval Personnel or the Army Personnel Branch.
The only case where historical seniority has been legally established by the United States Congress is for the "super rank" of the armed forces of the United States General of the Armies. By clear precedent, the holders of this rank (three persons in all) are senior to all other officers of the United States military, past and present. By special Congressional edict, George Washington is considered the most senior officer of all time meaning he may never be lesser in seniority to any other military officer, although Washington technically shares the same rank with John Pershing and Ulysses S. Grant.
The office of general was discontinued after the Civil War, but revived in 1919 by the title of "General of the Armies of the United States" when General John J. Pershing was appointed to that office on 3 September 1919; accepted the appointment on 8 September 1919, was retired with that rank on 13 September 1924, and held it until his death on 15 July 1948. No other officer has occupied this office on active duty. General Pershing held the grade of General of the Armies of the United States under the provisions of the Act of U.S. Congress of 3 September 1919 (Public Law 45). Washington was posthumously appointed General of the Armies of the United States under s:Public Law 94-479. Under s:Order 31-3, the effective promotion date was on 4 July 1976. Congress specified that no officer of the United States Army should outrank Lieutenant General George Washington on the Army list. While promoted to a lieutenant general only a year before his death, he was the most senior officer and the only lieutenant general in the army. The same is true of Ulysses S. Grant, who was the second person to permanently hold this rank. (Winfield Scott was a brevet lieutenant general for his service in the Mexican–American War.) Washington was referred to as "commander in chief" of the Continental Army, a title that since the adoption of the Constitution has been reserved for the (civilian) President.
The five star officers of World War II are technically considered the most senior officers in U.S. history (with the exception of the two "super ranks" previously mentioned), yet are often considered historically junior to the military leaders of the 19th century, especially the inaugural holders of senior military ranks. Most historical seniority lists also omit three star officers, with some rare exceptions (such as Winfield Scott), and typically avoid comparing two star ranks and below, which are permanent ranks held by hundreds of officers over the past two centuries. In these cases, standard methods of seniority are used. Since 1981, the highest rank held by any officer in the U.S. armed forces is four stars, or a pay grade of "O-10". Modern-day admirals and generals are typically not considered in lists of historical seniority, except for extreme cases such as leaders of wars or other wide scale armed conflicts.
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry.
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.
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.
Commander is a common naval officer rank as well as a job title in many armies. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain.
The chairman of the Joint Chiefs of Staff (CJCS) is the presiding officer of the Joint Chiefs of Staff (JCS). The chairman is the highest-ranking and most senior military officer in the United States Armed Forces and the principal military advisor to the president, the National Security Council, the Homeland Security Council, and the secretary of defense. While the chairman of the Joint Chiefs of Staff outranks all other commissioned officers, the chairman is prohibited by law from having operational command authority over the armed forces; however, the chairman assists the president and the secretary of defense in exercising their command functions.
Chief Warrant officer is a senior warrant officer rank, used in many countries.
Fleet admiral is a five-star flag officer rank in the United States Navy whose rewards uniquely include active duty pay for life. Fleet admiral ranks immediately above admiral and is equivalent to General of the Army and General of the Air Force.
A flag officer is a commissioned officer in a nation's armed forces senior enough to be entitled to fly a flag to mark the position from which the officer exercises command.
General-in-chief has been a military rank or title in various armed forces around the world.
General of the Army is a five-star general officer rank in the United States Army. It is generally equivalent to the rank of Field Marshal in other countries. In the United States, a General of the Army ranks above generals and is equivalent to a fleet admiral and a general of the Air Force. The General of the Army insignia consisted of five 3⁄8-inch (9.5 mm) stars in a pentagonal pattern, with touching points. The insignia was paired with the gold and enameled United States coat of arms on service coat shoulder loops. The silver colored five-star metal insignia alone would be worn for use as a collar insignia of grade and on the garrison cap. Soft shoulder epaulets with five 7⁄16-inch (11 mm) stars in silver thread and gold-threaded United States coat of arms on green cloth were worn with shirts and sweaters.
Admiral is a four-star commissioned officer rank in the United States Navy, the United States Coast Guard, and the United States Public Health Service Commissioned Corps with the pay grade of O-10. Admiral ranks above vice admiral and below fleet admiral in the Navy; the Coast Guard and the Public Health Service do not have an established grade above admiral. Admiral is equivalent to the rank of general in the other uniformed services. The National Oceanic and Atmospheric Administration Commissioned Officer Corps has never had an officer hold the grade of admiral. However, 37 U.S.C. § 201 of the U.S. Code established the grade for the NOAA Corps, in case a position is created that merits the four-star grade.
In the United States military, a general is the most senior general-grade officer; it is the highest achievable commissioned officer rank that may be attained in the United States Armed Forces, with exception of the Navy and Coast Guard, which have the equivalent rank of admiral instead. The official and formal insignia of "general" is defined by its four stars.
Commodore was an early title and later a rank in the United States Navy, United States Coast Guard and the Confederate States Navy, and also has been a rank in the United States Public Health Service Commissioned Corps and the National Oceanic and Atmospheric Administration Commissioned Officer Corps and its ancestor organizations. For over two centuries, the designation has been given varying levels of authority and formality.
In the United States Armed Forces, a lieutenant general is a three-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
Military organization (AE) or military organisation (BE) is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. Formal military organization tends to use hierarchical forms.
A five-star rank is the highest military rank in many countries. The rank is that of the most senior operational military commanders, and within NATO's standard rank scale it is designated by the code OF-10. Not all armed forces have such a rank, and in those that do the actual insignia of the five-star ranks may not contain five stars. For example: the insignia for the French OF-10 rank maréchal de France contains seven stars; the insignia for the Portuguese marechal contains four gold stars. The stars used on the various Commonwealth of Nations rank insignias are sometimes colloquially referred to as pips, but in fact either are stars of the orders of the Garter, Thistle or Bath or are Eversleigh stars, depending on the wearer's original regiment or corps, and are used in combination with other heraldic items, such as batons, crowns, swords or maple leaves.
The Singapore Armed Forces (SAF) has five rank schemes for active and reservist personnel, with a sixth for the auxiliaries of the SAF Volunteer Corps. The SAF has a unique rank structure as an integrated force, ranks are the same in the Singapore Army, the Republic of Singapore Navy (RSN), the Republic of Singapore Air Force (RSAF), and the Digital and Intelligence Service (DIS).
A general officer is an officer of high military rank; in the uniformed services of the United States, general officers are commissioned officers above the field officer ranks, the highest of which is colonel in the Army, Marine Corps, Air Force, and Space Force and captain in the Navy, Coast Guard, Public Health Service Commissioned Corps (PHSCC), and National Oceanic and Atmospheric Administration Commissioned Corps (NOAACC).
The general officers of the Confederate States Army (CSA) were the senior military leaders of the Confederate States of America during the American Civil War of 1861–1865. They were often former officers from the United States Army before the Civil War, while others were given the rank based on merit or when necessity demanded. Most Confederate generals needed confirmation from the Confederate States Congress, much like prospective generals in the modern U.S. armed forces.
