The Legion of Merit (LOM) is a military award of the United States Armed Forces that is given for exceptionally meritorious conduct in the performance of outstanding services and achievements. The decoration is issued to members of the eight uniformed services of the United States as well as to military and political figures of foreign governments.
The United States has eight federal uniformed services that commission officers as defined by Title 10 and subsequently structured and organized by Titles 10, 14, 32, 33, and 42 of the U.S. Code.
The Defense Superior Service Medal (DSSM) is a military decoration of the United States Department of Defense, which is presented to United States Armed Forces service members who perform superior meritorious service in a position of significant responsibility.
The National Oceanic and Atmospheric Administration Commissioned Officer Corps is one of eight federal uniformed services of the United States, and operates under the National Oceanic and Atmospheric Administration (NOAA), a scientific agency overseen by the Department of Commerce. The NOAA Corps is made up of scientifically and technically trained officers. The NOAA Corps and the United States Public Health Service Commissioned Corps are the only U.S. uniformed services that consist only of commissioned officers, with no enlisted or warrant officer ranks. The NOAA Corps' primary mission is to monitor oceanic conditions, support major waterways, and monitor atmospheric conditions.
The several branches of the United States Armed Forces are represented by flags. Within the U.S. military, various flags fly on various occasions, and on various ships, bases, camps, and military academies.
The United States Merchant Marine Academy is a United States service academy in Kings Point, New York. It trains its midshipmen to serve as officers in the United States Merchant Marine, branches of the United States Armed Forces, and the transportation industry. Midshipmen are trained in marine engineering, navigation, ship's administration, maritime law, personnel management, international law, customs, and other subjects important to the task of running a large ship.
A maritime flag is a flag designated for use on ships, boats, and other watercraft. Naval flags are considered important at sea and the rules and regulations for the flying of flags are strictly enforced. The flag flown is related to the country of registration: so much so that the word "flag" is often used symbolically as a metonym for "country of registration".
Ensign is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the regimental colours, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, liwa', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general.
Identification badges of the uniformed services of the United States are insignia worn by service members conducting special duties, many of which can be awarded as permanent decorations if those duties are performed successfully. There are a few identification badges that are awarded to all services, others are specific to a uniform service. The Office of the President and Vice President and department/service headquarters badges are permanent decorations for those who successfully serve in those assignments. Some of the service level identification badges can be permanent decorations and others are only worn by a service member while performing specific duties, such as the Military Police Badge.
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 that officer exercises command.
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 brigadier general is a one-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
In the United States Armed Forces, a major general is a two-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
A rear admiral in four of the uniformed services of the United States is one of two distinct ranks of commissioned officers; "rear admiral (lower half)," a one-star flag officer, and "rear admiral" (sometimes referred to as "rear admiral (upper half)"), a two-star flag officer. The two ranks are only utilized by the United States Navy, U.S. Coast Guard, U.S. Public Health Service Commissioned Corps, and the National Oceanographic and Atmospheric Administration Commissioned Officer Corps. In contrast, in most other nations' rank-bearing services, the term "rear admiral" refers exclusively to two-star flag officer rank.
Vice admiral is a three-star commissioned officer rank in the United States Navy, the United States Coast Guard, the United States Public Health Service Commissioned Corps, the National Oceanic and Atmospheric Administration Commissioned Officer Corps, and the United States Maritime Service, with the pay grade of O-9. Vice admiral ranks above rear admiral and below admiral. Vice admiral is equivalent to the rank of lieutenant general in the other uniformed services.
In the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps, and National Oceanic and Atmospheric Administration Commissioned Officer Corps, captain is the senior-most commissioned officer rank below that of flag officer. The equivalent rank is colonel in the United States Army, Air Force, Space Force, and Marine Corps.
