The United States Armed Forces are the military forces of the United States of America. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States.
Lieutenant commander is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader.
First lieutenant is a commissioned officer military rank in many armed forces; in some forces, it is an appointment.
In the United States Navy, officers have various ranks. Equivalency between services is by pay grade. United States Navy commissioned officer ranks have two distinct sets of rank insignia: On dress uniform a series of stripes similar to Commonwealth naval ranks are worn; on service khaki, working uniforms, and special uniform situations, the rank insignia are identical to the equivalent rank in the US Marine Corps.
The United States Public Health Service Commissioned Corps (PHSCC), also referred to as the Commissioned Corps of the United States Public Health Service, is the federal uniformed service of the U.S. Public Health Service (PHS), and is one of the eight uniformed services of the United States. The commissioned corps' primary mission is the protection, promotion, and advancement of health and safety of the general public.
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.
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.
In the United States Armed Forces, a line officer or officer of the line is a U.S. Navy or U.S. Marine Corps commissioned officer or warrant officer who exercises general command authority and is eligible for operational command positions, as opposed to officers who normally exercise command authority only within a Navy Staff Corps. The term line officer is also used by the U.S. Air Force and U.S. Coast Guard to indicate that an officer is eligible for command of operational, viz., tactical or combat units. The term is not generally used by officers of the U.S. Army – the roughly corresponding Army terms are basic branch and special branch, qualified officers, although the concepts are not entirely synonymous, as some Army special branch officers are eligible to hold command outside their branch specialty.
In many of the world's military establishments, a brevet was a warrant giving a commissioned officer a higher rank title as a reward for gallantry or meritorious conduct but may not confer the authority, precedence, or pay of real rank. An officer so promoted was referred to as being brevetted. The promotion would be noted in the officer's title.
In the United States Army, U.S. Marine Corps, U.S. Air Force and U.S. 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.
Pay grades are used by the eight uniformed services of the United States to determine wages and benefits based on the corresponding military rank of a member of the services. While different titles or ranks may be used among the eight uniformed services, pay grades are uniform and equivalent between the services and can be used to quickly determine seniority among a group of members from different services. They are also essential when determining a member's entitlements such as basic pay and allowances.
These are the official Royal Navy Officer ranks ordered by rank. These ranks are part of the NATO/United Kingdom ranks, including modern and past. Past insignia is in italic.
Lieutenant commander is a Junior Officer rank in the United States Navy, the United States Coast Guard, the United States Public Health Service Commissioned Corps, and the National Oceanic and Atmospheric Administration Commissioned Officer Corps, with the pay grade of O-4 and NATO rank code OF-3. When introducing a lieutenant commander their full rank should always be used; however, in general conversation they are usually called "commander" even though they are not a "full" commander. Never use just "lieutenant" because it is one rank lower. The predecessors of the NOAA Corps, the United States Coast and Geodetic Survey Corps (1917–1965) and the Environmental Science Services Administration Corps (1965–1970), also used the lieutenant commander rank, and the rank is also used in the United States Maritime Service and the United States Naval Sea Cadet Corps. Lieutenant commanders rank above lieutenants and below commanders, and rank is equivalent to a major in the United States Army, United States Air Force, and United States Marine Corps.
The utility cover, also known as the utility cap and eight-pointed cover, is the United States Marine Corps cap, worn with their combat utility uniform. It is an eight-pointed hat, with a visor similar to a baseball cap. It is worn "blocked", that is, creased and peaked, for a sharper appearance. A version is also worn as part of the U.S. Navy's Navy Working Uniform.
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, armor, artillery, aerial and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States.
The Intelligence Support Battalion (ISB) is the battalion in the United States Marine Corps which provides military intelligence for the Marine Forces Reserve. It is part of the Force Headquarters Group. They have detachments located throughout the United States and Marines from this unit have deployed all over the world in numerous billets supporting the War on Terror.
The Marine Forces Reserve, also known as the United States Marine Corps Reserve (USMCR) and the U.S. Marine Corps Forces Reserve, is the reserve force of the United States Marine Corps. It is the largest command, by assigned personnel, in the U.S. Marine Corps. Marines in the Reserve go through the same training and work in the same Military Occupational Specialties (MOS) as their active-duty counterparts. The United States Marine Corps Reserve was established when Congress passed the Naval Appropriations Act of 29 August 1916, and is responsible for providing trained units and qualified individuals to be mobilized for active duty in time of war, national emergency, or contingency operations.
The "Marines' Hymn" is the official hymn of the United States Marine Corps, introduced by the first director of the USMC Band, Francesco Maria Scala. Its music originates from an 1867 work by Jacques Offenbach with the lyrics added by an anonymous author at an unknown time in the following years. Authorized by the Commandant of the Marine Corps in 1929, it is the oldest official song in the United States Armed Forces. The "Marines' Hymn" is typically sung at the position of attention as a gesture of respect. However, the third verse is also used as a toast during formal events, such as the birthday ball and other ceremonies.
An officer is a member of an armed forces or uniformed service who holds a position of authority.
The Junior Reserve Officers' Training Corps is a federal program sponsored by the United States Armed Forces in high schools and also in some middle schools across the United States and at US military bases across the world. The program was originally created as part of the National Defense Act of 1916 and later expanded under the 1964 ROTC Vitalization Act.
