Lieutenant Commander (LCDR) is a senior 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 (NOAA Corps), with the pay grade of O-4 and NATO rank code OF-3. Lieutenant commanders rank above lieutenants and below commanders. The rank is also used in the United States Maritime Service . The rank is equivalent to a major in the United States Army, United States Air Force, United States Marine Corps, and United States Space Force.
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 "full" commanders (which is one rank higher). Simply "lieutenant" is never used because it is one rank lower.
Promotion to lieutenant commander in the U.S. Navy is governed by United States Department of Defense policies derived from the Defense Officer Personnel Management Act of 1980. DOPMA guidelines suggest 80% of lieutenants should be promoted to lieutenant commander after serving a minimum of three years as lieutenants and after attaining nine to eleven years of cumulative commissioned service.[ citation needed ]
While lieutenant commander is the U.S. Navy's first commissioned officer rank to be selected by a board, lieutenant commanders are still considered to be junior officers due to their origin as "lieutenant, commanding". [ citation needed ]This can be seen by lieutenant commanders not wearing the headgear embellishment (colloquially known as "scrambled eggs") on their combination covers.
The U.S. Coast Guard used its own rank system until World War I. In 1916, discontent grew among Coast Guard captains:By law, they ranked below a lieutenant commander in the U.S. Navy despite similar roles and duties. Pursuant to the Appropriations Act of 1918, the Coast Guard adopted the U.S. Navy rank structure to prevent disagreements over seniority.
There are two insignia used by lieutenant commanders. On service khakis and all working uniforms, lieutenant commanders wear a gold oak leaf collar device, similar to the ones worn by majors in the United States Air Force and United States Army, and identical to that worn by majors in the United States Marine Corps. In all dress uniforms, they wear sleeve braid or shoulder boards bearing a single gold quarter-inch stripe between two gold half-inch strips (nominal size). In the case of officers of the U.S. Navy, above or inboard of the stripes, they wear their specialty insignia, notably a star for officers of the line, crossed oak leaves for Civil Engineer Corps.
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.
Commander is a common naval officer rank. 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.

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.
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 ensign flag, 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.
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.
A 5⁄16 inch star (9.7mm) is a miniature gold or silver five-pointed star that is authorized by the United States Armed Forces as a ribbon device to denote subsequent awards for specific decorations of the Department of the Navy, Coast Guard, Public Health Service, and National Oceanic and Atmospheric Administration. A gold star indicates a second or subsequent decoration, while a silver star is worn in lieu of five gold stars.
Mess dress uniform is the most formal type of uniforms used by military personnel, police personnel, and other uniformed services members. It frequently consists of a mess jacket, trousers, white dress shirt and a black bow tie, along with orders and medals insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In Western dress codes, mess dress uniform is the supplementary alternative equivalent to the civilian black tie for evening wear or black lounge suit for day wear although military uniforms are the same for day and evening wear. Mess dress uniforms are typically less formal than full dress uniform, but more formal than service dress uniform.
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.
The peaked cap, peaked hat, service cap, barracks cover or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor, or peak, which was historically made of polished leather but increasingly is made of a cheaper synthetic substitute.
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.
The Command at Sea insignia is a badge of the United States' seagoing services worn by officers on their uniforms to denote that they are the commander, or formerly a commander, of a warship. If the wearer is currently the commander of a warship, it is worn above the nametag, which is worn a quarter of an inch above the right chest pocket on a uniform shirt. Afterwards, the pin is moved to the left side of the shirt or jacket. For the commanders of land-based installations, a different but similar version known as the Command Ashore insignia instead.
In the United States Army, Marine Corps, Air Force and Space Force, colonel is the most senior field-grade military officer rank, immediately above the rank of lieutenant colonel and just below the rank of brigadier general. Colonel is equivalent to the naval rank of captain in the other uniformed services. By law, an officer previously required at least 22 years of cumulative service and a minimum of three years as a lieutenant colonel before being promoted to colonel. With the signing of the National Defense Authorization Act of 2019, military services now have the authorization to directly commission new officers up to the rank of colonel. The pay grade for colonel is O-6.
A shoulder mark, also called rank slide, or slip-on, is a flat cloth sleeve worn on the shoulder strap of a uniform. It may bear rank or other insignia. A shoulder mark should not be confused with a shoulder board, shoulder knot or epaulette, although these terms are often used interchangeably.
In the United States uniformed services, 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.
Gorget patches are an insignia in the form of paired patches of cloth or metal on the collar of a uniform (gorget), used in the military and civil service in some countries. Collar tabs sign the military rank, the rank of civil service, the military unit, the office (department) or the branch of the armed forces and the arm of service.
United States Coast Guard officer rank insignia describes an officer's pay-grade. Rank is displayed on collar devices, shoulder boards, and on the sleeves of dress uniforms.
A rear admiral in the uniformed services of the United States is either of two different ranks of commissioned officers: one-star flag officers and two-star flag officers. By contrast, in most other countries, the term "rear admiral" refers only to an officer of two-star rank.
Lieutenant is a commissioned officer rank in many English-speaking nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width.
In the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps (USPHS), 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.
