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. It is roughly equivalent to the Corvette Captain rank in central European countries and the Captain 3rd rank rank in eastern European/CIS countries.
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.
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.
A service stripe is an embroidered diagonal stripe worn on the sleeve(s) of some military and paramilitary uniforms. In the case of the United States military, service stripes are authorized for wear by enlisted personnel on the lower part of the sleeve of a uniform to denote length of service. Service stripes vary in size and in color.
Mess dress uniform is the most formal type of evening-wear uniform 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 modern Western dress codes, mess dress uniform is the supplementary alternative equivalent to the civilian black tie for 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.
Insignias and badges of the United States Navy are military badges issued by the United States Department of the Navy to naval service members who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Navy. Most naval aviation insignia are also permitted for wear on uniforms of the United States Marine Corps.
A 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.
A colonel in the United States Army, Marine Corps, Air Force and Space Force, 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.
These are the official Royal Navy Officer ranks ordered by rank. These ranks are now part of the NATO/United Kingdom ranks, including modern and past.
A shoulder mark, also called a 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, a shoulder knot, or an epaulette, although these terms are often used interchangeably.
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.
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.
The uniforms of the United States Air Force are the standardized military uniforms worn by members of the United States Air Force to distinguish themselves from the other services.
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 (abbreviated Lt, LT (U.S.), LT(USN), Lieut and LEUT, depending on nation) 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, 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.
