Uniformed services in the context of Domestic worker

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 United States Public Health Service Commissioned Corps (USPHSCC; also referred to as the Commissioned Corps of the United States Public Health Service) is the uniformed service branch of the United States Public Health Service and one of the eight uniformed services of the United States (along with the Army, Navy, Marine Corps, Coast Guard, Air Force, Space Force, and NOAA Commissioned Officer Corps). The commissioned corps' primary mission is the protection, promotion, and advancement of health and safety of the general public.

Along with the NOAA Commissioned Officer Corps, the Public Health Service Commissioned Corps is one of two uniformed services that consist only of commissioned officers and has no enlisted or warrant officer ranks, although warrant officers have been authorized for use within the service. Officers of the commissioned corps are classified as noncombatants, unless directed to serve as part of the military by the president or detailed to a service branch of the military. Members of the commissioned corps wear uniforms modeled after the United States Navy and the United States Coast Guard, with special Public Health Service Commissioned Corps insignia, and hold naval ranks equivalent to officers of the Navy and Coast Guard, along with corresponding in-service medical titles. Commissioned corps officers typically receive their commissions through the commissioned corps's direct commissioning program.

An officer is a person who holds a position of authority as a member of an armed force or uniformed service.

Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer (NCO), or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's commissioned officers, the more senior members who derive their authority from a commission from the head of state.

The Pakistan Armed Forces (Urdu: پاکستان مسلح افواج; pronounced [ˈpɑːkˌɪstaːn mʊˈsəlˌle(ɦ) əfˈwɑːd͡ʒ]) are the military forces of Pakistan. It is the world's seventh-largest military measured by active military personnel and consists of three uniformed services—the Army, Navy, and the Air Force, which are backed by several paramilitary forces such as the National Guard and the Civil Armed Forces. As of the 2025 reforms, the highest-ranking military officer is the Chief of Defence Forces (CDF), who also serves concurrently as Chief of Army Staff (COAS), holding principal command authority over all three branches and overseeing war strategy, operations, joint force development, and resource allocation. The office of Chairman Joint Chiefs of Staff Committee (CJCSC) has been abolished, and many prior responsibilities are now assumed by the CDF, streamlining military command and accelerating decision-making.

A pivotal part of the 2025 reforms is the formation of the position of Commander of National Strategic Command (CNSC), a four-star army general appointed by the Prime Minister upon the CDF’s recommendation and is responsible for Pakistan’s nuclear and strategic assets. The Strategic Plans Division remains crucial, managing nuclear policy of Pakistan and national deterrent under the CNSC’s supervision. The President of Pakistan is the commander-in-chief of the Pakistan Armed Forces. All branches of Pakistan Armed Forces are now coordinated through the Chief of Defence Forces (CDF), who directs strategic planning, resource allocation, and joint military operations, with the Joint Staff Headquarters (JSHQ) being reorganised to support integrated command across all services from the Joint Staff Headquarters (JSHQ).

A prison officer (PO) or corrections officer (CO), also known as a correctional law enforcement officer or less formally as a prison guard, is a uniformed law enforcement official responsible for the custody, supervision, safety, and regulation of prisoners.

A combat uniform, also called a field uniform, battledress, or military fatigues, is a casual uniform used by military, police, fire, and other public uniformed services for everyday fieldwork and duty, as opposed to dress uniforms for formal functions and parades. It generally consists of a jacket, trousers, and shirt or T-shirt, all cut to be looser and more comfortable than more formal uniforms. Combat uniform designs vary by regiment or service branch (e.g. army, navy, air force, marines, etc.). Uniform fabrics often come in camouflage, disruptive patterns, or otherwise olive drab, brown, or khaki monochrome, to approximate the background and make the soldier less conspicuous in the field. In Western dress codes, field uniforms are considered equivalent to civilian casual wear, less formal than service dress uniforms, which are generally for office or staff use, as well as mess dress uniforms and full dress uniforms.

Combat uniforms have existed to some degree in most organized militaries throughout history, with the intent of providing both protection and easy identification. The British Indian Army's Corps of Guides were the first to use drab combat uniforms starting in 1848, when they wore light-brown clothing called "khaki" by Indian troops. The Second Boer War and World War I ended the pre-modern practice of issuing brightly-colored combat uniforms in favor of green, brown, khaki, and grey uniforms that better suited the varied environments of modern warfare. The first proper military camouflage pattern was Italy's telo mimetico, originally designed for half-shelters in 1929. Germany's Wehrmacht began issuing camouflage uniforms to paratroopers during World War II, and by the end of the war, both the Allies and Axis made use of camouflage uniforms for select units, usually special forces. The Cold War and post–Cold War era saw the gradual shift from monochromatic olive and khaki combat uniforms to those using camouflage patterns.

Full dress uniform, also known as a ceremonial dress uniform or parade dress uniform, is among the most formal type of uniform used by military, police, fire and other public uniformed services for official parades, ceremonies, and receptions, including private ones such as marriages and funerals. Full dress uniforms typically include full-size orders and medals insignia. Styles tend to originate from 19th-century uniforms, although the 20th century saw the adoption of mess dress-styled full-dress uniforms. Designs may depend on regiment or service branch (e.g. army, navy, air force, marines). In Western dress codes, full dress uniform is a permitted supplementary alternative equivalent to the civilian white tie for evening wear or morning dress for day wear – sometimes collectively called full dress – although military uniforms are the same for day and evening wear. As such, full dress uniform is the most formal uniform, followed by the mess dress uniform.

Although full dress uniforms are often brightly coloured and ornamented with gold epaulettes, braids, lanyards, lampasses, etc., many originated in the 18th and early 19th centuries as normal styles of military dress that, with the adoption of more practical uniforms, were eventually relegated to ceremonial functions. Before World War I, most armed forces of the world retained uniforms of this type that were usually more colourful and elaborate than the ordinary duty (known as undress), or the active service dress uniform.

The Vietnam People's Armed Forces (Vietnamese: Lực lượng Vũ trang nhân dân Việt Nam (LLVTNDVN)) are the armed uniformed services and national security forces of the Socialist Republic of Vietnam, and should not be confused with the People’s Army of Vietnam. The Armed Forces are placed under the political leadership of the sole-ruling Communist Party of Vietnam and under the supreme command of the Central Military Commission of the Communist Party of Vietnam. It consists of three components: the Vietnam People's Army which is the military of Vietnam, the Vietnam People's Public Security which is the law enforcement agency (police) of Vietnam and Vietnam Militia and Self-Defence Force which is the militia of Vietnam.

A brassard or armlet is an armband or piece of cloth or other material worn around the upper arm; the term typically refers to an item of uniform worn as part of military uniform or by police or other uniformed persons. Unit, role, rank badges or other insignia are carried on it instead of being stitched into the actual clothing. The brassard, when spread out, may be roughly rectangular in shape, where it is worn merely around the arm; it may also be a roughly triangular shape, in which case the brassard is also attached to a shoulder strap. The term is originally French, deriving from bras meaning "arm".

Brassards are also used with the uniforms of organizations which are not military, but which are influenced by and styled upon the military, such as police, emergency services, volunteer services, or militaristic societies and political parties.

Service dress uniform is the informal type of uniform used by military, police, fire and other public uniformed services for everyday office, barracks and non-field duty purposes and sometimes for ceremonial occasions. It frequently consists of a jacket, trousers, dress shirt, and neck tie, along with orders, medals, and insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In Western dress codes, a service dress uniform is a permitted supplementary alternative equivalent to the civilian suit—sometimes collectively called undress or "dress clothes". As such, a service dress uniform is considered less formal than both full dress and mess dress uniforms, but more formal than combat uniforms.

Service dress uniforms were originally worn in active service in the field or at sea, but became relegated to office, barracks, and walking out dress as more practical field uniforms evolved. In some parts of some armed forces such as the British Army, service dress uniform may also be used for ceremonial occasions, gradually replacing in this role the full dress uniforms that had preceded them as field uniforms. In the United States Navy, for example, service dress uniforms are worn for official functions not rising to the level of full dress or mess dress uniforms. They are also commonly worn when travelling in official capacity, or when reporting to a command. They may be seasonal, with a white uniform worn in summer and darker versions in winter.

Mess dress uniform is the most formal (or semi-formal, depending on the country) 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, medals, and 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.

Prior to World War II, this style of military uniform was largely restricted to the British and United States Armed Forces, although the French, German, Swedish and other navies had adopted their own versions of mess dress during the late 19th century, influenced by the British Royal Navy.
