Sergeant (Sgt) is a rank in use by the armed forces of many countries. It is also a police rank in some police services. The alternative spelling, serjeant, is used in The Rifles and other units that draw their heritage from the British light infantry. Its origin is the Latin serviens, 'one who serves', through the Old French term serjant.
Staff sergeant is a rank of non-commissioned officer used in the armed forces of many countries. It is also a police rank in some police services.
The chart below shows the current enlisted rank insignia of the United States Army, with seniority, and pay grade, increasing from right to left. The enlisted ranks of corporal (E-4) and higher are considered non-commissioned officers (NCOs). The rank of specialist is also in pay grade E-4, but does not hold non-commissioned officer status; it is common that a soldier may never hold the rank of corporal, and instead be promoted from specialist to sergeant, attaining junior NCO status at that time.
Inspector, also police inspector or inspector of police, is a police rank. The rank or position varies in seniority depending on the organization that uses it.
The fire service in France is organised into local fire services which mostly cover the Departments of France, with a few exceptions. There are two types of fire service:
The South African National Defence Force's rank system is largely based on the British system, with the Air Force sharing the Army rank titles. Rank titles changed over time as did the insignia.
The military ranks of Israel are the military insignia used by the Israel Defense Forces (IDF). Because the IDF is an integrated force, ranks are the same in all services The ranks are derived from those in the paramilitary Haganah, which operated during the Mandate period in order to protect the Yishuv.
Station officer is a supervisory rank in a number of Commonwealth and other fire services, including those in Australia, the United Kingdom, Ireland, and the New Zealand Fire Service.
For centuries, firefighters have worn helmets to protect them from heat, cinders and falling objects. Although the shape of most fire helmets has changed little over the years, their composition has evolved from traditional leather to metals, to composite helmets constructed of lightweight polymers and other plastics.
Chief fire officer (CFO), formerly often just chief officer, is the highest rank in the fire and rescue services of the United Kingdom. There are currently 50 chief fire officers serving in the United Kingdom in charge of the local authority fire services. There is also a chief fire officer responsible for the Ministry of Defence Fire Services, which includes the Defence Fire and Rescue Service and the RAF Fire Service. Some UK airport fire services also designate their seniors officers as CFOs, though these officers rarely wear the same rank insignia as a local authority chief fire officer.
Sub-officer, or the equivalent in other languages, is a term used in many armed forces used to indicate ranks below commissioned officers. Sub-officer is equivalent to the term warrant officer in the British Commonwealth and the United States. Historically armed forces using the term sub-officer have used it to refer to more senior non-commissioned ranks, typically from sergeant upwards, but the term often covers all ranks that other forces designate non-commissioned. In navies the term is comparable to petty officer.
Leading firefighter is a rank in the Isle of Man Fire and Rescue Service, London Fire Brigade and the Gibraltar Fire and Rescue Service. It used to be in all British fire services, ranking between firefighter and sub-officer. A leading firefighter was usually in charge of a single fire appliance. The badge of rank was one white or silver bar on the epaulettes. The helmet was yellow with one 12.5 mm (0.49 in) black stripe on it.
The Calgary Fire Department (CFD) provides fire services for the city of Calgary, Alberta.
Captain is a rank in various fire services.
Firefighting in the United States dates back to the earliest European colonies in the Americas. Early firefighters were simply community members who would respond to neighborhood fires with buckets. The first dedicated volunteer fire brigade was established in 1736 in Philadelphia. These volunteer companies were often paid by insurance companies in return for protecting their clients.
The United States police-rank model is generally quasi-military in structure. A uniform system of insignia based on that of the US Army and Marine Corps is used to help identify an officer's seniority.
The United States Army's enlisted rank insignia that was used during World War I differs from the current system. The color scheme used for the insignia's chevron was olive drab for field use uniforms or one of several colors depending on the corps on dress uniforms. The chevron system used by enlisted men during World War I came into being on July 17, 1902, and was changed to a different system in 1919. Specification 760, which was dated May 31, 1905, contained 45 different enlisted insignia that varied designs and titles by different corps of the Army. General Order Number 169, which was enacted on August 14, 1907, created an even larger variety of enlisted rank insignia. Pay grades similar to the current system were not yet in use by the U.S. Army, and instead, the pay system reflected the job assignment of the soldier rather than their rank. By the end of World War I, the system contained 128 different insignia designs.
The police in Canada's ranks differ according to the different police forces and depend on different laws at the federal, provincial, and municipal levels.
