United States Federal Civil Service
The United States federal civil service is the civilian workforce (i.e., non-elected and non-military public sector employees) of the United States federal government's departments and agencies. The federal civil service was established in 1871 (). U.S. state and local government entities often have comparable civil service systems that are modeled on the national system, in varying degrees. The U.S. civil service is managed by the Office of Personnel Management, which reported approximately 2.79 million civil servants employed by the federal government, including employees in the departments and agencies run by any of the three branches of government (the executive branch, legislative branch, and judicial branch), including over 600,000 employees in the U.S. Postal Service. Types of employees There are three categories of U.S. federal employees: * The '' competitive service'' includes the majority of civil service positions, meaning employees are selected based on merit after ...

Chemical
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, ...

Lieutenant Colonel
Lieutenant colonel ( , ) is a rank of commissioned officers in the armies, most marine forces and some air forces of the world, above a major and below a colonel. Several police forces in the United States use the rank of lieutenant colonel. The rank of lieutenant colonel is often shortened to simply "colonel" in conversation and in unofficial correspondence. Sometimes, the term 'half-colonel' is used in casual conversation in the British Army. In the United States Air Force, the term 'light bird' or 'light bird colonel' (as opposed to a 'full bird colonel') is an acceptable casual reference to the rank but is never used directly towards the rank holder. A lieutenant colonel is typically in charge of a battalion or regiment in the army. The following articles deal with the rank of lieutenant colonel: * Lieutenant-colonel (Canada) * Lieutenant colonel (Eastern Europe) * Lieutenant colonel (Turkey) * Lieutenant colonel (Sri Lanka) * Lieutenant colonel (United Kingdom) * L ...

Chemical Corps
The Chemical Corps is the branch of the United States Army tasked with defending against chemical, biological, radiological, and nuclear (CBRN) weapons. The Chemical Warfare Service was established on 28 June 1918, combining activities that until then had been dispersed among five separate agencies of the United States federal government. It was made a permanent branch of the Regular Army by the National Defense Act of 1920. In 1945, it was redesignated the Chemical Corps. History Origins Discussion of the topic dates back to the American Civil War. A letter to the War Department dated 5 April 1862 from New York City resident John Doughty proposed the use of chlorine shells to drive the Confederate Army from its positions. Doughty included a detailed drawing of the shell with his letter. It is unknown how the military reacted to Doughty's proposal but the letter was unnoticed in a pile of old official documents until modern times. Another American, Forrest Shepherd, also propos ...

Second Lieutenant
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank. Australia The rank of second lieutenant existed in the military forces of the Australian colonies and Australian Army until 1986. In the colonial forces, which closely followed the practices of the British military, the rank of second lieutenant began to replace ranks such as ensign and cornet from 1871. New appointments to the rank of second lieutenant ceased in the regular army in 1986. Immediately prior to this change, the rank had been effectively reserved for new graduates from the Officer Cadet School, Portsea which closed in 1985. (Graduates of the Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC-D) are commissioned as lieutenants.). The rank of second lieutenant is only appointed to officers in special appointments such as training institutions, university regiments and while under probation during training. Trai ...

Commissioned Officer
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, 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. Numbers The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces. Historically, however, armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly ...

Enlisted Rank
An enlisted rank (also known as an enlisted grade or enlisted rate) is, in some armed services, any rank below that of a commissioned officer. The term can be inclusive of non-commissioned officers or warrant officers, except in United States military usage where warrant officers/chief warrant officers are a separate officer category ranking above enlisted grades and below commissioned officer grades. In most cases, enlisted service personnel perform jobs specific to their own occupational specialty, as opposed to the more generalized command responsibilities of commissioned officers. The term "enlistment" refers solely to a military commitment (whether officer or enlisted) whereas the terms "taken on strength" and "struck off strength" refer to a service member being carried on a given unit's roll. Canadian Forces In the Canadian Forces, the term non-commissioned member (NCM) is used. North Atlantic Treaty Organization For the ranks used by the North Atlantic Treaty Organizat ...
