From the perspective of the U.S. Department of Defense, Chapter 18 of Title 10 United States Code refers to non-military law enforcement officers as civilians since they are employees rather than enlisted personnel, and also in order to distinguish itself from military police. In military and law enforcement slang, the term "Civies" or "Civvies" are often used to refer civilian population or civilian clothing. - A law enforcement officer (LEO) or peace officer, in North American English, is a public-sector employee whose duties primarily involve the enforcement of laws. The phrase can include police officers, municipal law enforcement officers, special police officers, customs officers, state troopers, special agents, special investigators, border patrol officers, immigration officers, court officers, probation officers, parole officers, arson investigators, auxiliary officers, game wardens, sheriffs, corrections, marshals, and deputies.

A "correctional system", also known as a "penal system", thus refers to a network of agencies that administer a jurisdiction's prisons and community-based programs like parole and probation boards;.

Individuals who have been granted these powers are known under the Act as Accredited Persons. - Special police (also see Auxiliary police) usually describes a police force or unit within a police force whose duties and responsibilities are significantly different from other forces in the same country or from other police in the same force, although there is no consistent international definition. A special constable, in most cases, is not a member of a special police force; in countries in the Commonwealth of Nations and often elsewhere, a special constable is a voluntary or part-time member of a national or local police force or a person involved in law enforcement who is not a police officer but has some of the powers of a police officer. - Parole officers and probation officers play a role in the criminal justice systems by supervising offenders released from incarceration or sentenced to non-custodial sanctions such as community service.
