A police officer (also known as a policeman or police agent in some forces, particularly in the United Kingdom and other Commonwealth nations) is a warranted law employee of a police force. In the United States, officer usually is the formal name of the lowest police rank. In many other countries, officer is a generic term not specifying a particular rank, and the lowest rank is often constable. In some nations the use of the rank officer is legally reserved for military personnel.
