supports: A navy or maritime force is a fleet of waterborne military vessels (watercraft) and its associated naval aviation, both sea-based and land-based. It is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields; recent developments have included space-related operations. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of Submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue-water navy), and something in between (green-water navy), although these distinctions are more about strategic scope than tactical or operational division. 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. Security guards are civilians and therefore not law enforcement officers, unless they have been granted powers to enforce particular laws, such as those accredited under a Community Safety Accreditation Scheme. Although typically the term "law enforcement officer" refers to those government agents with police powers, prosecutors are also law enforcement officers. A petty officer (PO) is a non-commissioned officer in many navies and is given the NATO rank denotion OR-6. They are equal in rank to sergeant in the British Army and Royal Air Force. A petty officer is superior in rank to leading rate and subordinate to chief petty officer, in the case of the British armed forces. A patrol is commonly a group of personnel , such as law enforcement officers or military personnel , that are assigned to monitor a specific geographic area . This is also often referred to as a beat . A security guard, security officer, or protective agent is a private person who is paid to protect an organization's assets (property, people, money, etc.) from a variety of hazards (such as waste, damaged property, unsafe worker behaviour, criminal activity, etc.) by utilizing preventative measures. They do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, observing (either directly, through patrols, or by watching alarm systems or video cameras) for signs of crime, fire or disorder; then taking action to minimize damage (example: warning and escorting trespassers off property) and reporting any incidents to their client and emergency services as appropriate. Their international (at least in the United States of America and Canada) symbol of brotherhood is The Thin Green Line. Security officers are generally uniformed to represent their lawful authority on private property. A warrant officer (WO) is an officer in a military organisation who is designated an officer by a warrant, as distinguished from a commissioned officer who is designated an officer by a commission, and a non-commissioned officer who is designated an officer, often by virtue of seniority. A coast guard or coastguard is a maritime security organization of a particular country. The term implies widely different responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue functions and lacking any law enforcement powers. However, a typical coast guard's functions are distinct from typical functions of both the "navy" (a pure military force) and a "transportation police" (a civilian law enforcement agency). A soldier is one who fights as part of an organised, land-based armed force. A soldier can be an enlisted person, a non-commissioned officer, or an officer. An army (from Latin "arma" "arms, weapons" via Old French "armée", "armed" (feminine)) or ground force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or state. It may also include other branches of the military such as the air force via means of aviation corps. Within a national military force, the word army may also mean a field army. They differ from army reserves who are activated only during such times as war or natural disasters. Military personnel are members of the armed forces. Usually, personnel are divided into military branches roughly defined by certain circumstances of their deployment. Those who serve in a typical large land force are soldiers, making up an army. Those who serve in seagoing forces are seamen or sailors, and their branch is a navy or coast guard . Marines serve in a marine corps. In the 20th century, the development of powered flight aircraft prompted the development of air forces, serviced by airmen. Designated leaders of military personnel are officers. These include commissioned officers, warrant officers and non-commissioned officers (NCOs). For naval forces, non-commissioned officers are referred to as petty officers (POs).
  military personnel are instructed to wear dog tags A non-commissioned officer or noncommissioned officer (NCO, colloquially non-com or noncom) is a military officer who has not earned a commission. Such is also called sub-officer in some countries. Non-commissioned officers, in the English-speaking world, usually obtain their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers hold higher ranks than NCOs, have more legal responsibilities, are paid more, and often have more non-military training such as a university diploma. Commissioned officers usually earn their commissions without having risen through the enlisted ranks. "Mustang" is a slang term in the United States Armed Forces used to refer to a commissioned officer who began his or her career as an enlisted service member. The armed forces of a country are its government-sponsored defense, fighting forces, and organizations. They exist to further the foreign and domestic policies of their governing body and to defend that body and the nation it represents from external and internal aggressors. In broad usage, the terms "armed forces" and "military" are often treated synonymously, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. Armed force is the use of armed forces to achieve political objectives.
  The study of the use of armed forces is called military science. Broadly speaking, this involves considering offense and defense at three "levels": strategy, operational art, and tactics. All three levels study the application of the use of force in order to achieve a desired objective.
