Coast guard in the context of "Japan Coast Guard"

A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats.

In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police.

The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces. It is one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest coast guard in the world.

The U.S. Coast Guard protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across U.S. territorial waters and its Exclusive Economic Zone. Due to ever-expanding risk imposed by transnational threats through the maritime and cyber domains, the U.S. Coast Guard is at any given time deployed to and operating on all seven continents and in cyberspace to enforce its mission. Like its United States Navy sibling, the U.S. Coast Guard maintains a global presence with permanently-assigned personnel throughout the world and forces routinely deploying to both littoral and blue-water regions. The U.S. Coast Guard's adaptive, multi-mission "white hull" fleet is leveraged as a force of both diplomatic soft power and humanitarian and security assistance over the more overtly confrontational nature of "gray hulled" warships. As a humanitarian service, it saves tens of thousands of lives a year at sea and in U.S. waters, and provides emergency response and disaster management for a wide range of human-made and natural catastrophic incidents in the U.S. and throughout the world.

The Armed Forces of Ukraine (AFU) are the military forces of Ukraine. All military and security forces, including the Armed Forces, are under the command of the president of Ukraine and subject to oversight by a permanent Verkhovna Rada parliamentary commission. They trace their lineage to 1917, while the modern armed forces were formed again in 1991. The Armed Forces of Ukraine are the fifth largest armed force in the world in terms of both active personnel as well as total number of personnel with the eighth largest (14th largest) defence budget in the world, and it also operates one of the largest and most diverse drone fleets in the world. Due to the ongoing Russo-Ukrainian War, the Ukrainian Armed Forces has been described as "the most battle-hardened in Europe," but has suffered many casualties.

Ukraine's armed forces are composed of the Ground Forces, the Air Force, the Navy, the Air Assault Forces, the Marine Corps, the Special Operations Forces, the Unmanned Systems Forces, and the Territorial Defense Forces. Ukraine's navy includes its own Naval Aviation. The Sea Guard is the coast guard service of Ukraine, and it is organized as part of the Border Guard Service, not subordinate to the navy. The National Guard serves as a paramilitary reserve component of the Armed Forces.

Naval aviation is the application of military air power by navies, either from warships that can embark aircraft (e.g. aircraft carriers, amphibious assault ships and aircraft cruisers) or from coastal naval air stations.It often involves navalised aircraft, specifically designed for naval use.Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators. As with most army aviation units, naval aviation units are generally separate from a nation's dedicated air force.

Naval aviation operations are typically projected by way of carrier-based aircraft, which must be sturdy enough to withstand the demands of shipborne operations at sea. They must be able to take off from a short runway (typically the flight deck of an aircraft carrier) and be sturdy and flexible enough to come to a sudden stop when landing; they typically have robust folding or swinging wings that reduce the occupied space and thus allow more of them to be stored in below-decks hangars and limited parking spaces on flight decks. These aircraft are designed for many tactical purposes, including aerial combat, airstrike/close air support, anti-submarine warfare, early warning, search and rescue, matériel transport, weather observation, patrol and reconnaissance, and wide-area command and control duties.

Military personnel or military service members are members of the state's armed forces. Their roles, pay, and obligations differ according to their military branch (army, navy, marines, coast guard, air force, and space force), rank (officer, non-commissioned officer, or enlisted recruit), and their military task when deployed on operations and on exercise.

The War of Jenkins' Ear was fought between Great Britain and Spain from 1739 to 1748. Most of the fighting took place in New Granada and the Caribbean Sea, with major operations over by 1742. It is considered a related conflict of the 1740 to 1748 War of the Austrian Succession.

The name derives from Robert Jenkins, a British sea captain whose ear was allegedly severed in April 1731 by Spanish coast guards searching his ship for contraband. In 1738, opposition politicians in the British Parliament used the incident to incite support for a war against Spain.
