Marines

Marines, also known as a marine corps and naval infantry, are an infantry force that specializes in the support of naval and army operations on land and at sea, as well as the execution of their own operations. In the majority of countries, the marine force is part of the navy, but it can also be under the army like the Troupes de marine (French Marines) and Givati Brigade (Israeli Marines), or form an independent armed service branch like the United States Marine Corps and Royal Marines.

Historically, tasks undertaken by marines have included providing protection from war while at sea, reflecting the pressed nature of the ships' company and the risk of mutiny. Other tasks would include boarding of vessels during combat or capture of prize ships and providing manpower for raiding ashore in support of the naval objectives.

With the industrialization of warfare in the 20th century the scale of landing operations increased; this brought with it an increased likelihood of opposition and a need for co-ordination of various military elements. Marine forces evolved to specialize in the skills and capabilities required for amphibious warfare.

San Diego

San Diego /ˌsæn diːˈeɪɡoʊ/ (Spanish for "Saint Didacus") is a major city in California, on the coast of the Pacific Ocean in Southern California, approximately 120 miles (190 km) south of Los Angeles and immediately adjacent to the border with Mexico.

With an estimated population of 1,381,069 as of July 1, 2014, San Diego is the eighth-largest city in the United States and second-largest in California. San Diego is the birthplace of California and is known for its mild year-round climate, natural deep-water harbor, extensive beaches, long association with the U.S. Navy, and recent emergence as a healthcare and biotechnology development center.

Historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the entire area for Spain, forming the basis for the settlement of Alta California 200 years later. The Presidio and Mission of San Diego, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of newly independent Mexico, and in 1850, became part of the United States following the Mexican–American War and the admission of California to the union.

Marine

Marine is an umbrella term. As an adjective it is usually applicable to things relating to the sea or ocean, such as marine biology, marine ecology and marine geology. In scientific contexts, the term almost always refers exclusively to saltwater environments, although in other contexts (e.g., engineering) it may refer to any (usually navigable) body of water.

Marine or marines may also refer to:

Recruit training

Recruit training, more commonly known as Basic Training and colloquially called boot camp, is the initial indoctrination and instruction given to new military personnel, enlisted and officer. After completion of Basic Training, new recruits undergo Advanced Individual Training (AIT), where they learn the skills needed for their military jobs. Officer trainees undergo more detailed programs that may either precede or follow the common recruit training in an officer training academy (which may also offer a civilian degree program simultaneously) or in special classes at a civilian university. During recruit training, drill instructors do everything possible to push a recruit to his or her physical and mental limits.

Preface

Recruit training varies by nation according to the national requirement and can be voluntary (volunteer military) or mandatory (conscription). Approximately 100 nations, including the United Kingdom and United States, have a volunteer military service. In voluntary service an individual chooses to join and thereby agrees to be subjected to the process of building an organization where each life depends on the person next to them. This voluntary status has changed the culture of military service.
