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.

Commendation Medal

The Commendation Medal is a mid-level United States military decoration which is presented for sustained acts of heroism or meritorious service. For valorous actions in direct contact with an enemy, but of a lesser degree than required for the award of the Bronze Star Medal, a Commendation Medal with "V" Device or Combat "V" (Navy/Marine) is awarded; the "V" device may be authorized for wear on the service and suspension ribbon of the medal to denote valor. Each branch of the United States Armed Forces issues its own version of the Commendation Medal, with a fifth version existing for acts of joint military service performed under the Department of Defense.

The Commendation Medal was originally only a service ribbon and was first awarded by the U.S. Navy and U.S. Coast Guard in 1943. An Army Commendation Ribbon followed in 1945, and in 1949, the Navy, Coast Guard, and Army Commendation ribbons were renamed the "Commendation Ribbon with Metal Pendant." By 1960, the Commendation Ribbons had been authorized as full medals and were subsequently referred to as Commendation Medals.

Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Achievement Medal

The Achievement Medal is a military decoration of the United States Armed Forces. The Achievement Medal was first proposed as a means to recognize the contributions of junior officers and enlisted personnel who were not eligible to receive the higher Commendation Medal or the Meritorious Service Medal.

Each military service issues its own version of the Achievement Medal, with a fifth version authorized by the U.S. Department of Defense for joint military activity. The Achievement Medal is awarded for outstanding achievement or meritorious service not of a nature that would otherwise warrant awarding the Commendation Medal. Since the Achievement Medal is designated as an award solely for junior personnel, it is generally only awarded to officers in the pay grade of O-4 and below and enlisted personnel below the grade of E-7. Award authority rests with local commanders, granting a broad discretion of when and for what action the Achievement Medal may be awarded.

Medal

A medal or medallion is, strictly speaking, a small, flat, and round (at times, ovoid) piece of metal that has been sculpted, molded, cast, struck, stamped, or some way marked with an insignia, portrait, or other artistic rendering. A medal may be awarded to a person or organization as a form of recognition for sporting, military, scientific, academic, or various other achievements. Military awards and decorations are more precise terms for certain types of state decoration. Medals may also be created for sale to commemorate particular individuals or events, or as works of artistic expression in their own right. In the past, medals commissioned for an individual, typically with his portrait, were often used as a form of diplomatic or personal gift, with no sense of being an award for the conduct of the recipient.

An artist who creates medals or medallions is called a "medallist" (UK) or "medalist" (US). There are also devotional medals which may be worn for religious reasons. Medals have long been popular collectible items either as a variety of exonumia or of militaria. Medals may also be produced in a rectangular shape, though these would more correctly be described as a plaquette, and official awards such as military decorations are often in shapes such as crosses or stars, but are still loosely called "medals", as in the star-shaped American Medal of Honor.
