Information: - An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first used during World War II. Though Western nations were slow to accept the assault rifle concept after World War II, by the end of the 20th century they had become the standard weapon in most of the world's armies, replacing semi-automatic rifles, battle rifles and sub-machine guns in most roles. Examples include the StG 44, AK-47 and the M16 rifle. - Fabrique Nationale d'Herstal (French for: National Factory of Herstal) self identified as FN Herstal and often referred to as Fabrique Nationale or simply FN is a leading firearms manufacturer located in Herstal, Belgium, and is owned by the holding company Herstal Group which is owned by the regional government of Wallonia. It is currently the largest exporter of military small arms in Europe. - The CAL ( Carabine Automatique Legere ) was a Belgian weapon manufactured by Fabrique Nationale . It was the first 5.56 mm rifle produced by the Fabrique Nationale . It resembled the company 's highly successful FN FAL , but was an original design . Unlike the FAL , it was a market failure , although its development led to the reasonably successful FN FNC . - A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.6251mm NATO, 7.6254mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire. - The 5.5645mm NATO (official NATO nomenclature 5.56 NATO) is an intermediate cartridge developed in the United States and originally chambered in the M16 rifle. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries. It is derived from, but is not identical to, the .223 Remington cartridge. - The FN FNC (French: "Fabrique Nationale Carabine") is a 5.5645mm NATO assault rifle developed by the Belgian arms manufacturer FN Herstal and introduced in the late 1970s. - The FAL, or Fusil Automatique Leger ("Light Automatic Rifle"), is a semi-automatic/selective fire battle rifle produced by the Belgian armaments manufacturer Fabrique Nationale de Herstal (FN). During the Cold War it was adopted by many North Atlantic Treaty Organization (NATO) countries, with the notable exception of the United States. It is one of the most widely used rifles in history, having been used by more than 90 countries. - A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls. The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon. When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling, in the same way that a properly thrown American football or rugby ball behaves. This allows the use of aerodynamically-efficient bullets (as opposed to the spherical balls used in muskets) and thus improves range and accuracy. The word "rifle" originally referred to the grooving, and a rifle was called a "rifled gun." Rifles are used in warfare, hunting and shooting sports. - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed. - The North Atlantic Treaty Organization (NATO '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22countries participate in NATO's Partnership for Peace program, with 15other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP. - A selective-fire firearm has at least two firearm modes, which are activated by means of a selector which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released. Semi-automatic refers to the ability to fire one round per trigger pull. What is the relationship between 'fn cal' and 'assault rifle'?
