M4 Carbine
The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) is a 5.56×45mm NATO assault rifle developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the US military, with decisions to largely replace the M16 rifle in US Army (starting 2010) and US Marine Corps (starting 2016) combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century." Since its adoption in 1994, the M4 has undergone over 90 modifications to improve the weapon's adaptability, ergonomics and modularity, including: the M4A1, which possesses a thicker barrel and a replacement of the burst-fire control group with a fully automatic one; the SOPMOD, an accessory kit containing optical attachments; and the underbarrel weapons such as M203 and M320 grenade launchers to the Masterkey and M26-M ...

STANAG Magazine
A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980. Shortly after NATO's acceptance of the 5.56×45mm NATO rifle cartridge, Draft Standardization Agreement ( STANAG) 4179 was proposed in order to allow NATO members to easily share rifle ammunition and magazines down to the individual soldier level. The U.S. M16 rifle's magazine proportions were proposed for standardization. Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. However, the standard was never ratified and remains a "Draft STANAG". Magazines The STANAG magazine concept is only an interface, dimensional and controls (magazine latch, bolt stop, etc.) requirement. Therefore, it not only allows one type of magazine to interface with various weapon systems, but also allows STANAG magazines to be made in various configurations and capacities. The standard capacities of STANAG-compatible mag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Firearm
An automatic firearm or fully automatic firearm (to avoid confusion with semi-automatic firearms) is a self-loading firearm that continuously Chamber (firearms), chambers and fires Cartridge (firearms), rounds when the trigger (firearms), trigger mechanism is actuated. The action (firearms), action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition cartridge (firearms), round into the chamber (firearms), chamber, and then igniting the propellant and discharging the projectile (either bullet, shot (pellet), shot, or shotgun slug, slug) by delivering a hammer (firearms), hammer or firing pin, striker impact on the primer (firearms), primer. If ''both'' the feeding and ignition procedures are automatically cycled, the weapon will be considered "fully automatic" and will fire continuously as long as the trigger is kept depressed and the ammunition feeding (either from a magazine (firearms), magazine or a belt ...

Burst Mode (weapons)
In automatic firearms, burst mode or burst-fire is a firing mode enabling the shooter to fire a predetermined number of rounds, usually two or three rounds on hand held weapons to fifty or more rounds on autocannons, with a single pull of the trigger. This firing mode is commonly used in submachine guns and assault rifles. Other types of firearms, such as machine pistols, including the Heckler & Koch VP70 and Beretta 93R also have a burst mode. The burst mode is normally employed as an intermediate fire mode between semi-automatic and fully automatic, although some firearms lack a "full auto" capability and use a burst mode instead. For instance, the M16A4 (the standard-issue service rifle of the USMC) has, in addition to the semi-automatic mode, a three-round burst mode, which replaced the fully automatic mode of the previous M16A1 and M16A3 models. The reason for this replacement was the massive waste of ammunition and very poor performance of soldiers who fired their r ...

Modularity
Modularity is the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use. The concept of modularity is used primarily to reduce complexity by breaking a system into varying degrees of interdependence and independence across and "hide the complexity of each part behind an abstraction and interface". However, the concept of modularity can be extended to multiple disciplines, each with their own nuances. Despite these nuances, consistent themes concerning modular systems can be identified. Composability is one of the tenets of functional programming. This makes functional programs modular. Contextual nuances The meaning of the word "modularity" can vary somewhat based on context. The following are contextual examples of modularity across several fields of science, technology, industry, and culture: Science *In biology, modularity recognizes that organisms or metabolic pathways are composed of modules. *I ...

Ergonomics
Ergonomics, also known as human factors or human factors engineering (HFE), is the application of Psychology, psychological and Physiology, physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error, increase productivity and system availability, and enhance safety, health and comfort with a specific focus on the interaction between the human and equipment. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to previously stated goals. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its Cog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adaptability
Adaptability ( "fit to, adjust") is a feature of a system or of a process. This word has been put to use as a specialised term in different disciplines and in business operations. Word definitions of adaptability as a specialised term differ little from dictionary definitions. According to Andresen and Gronau adaptability in the field of organizational management can in general be seen as an ability to change something or oneself to fit to occurring changes. In ecology, adaptability has been described as the ability to cope with unexpected disturbances in the environment. With respect to business and manufacturing systems and processes, adaptability has come to be seen increasingly as an important factor for their efficiency and economic success. In contrast, adaptability and efficiency are held to be in opposition to each other in biological and ecological systems, requiring a trade-off, since both are important factors in the success of such systems. To determine the adaptabili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Service Rifle
A service rifle (or standard-issue rifle) is a rifle a military issues to its regular infantry. In modern militaries, this is generally a versatile, rugged, and reliable assault rifle or battle rifle, suitable for use in nearly all environments and is effective in most combat situations. Almost all modern militaries are issued service pistols as sidearms to accompany their service rifles. The term can also be used to describe weapons issued by non-military forces, such as law enforcement or paramilitaries. If the issued weapon is not a rifle or carbine, but instead a different type of firearm intended to serve in a specialized role such as a combat shotgun, submachine gun, or light machine gun, it is called a service firearm or service weapon. History Firearms with rifled barrels existed long before the 19th century, but were not widely used until the mid-19th century in conflicts such as the Crimean War and American Civil War. Thus, rifles in the early 19th century were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infantry
Infantry, or infantryman are a type of soldier who specialize in ground combat, typically fighting dismounted.

In modern usage, the term broadly encompasses a wide variety of subspecialties, including light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, Airborne forces, airborne infantry, Air assault, air assault infantry, and Marines, naval infantry. Other subtypes of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French , from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' ...
