Light machine gun {LMG}

A light machine gun (LMG) is a machine gun designed to be employed by an individual soldier, with or without an assistant, as an infantry support weapon. Light machine guns are often used as squad automatic weapons.

Characteristics

Modern light machine guns often fire smaller-caliber cartridges than medium machine guns, and are usually lighter and more compact. Some LMGs, such as the Russian RPK, are modifications of existing assault rifle designs and designed to share the same ammunition. Adaptations to the original rifle generally include a larger magazine, a heavier barrel to resist overheating, a more robust mechanism to support sustained fire and a bipod.

A light machine gun is also defined by its usage as well as its specifications: some machine guns - notably general-purpose machine guns - may be deployed either as a light machine gun or a medium machine gun. Deployed on a tripod and used for sustained-fire it is a medium machine gun; if deployed with a bipod with the operator in prone position and firing short bursts it is a light machine gun.

Light machine guns are also designed to be fired from the hip or on the move as a form of suppressive fire intended to pin down the enemy. Marching fire is a specific tactic that relies on this capability.

Lighter modern LMGs have enabled them to be issued down at the fireteam level, with two or three at the section/squad level.

Ammunition feed

Many light machine guns (such as the Bren gun or the M1918 Browning Automatic Rifle) were magazine-fed. Others, such as the MG 34, could be fed either from a belt or a magazine. Modern light machine guns are designed to fire more rounds of a smaller caliber and, as such, tend to be belt-fed from a detachable box magazine, some such as the FN Minimi will also accept rifle magazine feeding as an auxiliary measure when belted ammunition has been exhausted.

It is mainly used in wars or in areas which are situated with international borders....

Heckler & Koch MP5

                                             

     

The Heckler & Koch MP5 (from German: Maschinenpistole 5, "machine pistol model 5") is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants of the MP5,including a semi-automatic version.

The MP5 is one of the most widely used submachine guns in the world, having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations.

In the 1990s, Heckler & Koch developed the Heckler & Koch UMP, the MP5's successor; both are available as of 2013.

Features

The first MP5 models used a double-column straight box magazine, but since 1977, slightly curved, steel magazines are used with a 15-round capacity (weighing 0.12 kg) or a 30-round capacity

The adjustable iron sights (closed type) consist of a rotating rear diopter drum and a front post installed in a hooded ring. The rear sight is adjustable for both windage and elevation with the use of a special tool, being adjusted at the factory for firing at 25m with standard 124 grains FMJ 9x19mm NATO ammunition; the drum provides four different apertures of varying width used to adjust the light entrance in the diopter system, according to the user's eye relief and tactical situation, and not for firing at 25, 50, 75 and 100m as some people wrongly imagine.

The MP5 has a hammer firing mechanism. The trigger group is housed inside an interchangeable polymer trigger module (with an integrated pistol grip) and equipped with a three-position fire mode selector that serves as the manual safety toggle. The “S” or Sicher position in white denotes weapon safe, “E” or Einzelfeuer in red represents single fire, and “F” or Feuerstoß (also marked in red) designates continuous fire. The SEF symbols appear on both sides of the plastic trigger group. The selector lever is actuated with the thumb of the shooting hand and is located only on the left side of the original SEF trigger group or on both sides of the ambidextrous trigger groups. The safety/selector is rotated into the various firing settings or safety position by depressing the tail end of the lever. Tactile clicks (stops) are present at each position to provide a positive stop and prevent inadvertent rotation. The "safe" setting disables the trigger by blocking the hammer release with a solid section of the safety axle located inside the trigger housing.

The non-reciprocating cocking handle is located above the handguard and protrudes from the cocking handle tube at approximately a 45° angle. This rigid control is attached to a tubular piece within the cocking lever housing called the cocking lever support, which in turn, makes contact with the forward extension of the bolt group. It is not however connected to the bolt carrier and therefore cannot be used as a forward assist to fully seat the bolt group. The cocking handle is held in a forward position by a spring detent located in the front end of the cocking lever support which engages in the cocking lever housing. The lever is locked back by pulling it fully to the rear and rotating it slightly clockwise where it can be hooked into an indent in the cocking lever tube.

This pistol is also used by the jawans of BSF (Border Security force ). It is also used by the police of many countries 

Glock

The Glock pistol, sometimes referred to by the manufacturer as Glock "Safe Action" Pistol, is a series of polymer-framed, short recoil operated, locked breech semi-automatic pistols designed and produced by Glock Ges.m.b.H., located in Deutsch-Wagram, Austria.

Despite initial resistance from the market to accept a "plastic gun" due to durability and reliability concerns, and fears that the pistol would be "invisible" to metal detectors in airports, Glock pistols have become the company's most profitable line of products, commanding 65% of the market share of handguns for United States law enforcement agencies as well as supplying numerous national armed forces and security agencies worldwide. Glocks are also popular weapons amongst civilians for home/self defense and concealed/open carry.

The company's founder, engineer Gaston Glock, had no experience with firearm design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock did, however, have extensive experience in advanced synthetic polymers, knowledge of which was instrumental in the company's design of the first commercially successful line of pistols with a polymer frame. Glock introduced ferritic nitrocarburizing into the firearms industry as an anti-corrosion surface treatment for metal gun parts.

                                                         

Glock became aware of the Austrian Army's planned procurement and in 1982 assembled a team of Europe's leading handgun experts from military, police and civilian sport shooting circles to define the most desirable characteristics in a combat pistol.[10] Within three months, Glock developed a working prototype that combined proven mechanisms and traits from previous pistol designs. The new weapon made extensive use of synthetic materials and modern manufacturing technologies in its design, making it a very cost-effective candidate. Several samples of the 9×19mm Glock 17 (so named because it was the 17th set of technical drawings of the company) were submitted for assessment trials in early 1982, and after passing all of the exhaustive endurance and abuse tests, Glock emerged as the winner with the Model 17.

The handgun was adopted into service with the Austrian military and police forces in 1982 as the P80 (Pistole 80), with an initial order for 25,000 guns. The Glock 17 outperformed 8 different pistols from five other established manufacturers (Heckler & Koch of Germany offered their P7M8, P7M13 and P9S, SIG Sauer of Germany bid with their P220 and P226 models, Beretta of Italy submitted their model 92SB-F, FN Herstal proposed an updated variant of the Browning Hi-Power and the home-grown Steyr entered the competition with the GB).

The results of the Austrian trials sparked a wave of interest in Western Europe and overseas, particularly in the United States, where a similar effort to select a service-wide replacement for the M1911 had been ongoing since the late 1970s (known as the Joint Service Small Arms Program). In late 1983, the United States Department of Defense inquired about the Glock pistol and received four samples of the Glock 17 for unofficial evaluation. Glock was then invited to participate in the XM9 Personal Defense Pistol Trials, but declined because the DOD specifications would require extensive retooling of production equipment and providing 35 test samples in an unrealistic time frame.

Shortly thereafter, the Glock 17 was accepted into service with the Norwegian, and Swedish Armed Forces, surpassing all prior NATO durability standards. As a result, the Glock 17 became a standard NATO-classified sidearm and was granted a NATO Stock Number

By 1992, some 350,000 pistols had been sold in more than 45 countries, including 250,000 in the United States alone. IT is also used by COBRA (commando battalion for resolute action) commandoes . It is very accurate.
