Firearms

A **Firearm** is a type of weapon from which projectiles are discharged by the ignition of an explosive propellant. It is also known as **Gun** (more referred as **Firearm**) is a device or ranged weapon designed to propel a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons), or gas (e.g. light-gas gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Tasers, spearguns and harpoon guns). A large-caliber gun is also called a *cannon*.

In many cases, Firearms were widely used by both Law Enforcement, Militaries and Civilians for protection and self-defense against any attackers, in this case, it is a weapon designed to kill whether it's in a close-range or in long range.

In GATE crossover series (Thus the JTF fought Here and Thus the Alliance liberates), majority of all military personnel uses Firearms for protection against enemy forces like the Saderans and the Fire Nation. They carry a different variety of weapons depending on their task and provide cover-fire for the Squad.

## Description

A firearm is a barreled ranged weapon that inflicts damage on targets by launching one or more projectiles driven by rapidly expanding high-pressure gas produced by exothermic combustion (deflagration) of a chemical propellant, historically black powder, now smokeless powder.

In the military, firearms are categorized into *heavy* and *light* weapons regarding their portability by infantry. Light firearms are those that can be readily carried by individual foot soldier, though they might still require more than one individual (crew-served) to achieve optimal operational capacity. Heavy firearms are those that are too large and heavy to be transported on foot, or too unstable against recoil, and thus require the support of a weapons platform (e.g. a fixed mount, wheeled carriage, vehicle, aircraft or water vessel) to be tactically mobile or useful.

The subset of light firearms that only use kinetic projectiles and are compact enough to be operated to full capacity by a single infantryman (individual-served) are also referred to as **small arms**. Such firearms include handguns such as pistols, revolvers, and derringers; and long guns such as rifles (and their subtypes), shotguns, submachine guns, and machine guns.

Within military usage, the term "**gun**" refers only to artillery that fires projectiles at high velocity, such as tank guns, or naval guns (naval guns are never referred to as cannons). A gunner is a member of the team charged with the task of operating and firing a gun. Thus, by military terms, mortars and all hand-held firearms (rifles ) are excluded from this definition.

The word "**gun**" is also applied to some more or less vaguely gun-like tools, such as staple guns and glue guns.

The etomology of the word "**gun**" is found in Middle English as "*gonne*", and seems to come from the Germanic woman's name Gunhild or Gundhild meaning "*war sword*". This Germanic name also applied to an early cannon.

## Types of Firearms

There are many variety of Fire Arms that can be choose from, depending on what types.

**Pistol**
A pistol is a type of handgun. The word "pistol" first appeared in English c. 1570, when early handguns were produced in Europe, and is derived from the Middle French pistolet (c. 1550), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled).

**Shotgun**
A shotgun (also known as a scattergun, peppergun, or historically as a fowling piece) is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which usually discharges numerous small pellet-like spherical sub-projectiles called shot, or sometimes a single solid projectile called a slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available.

**Rifle**
A rifle is a long-barreled firearm designed for accurate shooting and higher stopping power, with a barrel that has a helical pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports and crime.

Types of Rifles:

* Assault Rifles
* Battle Rifles
* Sniper Rifles
* Marksman Rifles
* Semi-automatic Rifles
* Bolt-Action Rifles

**Machine Gun**
A machine gun is a fully automatic, rifled auto-loading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower and are not considered true machine guns. Submachine guns fire handgun cartridges rather than rifle cartridges, therefore they are not considered machine guns, while automatic firearms of 20 mm (0.79 in) caliber or more are classified as autocannons rather than machine guns.

**Submachine Gun**
A Submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix "sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.

The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of SMGs were made for use by regular troops, clandestine commandos, and partisans alike. New submachine gun designs appeared frequently during the Cold War. Submachine gun usage in frontline combat decreased into the 1980s and 1990s, and in the 21st century, submachine guns have largely been replaced by assault rifles, which have a longer effective range, have better stopping power, and can penetrate the helmets and body armor used by modern infantry. However, they are still used by special forces and police tactical units for close-quarters combat because they are "a pistol-caliber weapon that's easy to control, and less likely to overpenetrate the target".

## Depiction in the Crossover series

Firearms were used by the militaries of Japan, United States, Britain and France during the events of **GATE: Thus the JTF Fought Here!**, it is shown that the Japanese and Americans, followed by the British and the French coalition troops on their campaign against the Saderan Empire during the Saderan-Japanese War of 2015, the Japanese forces of the JGSDF prefer the use of their old firearms (with the exception of their Special Forces), while the Americans, British and French troops uses both new and modern Firearms against the primitive soldiers of the Saderan Army and their Allied Kingdoms until the end of the War in 2016. In the latter, the forces of Princess Pina Co Lada allowed the limited use of Firearms on her new Army to defend themselves with the help from the Americans and Italians for providing their new weapons for the new Saderan Army.

However in the year 2017 at the events of **GATE: Thus the Alliance liberates the Avatar World**, the Japanese was allowed to use their modern Firearms like the Howa Type 89 against the Fire Nation invaders at the late Hundred Year War when the IFN attacked Umeda, followed by the Australians, Singaporeans, Filipinos, Taiwanese and Israelis who use their preferred firearms on their own Arsenal, meanwhile the Fire Nation developed their own Firearms based on Naval officer Zhao from the documents he found along with the ancient scrolls about the Spirits, in the latter with the stolen weapons from the fallen SAT Operators during the Battle of Umeda. On earthrealm however, many resistance were killed during the first invasion of the Fire Nation, when the Fire Nation introduced their first weapon based on Rifled Muskets and Repeating Rifles that killed hundreds of Resistance fighters, leaving Aang and his allies to be demoralized and defeated as the Fire Nation proved their new weapons for their non-bending soldiers proved to be powerful enough to take-down both Benders and non-Benders, though it was not considered superior to the modern Firearms used by the JTF Coalition Forces as they arrived on Earthrealm.
